vscode中的java插件 Language Support for Java by RedHat 正常初始化之后,vscode右下角是這樣的
是一個大拇指的狀態,這時main方法和TestCase方法上都會出現 Run|Debug 快捷鏈接,可以方便的進行測試
terminal中會輸出如下類似信息

有時會出現java插件初始化異常的情況,現象是大拇指位置一直在轉圈,而且沒有任何報錯
這時可以進行如下操作:
- 設置java.trace.server=verbose
設置
- 打開developer tools (打開命令面板后輸入 developer tools)
Plug-in org.eclipse.jdt.ls.core was unable to load class org.eclipse.jdt.ls.core.internal.LanguageServero
然后看到如下報錯:
Plug-in org.eclipse.jdt.ls.core was unable to load class org.eclipse.jdt.ls.core.internal.LanguageServero
有一種方法可以解決,把代碼工程拷貝到其他目錄再打開,原因不詳.
