Intellij IDEA 崩溃了，现在抛出一个错误

我在 Intellij IDEA 工作，但我的电脑死机了，所以我关掉了电脑。(长时间点击电源按钮)当我打开电脑，开始 IntelliJ IDEA 我有这个错误:

Cannot load settings from file 'C:\Users\user\.IdeaIC13\config\options\code.style.schemes.xml': java.lang.AssertionError: Unexpected content storage modification File content will be recreated

我关闭 IDEA 并重新开始，现在我没有前面的错误，但是当我打开我的项目时，我有这个错误:

我怎样才能解决这个问题？

Try File -> Invalidate Caches / Restart ...

I had the same problem, I removed the .idea directory and *.iml files and created the project again.

This answer works for both IntelliJ & AndroidStudio

If you cannot even open your project in IntelliJ[AndroidStudio]:

Close IntelliJ[AndroidStudio]
Go to the directory <your_home>/.IntelliJIdeaXX[.AndroidStudioXX]/system/cache

WHERE
- <your_home> is
  - Windows Users: C:\Users\<**Your User**>\ (or %USERPROFILE%)
  - Linux Users(Ubuntu), Mac: ~/
- XX is your IntelliJ version (This directory is "caches" in some versions.)
Remove all the files in the cache directory.
Then restart IntelliJ[AndroidStudio]

This has worked for me in the past.

I had the same problem when Windows crashed while Android Studio was on. I followed the following steps :-

Close Android Studio

Delete the .idea directory outside the project folder. Note : Do not delete the .idea directory inside the project folder. The .idea directory which you have to delete will contain some .iml files.

Restart Android Studio

tadaaa!!

I've found on several occasions that "Content is not allowed in prolog" presented when I had an XML file with leading spaces in front of the xml or doc type declarations at the start of the file.

I had the same symptoms, and was able to solve by closing the project and going through each of the XML files in the project ".idea" folder. In my case, I found that somehow a few hundred lines of leading whitespace had been added to the "workspace.xml" file. I removed the leading whitespace from the file, restarted IDEa and everything worked again.

If you are using a version control system like github, the easiest way is to erase your project folder, open IntelliJ and clone your repository again. Whatever file is corrupted is going to be gone and it should work fine again.

my solution

In project/.idea I have broken workspace.xml file. I just close Android Studio (Intellij IDEA), remove this file and start Android Studio.

All other approaches not work for me.

小开

In .idea folder, many XML files are present.
This error comes if some XML files are invalid.
First check workspace.xml file is valid or not.
If workspace.xml file is valid then check other file's.

In my case nothing of these worked.

But the final solution was very easy:

 rm -r ~/Library/Preferences/AndroidStudio[X.X]/codestyles/

小开

In my case, the project files under .idea got corrupted. If you have the project files checked in SVN or saved somewhere just remove all the local changes and revert to the previous working copy . Also rebuild the cache by File --> Invalidate Cache.

After that it is fixed for me. The "Error:Internal error: (org.jdom.input.JDOMParseException) " went away.

If your error happens when the IntelliJ idea starting. Just give a restart for the laptop. It will go after restarting. For me, this error happens per year like that.
