Assembly jar doesn't get rebuilt on CLI changes

[fnothaft]

At least, this is what I'm seeing locally. I'm not exactly sure why this is, but it appears that the CLI jar gets rebuilt, but the shaded uberjar doesn't. @heuermh I've assigned this to you, because I think you're the best person to take this on.

I'm not able to replicate this.

Making a change to ADAMMain.scala changes the file size of the uberjar

$ mvn install
$ ls -ls /Users/heuermh/.m2/repository/org/bdgenomics/adam/adam-assembly_2.10/0.20.1-SNAPSHOT/adam-assembly_2.10-0.20.1-SNAPSHOT.jar
42332825 Nov  4 06:12 adam-assembly_2.10-0.20.1-SNAPSHOT.jar

// make change, then
$ mvn install
$ ls -ls /Users/heuermh/.m2/repository/org/bdgenomics/adam/adam-assembly_2.10/0.20.1-SNAPSHOT/adam-assembly_2.10-0.20.1-SNAPSHOT.jar

I will close this for now and reopen if I have this repro.
