5 months ago Please find the message.log (see https://stackoverflow.com/questions/50462124/netbeans-where-to-find-the-ide-log) and attach it here. Your answer to "How to reproduce" is extremely unhelpful, the meaning of that question is: What does another developer need to do, to see the problem, starting with a clean NetBeans installation.
You can run NetBeans with a temporary empty userdir by invoking it as path_to_netbeans/bin/netbeans64.exe --userdir c:/temp/test. That way you can rule out misconfiguration of your IDE.
Apache NetBeans version
Apache NetBeans 20
What happened
Evey project I create has been throwing an error that Hamcrest libraries are missing, even though they are in the project library collection. "A java.lang.IllegalArgumentException has occurred."
Language / Project Type / NetBeans Component
Java Ant Application
How to reproduce
There is nothing to reproduce the error, the whole library is not being read by the IDE.
Did this work correctly in an earlier version?
No / Don't know
Operating System
Windows
JDK
JDK 21
Apache NetBeans packaging
Apache NetBeans provided installer
Anything else
