在Maven中，我如何生成一个包含我正在构建的工件的类路径文件？

我使用maven-dependency-plugin:build-classpath来构建类路径文件。为了支持遗留部署，除了通常的一组依赖JAR之外，我还需要这个文件包含我正在构建的工件。在Maven中，我如何生成一个包含我正在构建的工件的类路径文件？

当前classpath的文件：

dep1.jar:dep2.jar

类路径的文件我想：

project-I'm-building.jar:dep1.jar:dep2.jar

我使用maven-antrun-插件生成包含类路径的构件JAR文件考虑，然后使用build-classpath选项添加依赖关系JAR。这看起来虽然不起眼。有没有更好的办法？
