在编辑器中显示 IntelliJ-idea 中的编译错误

Question

Showing compile error in IntelliJ-idea editor.

mvn clean install 

When run it will build successfully and run code normally. But in editor its unable to resolve those import. Some of the import is showing correctly some of the import it's showing error like Blow

and actually, the dependency is present in maven dependency list

In the editor, it showing full of error

I modified build settings, deleted repo, updated maven to the latest version, updated the IntelliJ and tried other suggestion in StackOverflow, still no solution for this problem.

Answer 1

Try:

• file > invalidate caches / restart
• maven tool window -> re-import / refresh:
• check maven settings of IntelliJ: does it point to the same settings.xml and repository as the maven from the command line? IntelliJ is shipped with it's internal maven and might use different settings / repo than your plain maven from the command line.

Answer 2

I believe this issue is related to the way we open this project in IntelliJ Idea as mvn clean install is working fine for you.

While opening the project in IntelliJ, you should open maven project like this:

• New -> Project from Existing Sources -> Select Project -> Import from External Model (Select maven here)
• After this, if you are asked to override .iml (idea files), you can override them.

This should hopefully solve your problem.

Answer 3

You can invalidate the cache

file -> invalidate caches and restart 

selecting first two options shown in invalidate cache has worked for, also you might get compile time error in already opened file so, try closing/opening these already opened files which are showing errors.

1. Clear file system cache and Local History : remove the virtual file system cache together with the information stored in Local History.

    This action might be helpful for troubleshooting purposes when the usual cache invalidation is not enough to solve the problem.

   2. Ask before downloading new shared indexes : show a notification prompting you to download new shared indexes as they become available.

    Enabling this option also updates your settings for shared project indexes in Settings/ Preferences | Tools | Shared Indexes.

   3. Clear downloaded shared indexes : remove the downloaded shared index files.

Answer 4

If it helps, I also had to bump up the heap size for compiler to get past this issue.

Answer 5

尝试删除项目下的 .idea 文件夹，完全关闭项目并重新导入，它对我有用。

Answer 6

I resolved this issue by deleting the local maven repository and restoring the default setting of Intellij

1. Go to File --> Manage IDE Settings --> Restore Default Settings
2. Go to File --> Settings --> Build, Execution, Deployment --> Build Tools --> Maven --> Get the Local repository path and delete it.
3. Open Intellij --> open project --> Go to Terminal --> mvn clean install --> error will disappear after build success

Answer 7

Go to project and do reimport.
