'Eclipse showing false-positive missing include in xsl problems after upgrading to 2021-12
In our legacy maven project are several hundred XSL problems after I upgraded our team-wide used Eclipse Neon to Eclipse 2021-12 (4.22). Due to the upgrade, I also had to upgrade some modules such as TestNG (6.8.21 -> 7.3.0) and the maven-war-plugin (2.2 -> 3.3.2).
The project builds without problems via Maven or our Jenkins server and also runs on all our applications environments (on JBoss servers).
However, if I start to setup our new Eclipse, the IDE shows these problems as shown (corporate file names censored).
I can provide more information on detailed matters on demand.
Q: Did anybody had a similar issue or knows how to correct this?
I appreciate every help given!
EDIT: I don't do anything fancy with the IDE. I simply download and unzip the Eclipse version, import my maven project and after validation, the errors just show up. And the same behaviour occurs with Eclipse 2021-03.
