Project configurator "org.jboss.tools.maven.apt.MavenCompilerAptProjectConfigurator" is not available
===

i am using **maven 2** and **eclipse helios**, and after installing the plugin **M2E 1.0** from here:

http://download.eclipse.org/technology/m2e/releases

i am getting the following error in eclipse:

    Project configurator "org.jboss.tools.maven.apt.MavenCompilerAptProjectConfigurator" is not available. 
    To enable full functionality, install the project configurator and run Maven->Update Project Configuration

also i am getting the following two errors:

    Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile 
    (execution: default-compile, phase: compile)
    
    Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile 
    (execution: default-testCompile, phase: test-compile)
