exec-maven-plugin目标在构建期间未启动

你好,

我尝试在maven构建过程中运行main方法.因此,我将exec-maven-plugin和以下代码段添加到我的pom.xml中

<plugin>
     <!-- http://www.vineetmanohar.com/2009/11/3-ways-to-run-java-main-from-maven/ -->
     <groupId>org.codehaus.mojo</groupId>
     <artifactId>exec-maven-plugin</artifactId>
     <version>1.1.1</version>
     <executions>
      <execution>
       <id>compile-reports</id>
       <phase>compile</phase>
       <goals>
        <goal>java</goal>
       </goals>
       <configuration>
        <mainClass>at.xyz.dls.util.JasperReportCompiler</mainClass>
       </configuration>
      </execution>
     </executions>
    </plugin>

当我从命令行调用它时,主类存在并且也被执行:

mvn exec:java -Dexec.mainClass="at.xyz.dls.util.JasperReportCompiler"

我还尝试创建一个空的新项目进行测试,如果pom中的其他依赖性导致问题,但没有成功.在〜/ .m2文件夹的maven settings.xml中,只有镜像条目,但没有可能导致问题的配置文件或其他任何内容.

它只是没有启动它.当我在org.codehouse下删除我的repo中的所有工件时,它没有下载exec-maven-plugin.只有当我进行命令行调用时.

任何提示？提前致谢!

编辑:我忘了提到我用过"mvn clean install".所以它应该已经通过了编译阶段......

编辑:

到目前为止,我无法解决问题.到目前为止,感谢您的回答!我会再次尝试提供所有信息,希望你们其中一个人找到可疑的部分.我不知道了......

我做了什么:

删除我的maven代理中的文件夹org/codehouse/mojo.只是为了显示,加载依赖项时.
显示一些java和maven版本信息
用以下代码构建项目:mvn -clean install(应该通过测试阶段来执行我的main方法)
执行main方法显示,exec-maven-plugin只在之后加载并运行

据我所知,调用"mvn clean install"应该通过测试阶段(测试执行...),因此应该调用exec-maven-plugin,它应该执行main方法.我对吗？

最后我发现了问题.这是一个非常愚蠢的错误:

在pom.xml中我使用<pluginManagement>了<plugins>节点周围.

Maven没有抱怨,但忽略了所有插件配置.也许有人可以使用这些信息......

谢谢你的帮助!
