[ERROR] Failed to execute goal net.revelc.code:impsort-maven-plugin:1.10.0:sort (sort-imports) on project quarkus-websockets-next-deployment: Execution sort-imports of goal net.revelc.code:impsort-maven-plugin:1.10.0:sort failed: No enum constant com.github.javaparser.ParserConfiguration.LanguageLevel.JAVA_21
