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


java eclipse maven java-7 m2eclipse

  1. On your Eclipse IDE, go into Window > Preferences > Java > Installed JREs > and check your installed JREs. You should have an entry with a JDK there.
  2. Select the Execution Env as show below. Click OK
  3. Then Right-Click on your Project -> Maven -> Update Project

Additionally, you may have to change Maven JRE (see @jlars62 answer) which is as follows. Goto Run -> Run Configurations, selecting the Maven Build I was running (from the left panel). Then, I clicked the JRE tab and selected the option Workspace default JRE

java eclipse maven java-7 m2eclipse

For me, it is exactly what the maven of eclipse complains

So, I press Edit button and change path to the JDK Folder, then clean project and everything starts to work

java eclipse maven java-7 m2eclipse

  1. Set the JAVA_HOME environment variable to the JDK root folder - required if you run command line or maven (mvn).
    • (Search google for JAVA_HOME for more info)
  2. In project properties in section Java Compiler select required JDK - if you run directly from eclipse
