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

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. Perhaps you are running on a JRE    rather than a JDK? [INFO] 1 error [INFO] ------------------------------------------------------------- [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 1.424s [INFO] Finished at: Tue Oct 29 15:21:01 IST 2013 [INFO] Final Memory: 5M/15M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-   plugin:3.1:compile (default-compile) on project TEST-WEB: Compilation failure [ERROR] No compiler is provided in this environment.

Answer 1

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
