無法創建可運行的JAR文件（Eclipse）
[英]Unable to create Runnable JAR file ( Eclipse )
問題描述
我已經在eclipse中制作了一個小游戲，但是無法導出它。 每當我嘗試執行此操作時，都沒有啟動配置，經過一段時間的研究，我發現了如何創建配置，但是現在我得到了錯誤
“ JAR導出已完成並顯示警告。請參閱詳細信息以獲取更多信息。導出時已編譯警告：space / src / space / main.java Jar導出已完成，並出現問題。請參見詳細信息以獲取其他信息。在給定的啟動配置中找不到主要方法。”
我當前正在使用兩個類文件。 我已經讀過它，可能是因為它不是GUI，但是它不使用控制台並在窗口中顯示，所以我可能很困惑。 包裝空間；

Next主要由一個循環組成，但是我還沒有實現。

在您的情況下，您在使用applet時不需要主要方法。
您可以嘗試執行以下操作：
- 從gameloop中刪除包“ space”或將其添加到主類
編譯代碼
javac gameloop.java javac -cp。 main.java
以小程序的形式運行代碼
appletviewer main.class
確保所有文件都放置到位（wall.png，floor.png等）
如果您希望能夠通過java命令運行main.java ，則需要在其中添加公共靜態void main（String [] arg） ，並確保創建main對象並調用它的init方法。
