Question

我现在有一个使用外部依赖项的jar。我正在尝试创建一个包装内部所有外部依赖项的jar，并且只给我一个jar。我多次看到这个问题，但我仍然无法弄明白。我正在使用Ant，并复制了我在这里看到的一些例子。我正在使用zipgroupfileset来引用外部（现在是内部）jar。一旦我添加了zipgroupfileset，我就遇到了一个运行时错误，说我的Runner类无法找到。

Answer 1

简化事情：

创建单独的 sources jar 进行编译。然后，有一个没有源的单独的编译jar。
不包括第三方罐子。相反，请使用Ivy with Ant。 Ant将自动下载所需的jar。事实上，我看到只包含ivy.jar的来源，因此当你解开来源时会自动配置常春藤。您键入ant，所有内容都只是构建。

作为替代方案，您可以查看Maven，即现在打包的项目数量。实际上，如果您的jar是一个开源项目，您可以将其托管在OSS Maven存储库中。这样，甚至没有人需要手动下载你编译的jar。如果他们想要它，他们会配置他们的Maven项目为他们做。

Answer 2

我认为问题是你在jar任务中使用basedir =“bin”。然后你的zipgroupfileset的路径转换为bin / $ {external-lib-dir}

具有内部依赖性的Ant
