      3. click delete installer
      4. move the (empty) maven to the top of the list of maven installations

      my hudson.tasks.Maven.xml looks like this:
      <?xml version='1.0' encoding='UTF-8'?>
      <hudson.tasks.Maven_-DescriptorImpl>
      <helpRedirect/>
      <installations>
      <hudson.tasks.Maven_-MavenInstallation>
      <properties>
      <hudson.tools.InstallSourceProperty>
      <installers/>
      </hudson.tools.InstallSourceProperty>
      </properties>
      </hudson.tasks.Maven_-MavenInstallation>
      <hudson.tasks.Maven_-MavenInstallation>
      <name>/cvsroot/maven/maven-bin/maven-2.0.11 (depreciated - for Java 1.4 only)</name>
      <home>/var/hudson/tools/maven-bin/maven-2.0.11</home>
      <properties/>
      </hudson.tasks.Maven_-MavenInstallation>
      <hudson.tasks.Maven_-MavenInstallation>
      <name>/cvsroot/maven/maven-bin/maven-2.2.1 (Java 1.5+ required)</name>
      <home>/var/hudson/tools/maven-bin/maven-2.2.1</home>
      <properties/>
      </hudson.tasks.Maven_-MavenInstallation>
      <hudson.tasks.Maven_-MavenInstallation>
      <name>/cvsroot/maven/maven-bin/maven-3.0.x</name>
      <home>/var/hudson/tools/maven-bin/maven-3.0.x</home>
      <properties/>
      </hudson.tasks.Maven_-MavenInstallation>
      </installations>
      </hudson.tasks.Maven_-DescriptorImpl>

      the fix is simple: just delete the empty maven configuration
