Nothing will happen

For your Eclipse, you use always use JDK. You can't use JRE to compile your Java applications.

That's not true with Eclipse; Eclipse contains its own built-in Java compiler, it does not use the Java compiler supplied with the JDK.

Maven needs a JDK to run. In Eclipse, look at Window / Preferences / Java / Installed JREs. Make sure both your JRE and JDK are registered there.

Sounds like something which would sit better on another forum. Moving to "IDEs".

Aruna, each line in eclipse.ini should hold only one token, thus change it to two lines. Also, I think you need to specify the full path to either the java.exe or jvm.dll:
