Error while using mvn -v in CMD after setting up Maven binaries on Windows

Question

I have installed the Maven apache-maven-3.3.9 binaries on Windows 10 and have set below variable as :

M2_HOME: 
C:\Program Files\apache-maven-3.3.9

M2: %M2_HOME%\bin

MAVEN_OPTS: Xms256m -Xmx512m

PATH: C:\Program Files\Java\jdk1.8.0_92\bin;%M2%

But when I run mvn -v in CMD, I get this error:

Error: Could not find or load main class Xms256m

I have already tried solution listed on this link

in the `MAVEN_OPTS` here above, did you miss an initial `-` while typing the question or effectively in your system? — A_Di-Matteo, Aug 27 '16 at 19:21

You have invalid environment variable MAVEN_OPTS (missing dash). It should be

-Xmx256m -Xmx512m

Thanks Man! It was silly mistake. It worked when corrected MAVEN_OPTS i.e. -Xms256m -Xmx512m – ShiwamP Aug 28 '16 at 17:22
