Not Able to run Activiti about activitiinaction HOT 1 OPEN

Sample Problem for me. Whenever I try to import the bpmn-examples in Eclipse 
Indigo as a Maven Project I get the following error:

'Cannot complete the install because one or more required items could not be 
found.
  Software being installed: m2e connector for build-helper-maven-plugin 0.15.0.201207090124 (org.sonatype.m2e.buildhelper.feature.feature.group 0.15.0.201207090124)
  Missing requirement: m2e connector for build-helper-maven-plugin 0.15.0.201207090124 (org.sonatype.m2e.buildhelper 0.15.0.201207090124) requires 'bundle org.eclipse.m2e.jdt [1.1.0,2.0.0)' but it could not be found
  Cannot satisfy dependency:

    To: org.sonatype.m2e.buildhelper [0.15.0.201207090124]'

I also could not convert the bpmn-examples into a Maven project since it throws 
many errors in pom.xml file. Please help. It is very difficult to follow the 
book without the working examples.
