Question

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 : [INFO] ------------------------------------------------------------- [ERROR] No compiler is provided in this environment.

Answer 1

Follow these steps to solve this error:

• On Eclipse IDE, go to Window > Preferences > Java > Installed JREs > and verify your installed JREs. Check whether you have an entry with a JDK, if not create one.

• Choose the Execution Env. Click OK

• After this you need to Right-Click on Project -> Maven -> Update Project

 

If this doesn't work then Additionally, you may have to adjust Maven JRE which is as follows. 

Goto Run -> Run Configurations, choosing the Maven Build you were running (from the left panel). Next, click the JRE tab and choose the option Workspace default JRE
