4.2 变量

1) 问：怎样使用变量替换？项目中的某个配置文件比方jdbc.properties使用了一些pom中的变量，怎样在公布中使用包括真实内容的终于结果文件？

答：使用资源过滤功能，比方：css

< project >
    ... 
     < properties >
         < jdbc.driverClassName >com.mysql.jdbc.Driver </ jdbc.driverClassName >
         < jdbc.url >jdbc:mysql://localhost:3306/development_db </ jdbc.url >
         < jdbc.username >dev_user </ jdbc.username >
         < jdbc.password >s3cr3tw0rd </ jdbc.password >
     </ properties >
    ... 
     < build >
         < resources >
             < resource >
                 < directory >src/main/resources </ directory >
                 < filtering >true </ filtering >
             </ resource >
         </ resources >
     </ build >
    ... 
     < profiles >
         < profile >
             < id >production </ id >
             < properties >
                 < jdbc.driverClassName >oracle.jdbc.driver.OracleDriver </ jdbc.driverClassName >
                 < jdbc.url >jdbc:oracle:thin:@proddb01:1521:PROD </ jdbc.url >
                 < jdbc.username >prod_user </ jdbc.username >
                 < jdbc.password >s00p3rs3cr3t </ jdbc.password >
             </ properties >
         </ profile >
     </ profiles >
</ project >

2) 问： maven-svn-revision-number-plugin 插件说明

答： maven-svn-revision-number-plugin 可以从 SVN 中获取版本，并将其变成环境变量，交由其它插件或者profile使用，具体帮助在这里 。通常和resource的filter机制同一时候使用html

< plugins >
     < plugin >
         < groupId >com.google.code.maven-svn-revision-number-plugin </ groupId >
         < artifactId >maven-svn-revision-number-plugin </ artifactId >
         < version >1.3 </ version >
         < executions >
             < execution >
                 < goals >
                     < goal >revision </ goal >
                 </ goals >
             </ execution >
         </ executions >
         < configuration >
             < entries >
                 < entry >
                     < prefix >prefix </ prefix >
                 </ entry >
             </ entries >
         </ configuration >
     </ plugin >
</ plugins >

这段代码负责把resource文件里的内容替换成适当内容java

repository = ${prefix.repository}
path = ${prefix.path}
revision = ${prefix.revision}
mixedRevisions = ${prefix.mixedRevisions}
committedRevision = ${prefix.committedRevision}
status = ${prefix.status}
specialStatus = ${prefix.specialStatus}

3）个人程序有些单元測试有错误。怎样忽略測试步骤？

有好几种方法都可以实现跳过单元測试步骤。一种是给mvn添加命令行參数 -Dmaven.test.skip=true 或者 -DskipTests=true 。第二种是给surefire插件添加參数。例如如下：mysql

<span class="kwrd"><</span><span class="html">project</span><span class="kwrd">></span>
  [...]
  <span class="kwrd"><</span><span class="html">build</span><span class="kwrd">></span>
    <span class="kwrd"><</span><span class="html">plugins</span><span class="kwrd">></span>
      <span class="kwrd"><</span><span class="html">plugin</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">groupId</span><span class="kwrd">></span>org.apache.maven.plugins<span class="kwrd"></</span><span class="html">groupId</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">artifactId</span><span class="kwrd">></span>maven-surefire-plugin<span class="kwrd"></</span><span class="html">artifactId</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">version</span><span class="kwrd">></span>2.8<span class="kwrd"></</span><span class="html">version</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">configuration</span><span class="kwrd">></span>
          <span class="kwrd"><</span><span class="html">skipTests</span><span class="kwrd">></span>true<span class="kwrd"></</span><span class="html">skipTests</span><span class="kwrd">></span>
        <span class="kwrd"></</span><span class="html">configuration</span><span class="kwrd">></span>
      <span class="kwrd"></</span><span class="html">plugin</span><span class="kwrd">></span>
    <span class="kwrd"></</span><span class="html">plugins</span><span class="kwrd">></span>
  <span class="kwrd"></</span><span class="html">build</span><span class="kwrd">></span>
  [...]
<span class="kwrd"></</span><span class="html">project</span><span class="kwrd">></span>
4) 假设仅仅想执行单个測试用例，是否能实现？

可以，执行时候添加命令行參数 -Dtest=MyTest 就能够，当中MyTest是所需要执行的单元測试用例名称，但是不需要包括package部分。c++

4.3 编译

1) 问：怎样给插件指派參数？比方我要设置一些编译參数

答：下面内容设定编译器编译java1.5的代码sql

< project >
    ... 
     < build >
        ... 
         < plugins >
             < plugin >
                 < artifactId >maven-compiler-plugin </ artifactId >
                 < configuration >
                     < source >1.5 </ source >
                     < target >1.5 </ target >
                 </ configuration >
             </ plugin >
         </ plugins >
        ... 
     </ build >
    ... 
</ project >

要设置其它插件的參数也可以，请參考相应插件的帮助信息
2) 问：个人文件夹是非标准的文件夹结构。怎样设置让maven支持？

答：指定source文件夹和test-source文件夹就能够。apache

< build >
     < directory >target </ directory >
     < sourceDirectory >src </ sourceDirectory >
     < scriptSourceDirectory >js/scripts </ scriptSourceDirectory >
     < testSourceDirectory >test </ testSourceDirectory >
     < outputDirectory >bin </ outputDirectory >
     < testOutputDirectory >bin </ testOutputDirectory >
</ build >

这个样例把源码设置成了src文件夹，測试代码在test文件夹，因此输出到bin文件夹。

这里要注意，directory假设也设置成bin文件夹的话，maven打包的时候会引发死循环，因为directory是所有工做存放的地方。默认包括outputDirectory定义的文件夹在内。oracle

3) 我源码是UTF8格式的，我怎样在maven中指定？

设置一个变量就能够eclipse

< project >
    ... 
     < properties >
         < project.build.sourceEncoding >UTF-8 </ project.build.sourceEncoding >
     </ properties >
    ... 
</ project >
{color:blue}以上是官方给出的解决方式。但是通过尝试这样仅仅能影响到resource处理时候的编码{color}，真正实用的是例如如下配置： 
{code:xml}
<build>
  ...
    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <encoding>UTF-8</encoding>
      </configuration>
    </plugin>
  ...
</build>
{code}
. 问：个人项目除了main/java文件夹以外。还加了其它的c++文件夹，想要一并编译，怎样作？
答：使用native插件，详细配置方法參考[http://mojo.codehaus.org/maven-native/native-maven-plugin/] 
{code:xml}
<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>native-maven-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
</plugin>    
{code}
. 问：我想要把project的所有依赖的jar都一块儿打包，怎么办？
答：首先改动maven的配置文件，给maven-assembly-plugin添加一个jar-with-dependencies的描写叙述。

{code:xml}
<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>
{code}
而后使用命令打包就能够： 
mvn assembly:assembly
. 问：我想把main/scripts中的内容一块儿打包公布，怎样作？
答：在pom中配置额外的资源文件夹。假设需要的话。还可以指定资源文件夹的输出位置 
{code:xml}
<build>
  ...
  <resources>
    <resource>
      <filtering>true</filtering>
      <directory>src/main/command</directory>
      <includes>
        <include>run.bat</include>
        <include>run.sh</include>
      </includes>
      <targetPath>/abc</targetPath>
    </resource>
    <resource>
      <directory>src/main/scripts</directory>
    </resource>
  </resources>
  ...
</build>
{code}
. 问：我有多个源码文件夹，但是maven仅仅支持一个main src和一个test src，怎么办？
答：使用另一个插件，并仿照例如如下配置pom 
{code:xml}
<plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>build-helper-maven-plugin</artifactId>
        <version>1.1</version>
        <executions>
          <execution>
            <id>add-source</id>
            <phase>generate-sources</phase>
            <goals>
              <goal>add-source</goal>
            </goals>
            <configuration>
              <sources>
                <source>src/config/java</source>
                <source>src/main/java</source>
                <source>src/member/java</source>
              </sources>
            </configuration>
          </execution>
        </executions>
      </plugin>
{code}
. 问：个人源码文件夹中有一部分文件我不想让maven编译，怎么作？
答：使用一个maven插件，而后使用includes和excludes。

同理。也可以处理资源的过滤。ssh

{code:xml}
<build>
  <sourceDirectory>http://www.cnblogs.com/src/java</sourceDirectory>
  <plugins>
    <plugin>
      <groupId>com.sun.enterprise</groupId>
      <artifactId>hk2-maven-plugin</artifactId>
      <configuration>
        <includes>
          <include>com/sun/logging/LogDomains.*</include>
          <include>com/sun/enterprise/util/OS.java</include>
          <include>com/sun/enterprise/util/io/FileUtils.java</include>
          <include>com/sun/enterprise/util/zip/**</include>
          <include>com/sun/enterprise/util/i18n/**</include>
          <include>com/sun/enterprise/deployment/backend/IASDeploymentException.java</include>
        </includes>
        <excludes>
          <exclude>com/sun/enterprise/config/ConfigBeansFactory.java</exclude>
          <exclude>com/sun/enterprise/config/clientbeans/**</exclude>
        </excludes>
      </configuration>
    </plugin>
  </plugins>
  <resources>
    <resource>
      <directory>http://www.cnblogs.com/src/java</directory>
      <includes>
        <include>**/*.properties</include>
      </includes>
    </resource>
  </resources>
</build>
{code}
. 问：个人项目是一个纯的html组成的项目，没有不论什么的java代码，怎么跳过编译过程？
答：配置例如如下 
{code:xml}
<build>
  <sourceDirectory>src/java</sourceDirectory>
  <plugins>
    <plugin>
    <groupId>com.sun.enterprise</groupId>
    <artifactId>hk2-maven-plugin</artifactId>
    </plugin>
  </plugins>
</build>
{code}
. 问：个人project里用hibernate，想在编译时候本身主动生成ddl，怎样作？
答：加入插件 
hibernate3-maven-plugin
。依照例如如下配置： 
{code:xml}
        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>hibernate3-maven-plugin</artifactId>
          <version>2.1</version>
          <configuration>
            <components>
              <component>
                <name>hbm2ddl</name>
                <implementation>annotationconfiguration</implementation>
              </component>
            </components>
          </configuration>
          <dependencies>
            <dependency>
              <groupId>hsqldb</groupId>
              <artifactId>hsqldb</artifactId>
              <version>${hsqldb.version}</version>
            </dependency>
          </dependencies>
        </plugin>
{code}
. 问：我能用maven支持eclipse RCP项目吗？

答：固然可以，你可以使用插件 Tycho，具体内容可以參考这里[http://mattiasholmqvist.se/2010/02/building-with-tycho-part-1-osgi-bundles/].

 <plugin>
  <groupid>org.sonatype.tycho</groupid>
  <artifactid>target-platform-configuration</artifactid>
  <version>0.7.0</version>
  <configuration>
    <resolver>p2</resolver>
  </configuration>
</plugin>
另外。老牌的pde-maven-plugin就不要用了，已经好几年没见更新了。

4.4 ant互动

1) 怎样在maven编译时候执行ant脚本？

使用专门的antrun插件，并且在target标签内部增长ant的代码

      <span class="kwrd"><</span><span class="html">plugin</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">artifactId</span><span class="kwrd">></span>maven-antrun-plugin<span class="kwrd"></</span><span class="html">artifactId</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">version</span><span class="kwrd">></span>1.6<span class="kwrd"></</span><span class="html">version</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">executions</span><span class="kwrd">></span>
          <span class="kwrd"><</span><span class="html">execution</span><span class="kwrd">></span>
            <span class="kwrd"><</span><span class="html">phase</span><span class="kwrd">></span> <span class="rem"><!-- 生命周期阶段 --></span> <span class="kwrd"></</span><span class="html">phase</span><span class="kwrd">></span>
            <span class="kwrd"><</span><span class="html">configuration</span><span class="kwrd">></span>
              <span class="kwrd"><</span><span class="html">target</span><span class="kwrd">></span>
                <span class="rem"><!-- 增长target内部的代码 --></span>
              <span class="kwrd"></</span><span class="html">target</span><span class="kwrd">></span>
            <span class="kwrd"></</span><span class="html">configuration</span><span class="kwrd">></span>
            <span class="kwrd"><</span><span class="html">goals</span><span class="kwrd">></span>
              <span class="kwrd"><</span><span class="html">goal</span><span class="kwrd">></span>run<span class="kwrd"></</span><span class="html">goal</span><span class="kwrd">></span>
            <span class="kwrd"></</span><span class="html">goals</span><span class="kwrd">></span>
          <span class="kwrd"></</span><span class="html">execution</span><span class="kwrd">></span>
        <span class="kwrd"></</span><span class="html">executions</span><span class="kwrd">></span>
      <span class="kwrd"></</span><span class="html">plugin</span><span class="kwrd">></span>

2）怎样在ant脚本中引用maven的classpath？

maven给每一个依赖都生成了一个属性，格式为"groupId:artifactId[:classifier]:type"，比方，假设一下样例就显示依赖的org.apache.common-util的jar文件路径

<span class="kwrd"><</span><span class="html">echo</span> <span class="attr">message</span><span class="kwrd">="Dependency JAR Path: ${org.apache:common-util:jar}"</span><span class="kwrd">/></span>

另外，maven还提早定义了四个classpath的引用。他们是

  • maven.compile.classpath
  • maven.runtime.classpath
  • maven.test.classpath
  • maven.plugin.classpath

3）怎样使用antrun插件执行外部的build文件？

很是easy，直接在antrun里边使用ant指令就能够。例如如下：

<span class="kwrd"><</span><span class="html">plugin</span><span class="kwrd">></span>
    <span class="kwrd"><</span><span class="html">groupId</span><span class="kwrd">></span>org.apache.maven.plugins<span class="kwrd"></</span><span class="html">groupId</span><span class="kwrd">></span>
    <span class="kwrd"><</span><span class="html">artifactId</span><span class="kwrd">></span>maven-antrun-plugin<span class="kwrd"></</span><span class="html">artifactId</span><span class="kwrd">></span>
    <span class="kwrd"><</span><span class="html">version</span><span class="kwrd">></span>1.6<span class="kwrd"></</span><span class="html">version</span><span class="kwrd">></span>
    <span class="kwrd"><</span><span class="html">executions</span><span class="kwrd">></span>
        <span class="kwrd"><</span><span class="html">execution</span><span class="kwrd">></span>
            <span class="kwrd"><</span><span class="html">id</span><span class="kwrd">></span>compile<span class="kwrd"></</span><span class="html">id</span><span class="kwrd">></span>
            <span class="kwrd"><</span><span class="html">phase</span><span class="kwrd">></span>compile<span class="kwrd"></</span><span class="html">phase</span><span class="kwrd">></span>
            <span class="kwrd"><</span><span class="html">configuration</span><span class="kwrd">></span>
                <span class="kwrd"><</span><span class="html">target</span><span class="kwrd">></span>
                    <span class="rem"><!-- 同一时候传递内置的classpath给外部ant文件 --></span>
                    <span class="kwrd"><</span><span class="html">property</span> <span class="attr">name</span><span class="kwrd">="compile_classpath"</span> <span class="attr">refid</span><span class="kwrd">="maven.compile.classpath"</span><span class="kwrd">/></span>
                    <span class="kwrd"><</span><span class="html">property</span> <span class="attr">name</span><span class="kwrd">="runtime_classpath"</span> <span class="attr">refid</span><span class="kwrd">="maven.runtime.classpath"</span><span class="kwrd">/></span>
                    <span class="kwrd"><</span><span class="html">property</span> <span class="attr">name</span><span class="kwrd">="test_classpath"</span> <span class="attr">refid</span><span class="kwrd">="maven.test.classpath"</span><span class="kwrd">/></span>
                    <span class="kwrd"><</span><span class="html">property</span> <span class="attr">name</span><span class="kwrd">="plugin_classpath"</span> <span class="attr">refid</span><span class="kwrd">="maven.plugin.classpath"</span><span class="kwrd">/></span>
    
                    <span class="kwrd"><</span><span class="html">ant</span> <span class="attr">antfile</span><span class="kwrd">="${basedir}/build.xml"</span><span class="kwrd">></span>
                        <span class="kwrd"><</span><span class="html">target</span> <span class="attr">name</span><span class="kwrd">="test"</span><span class="kwrd">/></span>
                    <span class="kwrd"></</span><span class="html">ant</span><span class="kwrd">></span>
                <span class="kwrd"></</span><span class="html">target</span><span class="kwrd">></span>
            <span class="kwrd"></</span><span class="html">configuration</span><span class="kwrd">></span>

. 问：怎样在ant中使用maven的功能？
答：使用ant的[maven task|http://maven.apache.org/ant-tasks/index.html]。只是仅仅有ant 1.6以上和jdk 1.5环境才支持。

h4. 測试相关

. 问：怎样忽略某个阶段的结果？比方单元測试不必定要全正确
答：给插件添加testFailureIgnore參数。并设置为false。

假设要屏蔽该阶段，则用 

<skip>true</skip>
{code:xml}
<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <testFailureIgnore>true</testFailureIgnore>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>
{code}
. 问：我怎样在maven中增长PMD，CheckStyle，JDepend等检查功能？
答：增长PMD检查。下面代码假设在 
reporting
节点中增长则在 
mvn site
中运行。假设在 
build
节点中增长。则在build的时候本身主动执行检查。具体配置參考[pmd插件使用说明|http://maven.apache.org/plugins/maven-pmd-plugin/] 
{code:xml}
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-pmd-plugin</artifactId>
        <version>2.5</version>
      </plugin>
    </plugins>
{code}
增长 checkstyle 检查。具体配置參考[checkstyle插件使用说明|http://maven.apache.org/plugins/maven-checkstyle-plugin/]，相同注意放置在reporting和build节点中的差异（所有报表类插件都要相同注意）： 
{code:xml}
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-checkstyle-plugin</artifactId>
        <version>2.5</version>
      </plugin>
{code}
增长 simian 的支持。simian是一个支持代码类似度检查的工具，眼下有maven插件，也有checkstyle的插件。

它不只可以检查java，甚至可以支持文本文件的检查。

具体帮助信息參考[这里|http://www.redhillconsulting.com.au/products/simian/]。simian 的 maven插件在[这里|http://mojo.codehaus.org/simian-report-maven-plugin/introduction.html]
