GWT + Maven + Error executing (org.bsc.maven:maven-processor-plugin:2.0.5:process:process:generate-sources)

问题

I use a clean eclipse 3.7, then added the Maven Integration for Eclipse from the Eclipse Marketplace. I also added WTP Integration and m2e connector for build-helper-maven-plugin from Windows -> Preferences -> Maven -> Discovery -> Open Catalog. I also added the Google Plugin for Eclipse.

I import an exising maven project that works fine with the command line when running command like: mvn compile gwt:compile or mvn gwt:run but in Eclipse I got this error:

Error executing (org.bsc.maven:maven-processor-plugin:2.0.5:process:process:generate-sources)   pom.xml /base   line 289    Maven Build Problem

Here is the related part of the pom file:

<plugin>
    <groupId>org.bsc.maven</groupId>
    <artifactId>maven-processor-plugin</artifactId>
    <version>2.0.5</version>

I managed to make it work by adding

-vm
C:\Program Files\Java\jdk1.6.0_26\jre\bin\server\jvm.dll

before -vmargs in eclipse.ini

As a rule of thumb you always need to change default JRE under Window->Preferences->Java->Installed JREs to JDK folder. In my case it was C:\Program Files\Java\jre6. I had to change it to C:\Program Files\Java\jdk1.6.0_31

I had the same problem on a Linux environment, I did the same thing Sydney did above but I still had to disable incremental build for maven processor, like this:

...
   <action>
      <execute>
        <runOnIncremental>false</runOnIncremental>
      </execute>
   </action>
...

This worked for me :)
