maven antrun插件中的父属性

我不知道 确切地 为什么 ${project.parent.basedir} http://jira.codehaus.org/browse/MNG-3597 ).

下面是一个使用gmaven的可怕解决方案:

<plugin>
  <groupId>org.codehaus.gmaven</groupId>
  <artifactId>gmaven-plugin</artifactId>
  <version>1.3</version>
  <executions>
    <execution>
      <id>set-custom-property</id>
      <phase>validate</phase>
      <goals>
        <goal>execute</goal>
      </goals>
      <configuration>
        <source>
          project.properties.setProperty('main.basedir', project.parent.basedir.toString())
        </source>
      </configuration>
    </execution>
  </executions>
</plugin>
<plugin>
  <artifactId>maven-antrun-plugin</artifactId>
  <version>1.6</version>
  <executions>
    <execution>
      <id>render-parameter-sql</id>
      <phase>validate</phase>
      <goals>
        <goal>run</goal>
      </goals>
      <configuration>
        <target>
          <echo>project.artifactId        : ${project.artifactId}</echo>
          <echo>project.parent.basedir    : ${project.parent.basedir}</echo>
          <echo>main.basedir              : ${main.basedir}</echo>
          <echo>project.basedir           : ${project.basedir}</echo>
          <echo>project.build.directory   : ${project.build.directory}</echo>
        </target>
      </configuration>
    </execution>
  </executions>
</plugin>

$ mvn validate

但我得说你想做什么( )是一个 坏习惯 ,模块应该是自包含的,而不是紧密耦合的。
