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  p         


        

Answer 1

There are several options to specify.

Steps: Right on project in project explorer Go to Run-> Run Configuration -> Click Maven Build -> Click on your build config/or create a new config. You will see the window as the given snapshot below, click on JRE tab there.

You see you have 3 options 1) Workspace Default JRE 2)Execution Environment 3)Alternate JRE 1) Workspace Default JRE is set from 'Window' menu on the top -> Preferences -> Java -> Installed JREs -Here you can add your jdk 2) Execution Environment jdk can be set in pom.xml as mentioned by @ksnortum

    
        maven-compiler-plugin
        3.1
        
            true
            C:\Program Files\Java\jdk1.7.0_45\bin\javac.exe
        
    

3) Alternate JRE can be used to select a jdk from your directory
