maven antrun 插件

Question

我的 pom 中有以下内容：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ant-plugin</artifactId>
    <version>2.3</version>
    <configuration>
       <target>
          <echo
            message="hello ant, from Maven!" />
          <echo>Maybe this will work?</echo>
       </target>
    </configuration>
</plugin>

然而，当我运行 'mvn antrun:run' 时，我得到这个：

[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'antrun'.
[INFO] ------------------------------------------------------------------------
[INFO] Building myProject
[INFO]    task-segment: [antrun:run]

为什么回声没有出现？

TIA

Answer 1

因为如果你想执行Ant，你应该使用 Maven AntRun Plugin任务，而不是 Maven Ant 插件（它用于生成从 POM 构建 Ant 1.6.2 或更高版本的文件）。修改您的插件配置如下：

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.5</version>
    <configuration>
      <target>
        <echo message="hello ant, from Maven!"/>
        <echo>Maybe this will work?</echo>
      </target>
    </configuration>
  </plugin>

调用 antrun:run 将起作用：

$ mvn antrun:run 
[INFO] Scanning for projects...
[INFO]

main:
     [echo] hello ant, from Maven!
     [echo] Maybe this will work?

确保 maven-antrun-plugin 使用足够新的版本。

我的项目中一个不相关的 BOM 将其锁定为 1.3，并且 被忽略。删除 BOM 并为 antrun 指定 1.7 后，回显起作用了。
