I am trying to create an adapter for RQM v4.0.3 - Selenium Integration  and I am receiving Could not find or load main class com.ibm.rqm.adapter.commandline.QMCommandLineAdapter complete error message is pasted below

I have verified below points.
1.       Java version on machine.
2.       JUnit Selenium adapter version with RQM. (Please refer screenshots for versions).
3.       Environment variable path for JAVA_Home and Path.
4.       Followed each step mentioned in the user guide(https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&sqi=2&ved=0CBwQFjAA&url=https%3A%2F%2Fwww.ibm.com%2Fdeveloperworks%2Fcommunity%2Ffiles%2Fform%2Fanonymous%2Fapi%2Flibrary%2Fa82c60c3-d3d9-4444-9f9f-63678cf12c17%2Fdocument%2F2d6c076b-1cb5-41c9-9365-22185c44bb95%2Fmedia%2FRQM_Selenium_Integration_Approach.pdf&ei=Ks6PVPrkF8-nuQTLo4HYAQ&usg=AFQjCNE_RU7qo0PT1LVeMDzxFFFcv2gybQ&bvm=bv.81828268,d.c2E)
