Maven 2 生成期间未启动exec maven插件目标

你好

在maven构建过程中，我尝试运行一个main方法。因此，我在pom.xml中添加了execmaven插件和以下代码片段

<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>

我还尝试创建一个空的新项目来测试pom中的其他依赖是否会导致问题，但没有成功。在~/.m2文件夹中的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任何其他内容

它只是不能启动它。当我删除org.codehouse下repo中的所有工件时，它没有下载execmaven插件。只有在我执行命令行调用时

有什么提示吗？提前谢谢

编辑：我忘了提到我使用过“mvn清洁安装”。所以它应该已经过了编译阶段

编辑：

到目前为止，我还不能解决这个问题。谢谢你迄今为止的回答！我会再次尝试提供所有信息，希望你们中的一个，找到可疑的部分。我再也不知道了。。。。 我所做的：

• 删除我的maven代理中的文件夹org/codehouse/mojo。仅在加载依赖项时显示
• 显示一些java和maven版本信息
• 使用：mvn-clean install构建项目（应该通过测试阶段来执行我的主方法）
• 执行main方法显示，execmaven插件仅在之后加载并工作

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插件，该插件应该执行main方法。我说得对吗

现在再次修改pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

和JUnit测试类：

package at.test;
import org.junit.Test;
import at.test.ExecTest;

public class ExecTestTest {

  @Test
    public void testTestTest() {
      System.err.println("JUnit Test call:");
      ExecTest.main(null);
      System.err.println("end of junit test.");
    }
}

---

编译阶段可能不合适，您尝试过吗

 <phase>test</phase>

测试

如果将其设置为phase compile，则必须告诉maven在运行时需要运行compile。使用maven命令无法通过任何阶段。您应该拥有

mvncileexec:java…

或更高版本（测试、安装…）

这是我对exec maven插件（使用mvn clean软件包）的用法：

org.codehaus.mojo
execmaven插件
1.2
测试
JAVA
com.xxx.LanguageGenerator
${project.build.outputDirectory}/build/PMLanguage.xls
PM${project.version}
${project.build.outputDirectory}/com/laco/projectmaster/props/resources
在maven构建期间创建（POM版本：
${project.version}）

我终于找到了问题所在。这是一个相当愚蠢的错误：

在pom.xml中，我在

节点周围使用了

Maven没有抱怨，但忽略了所有插件配置。 也许有人可以利用这些信息

谢谢你的帮助

@user375251正在运行什么命令

mvn clean test

，

mvn clean install

？另外，由于要将exec java目标绑定到编译阶段，因此不需要将exec:java-Dexec.mainClass=“at.xyz.dls.util.JasperReportCompiler”添加到maven命令中；简单的mvn编译应该可以做到这一点。我使用它的方式完全相同，但我使用的插件版本1.2。谢谢！我也有这个问题。
