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

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 :

As far as I might be concerned, nothing worked until I rolled out this improvement to my pom.xml


<build>

...

    <plugins>

    ...

        <plugin>

            <artifactId>maven-compiler-plugin</artifactId>

            <version>3.1</version>

            <configuration>

                <fork>true</fork>

                <executable>C:\Program Files\Java\jdk1.7.0_45\bin\javac.exe</executable>

            </configuration>

        </plugin>

    </plugins>

</build>

Different Notes

I could see that m2e was executing in a JRE, not the JDK. Nothing I did changed this, including adding this to the eclipse.ini:


-vm

C:\Program Files\Java\jdk1.7.0_45\bin\javaw.exe

If you are running the Maven command from cmd, make sure you set the jdk path before running the command. In my case, I have created a .bat file containing the following:

set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_60

start cmd.exe /k "cd c:\aem_proj\sis\aau"
