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

eclipsejavajava-7m2eclipsemaven

I'm compiling a project in Eclipse using m2eclipse. I set the JDK path in Eclipse like this:

Windows-->preferences-->installed jres--> jdk1.7.xx  path

But this is showing an error

[ERROR] COMPILATION ERROR :

Best Solution

  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
