Maven install plugin with depedency packaging - maven

Question

I have Project A and Project B. ProjectB just has only proprietary jars or third party libs that ProjectA needs which cannot be found in maven repository. I intended to package all the related ( grouping dependencies) jars of Project B into one/more jar files. Question is, how do I install these jars and shade/assemble them in to one jar at the same time using POM. I am getting proprietary jars installed separately but I cannot get them packaged them in to one jar. M2 eclipse is also not helping much , so I decide to use mvn commands inside eclipse. What is the best practice to do this?. I think shading them since I want to use these dependencies in other projects as well.Can I install and shade/assemble jars( logically group the related dependencies in to one jar) at the time using POM?.
I followed this( from stack over flow forum) , it did not work- as this is creating one project jar which doesn't have anything + proprietary jars separately but not shading all jars in to one. I want them installed and combined in to one jar at the same time.
