bash command: search for class in file system of jars

bashsearchclassjararchive

提问by markdsievers

I'm wanting to recursively search my maven repository (an n folder deep heirachy of jars) for a specific class inside an unknown jar.

我想递归搜索我的 maven 存储库(一个 n 文件夹深层次的 jars)以查找未知 jar 中的特定类。

jar -tvf myJar.jar | grep ClassIWant.class works great for a known jar but I'm having problems piping/chaining bash commands to achieve a recursive search.

jar -tvf myJar.jar | grep ClassIWant.class 适用于已知的 jar,但我在管道/链接 bash 命令以实现递归搜索时遇到问题。

Any hints much appreciated.

任何提示非常感谢。
