What changes were proposed in this pull request?
In main pom.xml, for mvn_scalafmt plugin, I removed 'parameters' since it's invalid , and replace 'skip' with 'validateOnly' since 'skip' is invalid too.
Why are the changes needed?
I think we should not leave invalid items there in the pom.xml
I've contacted the author of mvn_scalafmt, Ciaran Kearney, to confirm if these 2 configuration items are no longer there since v 1.0.0, and he said: "That's correct. The command line parameters were removed by scalafmt itself a few versions ago and skip was replaced by validateOnly (which checks formatting without changing files."
Does this PR introduce any user-facing change?
Yes
How was this patch tested?
Run mvn-scalafmt_2.12:format locally via mvn.
