【无法解决】用Procyon导出某个jar包中指定的包名的代码

导出 crifan 54浏览 0评论
折腾:
【已解决】用Procyon命令行去从jar包导出java源代码
期间,再继续研究看看,如何直接导出指定的类:
即,希望从此处的:
com.huili.readingclub8825612-dex2jar.jar
能导出,其中指定的类:
com.huili.readingclub
-》而无需导出其他无用的,Android自带的库的代码了。
-》以便于提高导出速度。
继续参考:

0.5.30是2015年的,也是够老旧的版本了。

【总结】
此处看来是,不论哪个版本
  • mac中brew install出来的0.5.30的
  • 还是最新的直接下载到的jar包0.5.34
的procyon-decompiler,目前都是不支持
procyon(1) — procyon-decompiler — Debian stretch — Debian Manpages
的debian系统的工具procyon的语法
Decompile a single class from a jar:
$ CLASSPATH=myJar.jar procyon com.example.Foo
的。
