我尝试从终端创建文件，
jar -cvfm Bard.jar ../Bard/out/production/Bard/META-INF/MANIFEST.MF ../Bard/out/production/Bard/*.class
但是这会在jar存档中创建相同的文件目的地，并给我这个例外
adding: Bard/out/production/Bard/Main.class(in = 868) (out= 555)
(deflated 36%)
adding: Bard/out/production/Bard/WordProcessor.class(in = 9725) (out=
4666)(deflated 52%)
Error: Could not find or load main class Main
我该如何正确地做到这一点？
