I noticed that there is some Language Server initialization flashing for pom.xml as well. Wondering if this is related.

It seems that the builder is jumping back an forth between those open two projects. One is a pom packaging type and the other one is a taker-maven-plugin packaging type. It almost looks like the builder is caught in a cycle.

After increasing the memory I let it ran last night to find it still building this afternoon. :) FWIW, a brief test last night and it looks like my 2019-09 is showing the same issue. Granted, I haven't worked with the Takari plug-ins in a while. However, even after uninstalling the Takari M2E plug-ins, it's still exposing that cycle issue.
