Could be. Can you try removing the JRE and reinstalling the JDK?
I think that JAVA_HOME is pointing to the JRE, which isn't enough for
maven. If you don't want to remove the JRE, you can try to change
JAVA_HOME to point to the JDK.
  Sachin, I did add the bin dir. of mvn install to the
Path variable but
 it does not seem to help.
 mvn --version also gives the same error as mvn install:
 ERROR: JAVA_HOME not found in your environment.
 Please set the JAVA_HOME variable in your environment to match the
 location of your Java installation
 This is the error I get. 
I got past this error by manually entering the path to java in
maven\bin\mvn.bat
