有什麼方法可以找出.class文件的構建路徑嗎？

Question

有什麼方法可以找到原始構建路徑或java文件編譯的包？

當我抽出一個小程序，並嘗試使用主類運行它，我得到這個...

Exception in thread "main" java.lang.NoClassDefFoundError: RunTimeFiles/ 
wrong name: client) 
     at java.lang.ClassLoader.defineClass1(Native Method) 
     at java.lang.ClassLoader.defineClass(Unknown Source) 
     at java.security.SecureClassLoader.defineClass(Unknown Source) 
     at java.net.URLClassLoader.defineClass(Unknown Source) 
     at java.net.URLClassLoader.access$100(Unknown Source)

     at java.lang.ClassLoader.loadClass(Unknown Source) 
     at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source)

我已經讀了它，顯然是因爲該文件的路徑是不同的當它們被編譯時，我有什麼方法可以找到它？

當我解壓在默認目錄中的類文件，當然文件被混淆，但我嘗試使用.bat文件來運行的主類，我得到這樣的：提前

檢查您的manifest.mf文件，在這些文件中有要執行的主類的名稱。
