Shawn Heisey commented on LUCENE-8189:
--------------------------------------
bq. add a check for the exact ANT version
Good idea. Have it check the versions of all relevant tools and fail with a
helpful message if they are outside of the range that we consider acceptable.
> Build fails with ant version 1.10.x
