使用maven-ant-plugin将条目添加到maven-jar-plugin内的清单文件中

Question

我正在使用maven-ant-plugin设置一个属性，我希望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呢？

更新:这是我的pom文件。我希望在maven-jar-plugin中将包含自定义类路径的属性"abc“的值添加到清单文件中。

如果您想要添加类路径，可以使用以下配置：

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