maven 打包可执行jar的方法

在这以前，我本身找了点maven的东西添加进来

Maven内置变量说明：
	${basedir} 项目根目录
	${project.build.directory} 构建目录，缺省为target
	${project.build.outputDirectory} 构建过程输出目录，缺省为target/classes
	${project.build.finalName} 产出物名称，缺省为${project.artifactId}-${project.version}
	${project.packaging} 打包类型，缺省为jar
	${project.xxx} 当前pom文件的任意节点的内容

方式1

修改pom.xml增长以下内容

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-jar-plugin</artifactId>
	<version>2.4</version>
	<configuration>
		<archive>
			<manifest>
				<addClasspath>true</addClasspath>
				<classpathPrefix>lib/</classpathPrefix>
				<mainClass>com.sysware.HelloWorld</mainClass>
			</manifest>
		</archive>
	</configuration>
</plugin>

运行mvn clean package便可

批注：

通过我本人自测以后发现，这种方式虽然能够打包，可是不会将依赖包也添加进去。因此我认为这种方式的打包适合写一个工具，而后打成JAR包，导入其余工程使用，若是是一个单独运行的JAR包，则不适用。

方式2

在pom.xml增长以下内容

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-assembly-plugin</artifactId>
	<version>2.3</version>
	<configuration>
		<appendAssemblyId>false</appendAssemblyId>
		<descriptorRefs>
			<descriptorRef>jar-with-dependencies</descriptorRef>
		</descriptorRefs>
		<archive>
			<manifest>
				<mainClass>com.juvenxu.mvnbook.helloworld.HelloWorld</mainClass>
			</manifest>
		</archive>
	</configuration>
	<executions>
		<execution>
			<id>make-assembly</id>
			<phase>package</phase>
			<goals>
				<goal>assembly</goal>
			</goals>
		</execution>
	</executions>
</plugin>

运行mvn assembly:assembly （ 我本身使用mvn clean package也是能够的）

批注：

这个方式和方式1不一样，这种打包方式，将项目及所依赖的全部jar包打包成一个jar，让打出来的JAR包成为一个可独立运行的JAR包

方式3

批注：

    我本身在博主的基础上，添加了一些配置和注释

    方式3和方式4都是比较复杂的打包方式，可是能够本身定义细节，好比须要哪些文件被打包，哪些文件不打包进去，哪些文件放到哪里等等。
