今天打开IDEA时，出现了Unable to save settings Failed to save settings的异常。百度了一下，发现大部分问题都是说卸载identifier Highlighter插件，但我并没有安装这个插件，所以继续搜索。

今天打开IDEA时，出现了“Unable to save settings Failed to save settings”异常，百度了一下，发现大部分都是说卸载“identifier Highlighter”插件，但是我并没有安装这个插件，所以在翻找了好久之后，终于是解决了问题，在此下一下我的解决经验。

IDEA这个报错翻译过来就是：“保存设置失败”，至于是为什么失败，并没有在此处说明，但是IDEA把具体原因放到了他的日志文件中，所以只要我们找到了日志文件，那么就可以对症下药，解决问题！

1.寻找日志文件

C盘—User(用户)—.IntelliJIdea文件夹—system—log—idea.log

注意：如果电脑有多个用户，那么就是在你当前用户下的.IntelliJIdea文件夹中

2.找到报错

打开idea.log文件，从最下面开始翻，找到最新的报错信息，那就是你遇到的真正问题，找到之后，翻译一下，基本就知道问题在哪儿了

下面列举几个报错的原因

1.这个报错是没有写入文件的权限，再看后面的“C:\Users\.idea”，说明是没有C盘的写入权限

2.此处最下面可以看到“Cannot save scheme workspace/Jetty Server”，说明是jetty的配置有问题(此处代码转载自blog.csdn.net/yjw123456/article/details/78547552/)
