Hi Brahma, I tried your way. I think it works! Although there is some other issue coming up (which I need fix later), the build process doesn't complain for too long command line any more.
My previous default maverepo is C:\Users\Ping\.m2\repository and now is changed to D:\mavenrepo. Yes, I did read you and Arun's post in that link. Yes, Arun said it worked but didn't mention whether or not he ended up with using a shorter path. On my situation, I thought the error is probably due to "too long classpath" as there are so many dependencies instead of "too long path" as the default path is only 3 levels longer. But the classpath is long and occupies many lines on my screen. Now as I take your suggestion. It works. Many thanks for your quick response and help!!
