今天打開IDEA時，出現了“Unable to save settings Failed to save settings”異常，百度了一下，發現大部分都是說卸載“identifier Highlighter”插件，但是我并沒有安裝這個插件，所以在翻找了好久之后，終于是解決了問題，在此下一下我的解決經驗。
IDEA這個報錯翻譯過來就是：“保存設置失敗”，至于是為什么失敗，并沒有在此處說明，但是IDEA把具體原因放到了他的日志文件中，所以只要我們找到了日志文件，那么就可以對癥下藥，解決問題！
1.尋找日志文件
C盤—User(用戶)—.IntelliJIdea文件夾—system—log—idea.log
注意：如果電腦有多個用戶，那么就是在你當前用戶下的.IntelliJIdea文件夾中
2.找到報錯
打開idea.log文件，從最下面開始翻，找到最新的報錯信息，那就是你遇到的真正問題，找到之后，翻譯一下，基本就知道問題在哪兒了
下面列舉幾個報錯的原因
1.這個報錯是沒有寫入文件的權限，再看后面的“C:\Users\.idea”，說明是沒有C盤的寫入權限
2.此處最下面可以看到“ Cannot save scheme workspace/Jetty Server”，說明是jetty的配置有問題(此處代碼轉載自https://blog.csdn.net/yjw123456/article/details/78547552/)
