ANT 中有没有办法从 JAR 中提取一个类文件并将其放入另一个 JAR 中? [英] Is there a way in ANT to extract one class file from a JAR and put it in another JAR?

问题描述

我的 ANT 构建脚本使用名为 createEJBStubs 的 WebSphere 命令生成一个 JAR 文件，其中包含所有内容和一个新生成的类，即:com/myapp/services/_User_Service_Stub.class.

My ANT build script uses a WebSphere command called createEJBStubs that produces a JAR file with everything plus one new generated class, namely: com/myapp/services/_User_Service_Stub.class.

由于这个存根类仅用于在开发时运行 JUnit 测试，我希望它位于自己的 JAR 文件中.

Since this stub class is only used for running JUnit tests at dev time, I would like it to be in its own JAR file.

我如何告诉 ANT 复制 AAA.JAR 中匹配的所有内容，例如 _*Stub.class 并仅将这些文件复制到 BBB 中.JAR(也保持相同的目录/包结构)?

How can I tell ANT to copy everything in AAA.JAR that matches, say, _*Stub.class and copy only those files into BBB.JAR (also, maintaining the same directory/package structure)?

任何想法或指示将不胜感激！谢谢，

Any ideas or pointers would be GREATLY appreciated! Thanks,

罗布

推荐答案

好的——回答我自己的问题——这出奇的简单.抱歉我问了.

Ok -- answering my own question -- that was surprisingly easy. Sorry I asked.

<unzip src="AAA.JAR" dest="./temp">
  <patternset>
    <include name="**/_*Stub.class" />
  </patternset>
</unzip>

<zip destfile="BBB.JAR" basedir="./temp" />

谢谢蚂蚁.
