使用 maven-ant-plugin 向 maven-jar-plugin 内的清单文件添加一个条目

Question

我正在使用 maven-ant-plugin 设置一个属性，并且我希望将 maven-jar-plugin 中的该属性作为自定义条目放置在 jar 的清单文件中。 我怎样才能做到这一点？

更新：这是我的 pom 文件。我想要属性“abc”的值，它包含要添加到清单文件中的自定义类路径，在 maven-jar-plugin 中。

如果你想添加类路径，有一个配置可以这样做：

 <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    ...
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
        </manifest>
      </archive>
    </configuration>
    ...
