Hi, JAVA_HOME points to jdk installation directory. JRE_HOME points to jre installation directory. I too have both installed and variables set. Try removing JRE_HOME for a change and see if this works. Also do the following: delete existing mvn folder. unzip mvn2.1 snapshot zip available on dev.xwiki in c folder. You can add the path to mvn bin in your system path. Then try mvn -version I have been building xwiki from source for quiet some time on windows and it works fine. If this still does not work you can connect me on sachin_mittal on skype and I would try to help you with the same. Thanks Sachin ----------------------------------------------------------------------

Yes, I have both JDK and JRE installed in the same location. (is that a problem?) 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.

Thanks
