Update the webui. It appears that the most recent BuildTools won’t operate unless you pretty much explicitly allocate 512MB of ram to the attempt.
The most recent update from a few days ago forces Java to do just this, so update and you’ll be on your way.

The download file “BuldingTools.jar” is bad - there is probably a bug here.
This page might help get it working for you
Yes, this post helped, namely replacing the corrupted BuildTools.jar file and replacing it with this one: https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar
