Code completion not working inside pom.xml

I have found the following in the log file:

The error is disappearing, when I deactivate a profile which includes a subproject of the parent pom.
The profile definition is as follows:

<profile>
     <id>long-running-module</id>
     <modules>
           <module>long-running-module</module>
     </modules>
</profile>

The subproject is normally included as ready built jar because it needs long time to build.

Hello.

Can you attach your project here to let me find the problem?

If you cannot, then you can try the following hint on your side:
https://youtrack.jetbrains.com/issue/IDEA-120069#comment=27-667885

If the reference is not clear, one has to do the following:
1. Turn on the profile to include the problematic module. Probably get the error.
2. Select the module in the Project tool window.
3. F4 to open the module definition in Project Structure dialog.
4. Open Dependencies tab. See the list of "Maven: *" library entries.
5. One (or more) of these libraries contains a reference to pom.xml instead of jar in its definition. (You have to open every definition.)
You can try to remove that reference and reimport the module.

_If_ my supposition is correct (I do not see the actual project), this may help.

Alexander.

Hello Alexander,

since the project is closed source, giving you the code is not an option :(.

I have searched with your hints and found the following:

1. There were no libraries referencing a pom, but some errors in the artifact building process. => I've fixed them, enter is still not working in pom.xml files.
2. After that idea.log showed me the following stack trace:

3. I deactivated the AngularJS plugin, now everything is working again.

This looks very similar to https://youtrack.jetbrains.com/issue/WEB-12339
I've added the reference to this thread. Welcome to comment or add any information to that issue, if you like.

Alexander.
