Eclipse loops endlessly: Invoking 'Maven Project Builder'

eclipse maven m2eclipse

Ugh! My Eclipse is stuck in an endless loop:

  • No operations to display at this time
  • Refreshing Workspace Building
  • Workspace. Invoking 'Maven Project Builder' on /MobileWebApp

The building workspace never gets past 58%.

Details:

Google's GWT provides a sample app MobileWebApp. They suggest adding it to Eclipse via File > Import > Checkout Maven projects from SCM.

I followed the instructions in this blog for adding the plugins for m2e, subclipse, and the m2e-subclipse connector.

After installing the plugins, I imported the sample project via File > Import > Checkout Maven projects from SCM and this URL.

The import seemed to complete ok and Eclipse doesn't display any markers. But now I have this endless refreshing and building and have no clue what is causing it or how to fix it.

Versions:

  • Eclipse Indigo 3.7
  • m2e 1.0.100
  • m2e connector for build-helper-maven-plugin 0.14
  • Maven SCM handler for Subclipse 0.13
  • Subclipse 1.6.18
  • Subclipse Client Adapter 1.6.12

Any advice is greatly appreciated.

I opened my module's .project file. There were two entries:

<buildCommand>
  <name>org.maven.ide.eclipse.maven2Builder</name>
</buildCommand>
<buildCommand>
  <name>org.eclipse.m2e.core.maven2Builder</name>
</buildCommand>

I removed org.eclipse.m2e.core.maven2Builder entry and it magically fixed the problem.

No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

I'm compiling a project in Eclipse using m2eclipse. I set the JDK path in Eclipse like this: Windows-->preferences-->installed jres--> jdk1.7.xx path But this is showing an error [ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] …
