Intellij IDEA崩溃，然后抛出错误[prolog中不允许内容]
Intellij IDEA崩溃，然后抛出错误[prolog中不允许内容]
提问于 2018-06-04 22:32:05
我正在使用IntelliJ Idea 2017.2。我的项目是一个由gradle构建的多模块项目。我已经给出了我的项目的构建。然后它就崩溃了。我再次启动了IntelliJ，并收到以下消息
Cannot load settings from file '.../config/options/code.style.schemes.xml': java.lang.AssertionError: Unexpected content storage modification File content will be recreated.然后我想，这可能是缓存相关的问题。然后，我重新启动了我的电脑，并执行了以下操作，
文件->无效缓存/重新启动
这一次，我得到了另一个错误。

at java.lang.Thread.run(Thread.java:745)我再次尝试clean/build这个项目。但是总是得到相同的错误。我搜索了throguh互联网，得到了以下问题。
i) SAX Error – Content is not allowed in prolog
ii) org.xml.sax.SAXParseException: Content is not allowed in prolog
但没那么走运。任何形式的帮助都将受到高度的感谢。

最后，我通过删除以下路径中的缓存文件夹解决了这个问题。
/home/<username>/.IntelliJIdea2017.2/system/caches (Linux)
/Users/<username>/.IntelliJIdea2017.2/system/caches (Mac)
C:\Users\<username>\.IntelliJIdea2017.2\system\caches (Windows)然后重新启动IntelliJ Idea，它工作得很好。
