[ImageJ-devel] Eclipse hickup with enforcer rules of pom-fiji > 7.2.0

Hard for me to follow if you guys have solved this one or now but, Re: the potential of a maven version discrepancy between Eclipse and the CLI, it looks like you can check the install/version of maven that eclipse is using by going to the menu Eclipse > Preferences > Maven > Installations 

Only now just found this now and I see it is a different install than I use at the command line. Looks like you can point it to a particular install though to make sure they are the same.

Cheers,

Jay
