Eclipse下.project和.classpath做用

  1. classpath做用java

    定义项目的结构,如src、output、con、lib等。 eclipse

    源文件的具体位置(kind="src")maven

    运行的系统环境(kind="con")ui

    工程的library的具体位置信息(kind="lib")spa

    在每一个lib的xml子节点中,有关于它的其它配置信息(例如我配置的那个"javadoc_location")插件

    项目的输出目录(kind="output")debug

    样本:xml

    <?xml version="1.0" encoding="UTF-8"?>
    <classpath>
     <classpathentry kind="src" output="target/classes" path="src/main/java">
      <attributes>
       <attribute name="optional" value="true"/>
       <attribute name="maven.pomderived" value="true"/>
      </attributes>
     </classpathentry>
     <classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources">
      <attributes>
       <attribute name="maven.pomderived" value="true"/>
      </attributes>
     </classpathentry>
     <classpathentry kind="src" output="target/test-classes" path="src/test/java">
      <attributes>
       <attribute name="optional" value="true"/>
       <attribute name="maven.pomderived" value="true"/>
      </attributes>
     </classpathentry>
     <classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources">
      <attributes>
       <attribute name="maven.pomderived" value="true"/>
      </attributes>
     </classpathentry>
     <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6">
      <attributes>
       <attribute name="maven.pomderived" value="true"/>
      </attributes>
     </classpathentry>
     <classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
      <attributes>
       <attribute name="maven.pomderived" value="true"/>
      </attributes>
     </classpathentry>
     <classpathentry kind="output" path="target/classes"/>
    </classpath>
     ip

  2. .project做开发

    工程名<name></name>

    工程注释描述<comment></comment>

    运行时须要的额外Eclipse插件<natures></natures>,及其具体加载方式信息<buildSpec></buildSpec>

    若是你在开发过程当中向工程里面加入了不少额外的插件,则必然会致使你的Eclipse启动速度变慢。在这种状况下,你能够到这个文件里面去掉一些插件,不过这样一来你在开启那些关联文件的时候会加载那些插件

         样本:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
 <name>log4j-jmx-gui</name>
 <comment></comment>
 <projects>
 </projects>
 <buildSpec>

<buildCommand>
   <name>org.eclipse.jdt.core.javabuilder</name>
   <arguments>
   </arguments>
  </buildCommand>

  <buildCommand>   <name>org.eclipse.m2e.core.maven2Builder</name>   <arguments>   </arguments>  </buildCommand> </buildSpec> <natures>  <nature>org.eclipse.m2e.core.maven2Nature</nature>  <nature>org.eclipse.jdt.core.javanature</nature> </natures></projectDescription>
