我試圖通過在JavaFX中製作的GUI啓動命令行應用程序。 當我在我的IDE中運行該程序時，它一切正常，但是當我嘗試通過雙擊編譯的.jar文件運行它時，它不會。Java - 從終端運行jar但雙擊休息功能
我已經知道，這可能是因爲PATH或類路徑或工作目錄或類似的東西不同於從終端運行時。

編輯：忘了提及，雙擊Windows的作品完美。編輯2：**我剛剛發現了什麼是「真正」的問題。如果你運行終端或bash腳本，這是echo $ PATH的結果：'/Users/Vermeulen/.jenv/shims:/opt/local/bin:/opt/local/sbin：/ Library/Frameworks/Python.framework/VE rsions/3.5 /斌：在/ usr/local/bin目錄：在/ usr/bin中：/ bin中：/ usr/sbin目錄：/ sbin目錄：在/ usr/local/bin目錄中：/ opt/x11/bin：/ usr/X11/bi'，當你雙擊jar時echo $ PATH的結果是：'/ usr/bin：/ bin：/ usr/sbin：/ sbin'**
通常，您應該始終爲Java程序提供.bat/.sh啓動腳本。 – Alexiy
我想我必須這麼做，因爲我不知道如何解決$ PATH問題。謝謝您的回答。 – ACCESScoPezz
