[m2e-users] New weird errors in pom.xml this morning, had to restart Eclipse to fix it
|
This morning I noticed that my Maven projects are giving me weird errors in my pom.xml file. Two of them I hadn't changed recently, but the other I worked on yesterday, and it was fine. I didn't change anything in the pom or the project config.
I'm using STS 2.8.1 (essentially Indigo), with m2e 1.0.100.20110804-1717.
In my pom.xml, the Problems view lists the following 4 problems:
--------------
Line: 1; Description: null
Line: 11; Description: Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (execution: default-compile, phase: compile)
Line: 11; Description: Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (execution: default-testCompile, phase: test-compile)
Line: 11; Description: Project configurator "com.springsource.sts.ide.maven.core.springProjectConfigurator" is not available. To enable full functionality, install the project configurator and run Maven->Update Project Configuration.
--------------
The description for that first one really is "null". That's what it says in the Problems view. Line 11 is just the first "plugin" element, for the "maven-compiler-plugin". There's nothing surprising here. It was fine yesterday, and the pom wasn't changed. I have no idea what "the project configurator" is, but I think it's likely I already have it.
I've tried doing "Update Project Configuration", but it doesn't make any difference.
I'm getting almost exactly the same errors on another unrelated Maven project. On that one I tried removing the maven nature and then re-adding it. No difference.
I also tried running the Maven build for these two projects, and they both completed successfully.
I tried doing a "Project Clean". No difference.
I tried removing the 4 error messages from the Problems view and doing a "Project Clean". The 4 errors reappeared.
Finally, I exited and restarted Eclipse. This fixed the problem. Everything's fine now. However, exiting and restarting Eclipse is something I avoid. It takes perhaps 15-20 MINUTES to completely finish restarting on my Centrino2 Dell laptop.
