Module compiles, but editor shows compilation issues 

answered Arnoud Glimmerveen Created April 18, 2014 11:01  

Since I reorganized my environment today (New project, clean checkout of code from SVN), I have not been able to edit code without the editor showing 'compilation issues' for code that does actually compile.

I have a bunch of Maven modules that compile file using Maven (both from command line and from IDEA) and compilation from IDEA (Build -> Compile/Make) works as well.
But when opening one of the java files, all referenced types that do not originate from my Maven module itself (types from dependencies) are marked as compilation problems ('Cannot resolve symbol XYZ') in the editor. Code completion only reveals types from dependencies when I type the fully qualified name, but a type entered this way is still displayed as a compilation problem (red).

I have no clue what is going wrong here. Has any encountered this behaviour before? I am using IDEA 13.1.1.

Try invalidating your caches and restarting IDEA (File > Invalidate Cache). Wait for IDEA to re-index your project (Status indicator on lower right status bar). The caches will sometimes become corrupted. This is most likely to occur upon reorganizing a project as you mentioned you did.

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.

•   no ..still facing the same issue. maven settings.xml is pointing to correct maven settings.xml  – yugi  Jun 1, 2018 at 8:39
• 1 As a last resort, can you try to create your project anew? (e.g. by coping your project folder without the *iml files / .idea folder) and see if you get the same errors. If you don't it's your (intelliJ) project's config. If you still have the issue, it's perhaps an IntelliJ issue itself. Try to see if there is an update or try the EAP. and/or disable all plugins.  – BitfullByte  Jun 1, 2018 at 9:04
•   yeah .. i will try this  – yugi  Jun 1, 2018 at 9:22

After this, if you are asked to override .iml (idea files), you can override them. 

This should hopefully solve your problem.

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
