2.44.0.BETA4 good
2.44.0       bad

[nedtwigg]

• Ah yes, this bug was introduced by Remove support for Eclipse CDT 10.7, new minimum is 11.0 #2373
• The solution is that we need to run the deploy build on JVM 17
• I'll do it right now

[nedtwigg]

Fixed in plugin-maven 2.44.1 and plugin-gradle 7.0.1
