I have shifted my project to a different machine, copied all my maven libraries from old machine to new machine, did Right click on my project >> Maven >> Update Project. And then built my project. In addition to this, I have also done this one step which is shown in screenshot. And that's all it worked!!
Go to Window --> Preferences --> Maven --> User Setting, make sure you have these settings..
Also Right click on your project --> Properties --> Maven, and make sure you have the path here to maven repository..
