The error message is little bit confusing :"Null Pointer Exception in thread
main". What are you trying to build?
I did the following setup and its working fine for me:
M2_HOME = D:\apache-maven-2.0.9
JAVA_HOME = {Here the *JDK* Path] Remember Maven doesnt work properly with
JRE
PATH: %M2_HOME%/bin
Just run mvn --version and we are good to go.
If you are getting the version printed as 2.0.9, its correctly installed.
Also, if you can forward the apache link you are talking about (where you
got the example), I can look into that.
Thanks & Regards,
Ram
