### Description On `main` today, with Java 21 on a recent Arch Linux, if I run `./gradlew clean` then `./gradlew check`, all is good. It passes. But if I run `./gradlew check` again, I sometimes (not always -- might take another `./gradlew check`) get these false warnings about unreferenced license files: ``` WARNING: there were unreferenced files under license folder: - /s1/l/9x/lucene/licenses/antlr4-runtime-LICENSE-BSD.txt - /s1/l/9x/lucene/licenses/antlr4-runtime-NOTICE.txt - /s1/l/9x/lucene/licenses/asm-LICENSE-BSD_LIKE.txt - /s1/l/9x/lucene/licenses/asm-NOTICE.txt - /s1/l/9x/lucene/licenses/asm-commons-LICENSE-BSD_LIKE.txt - /s1/l/9x/lucene/licenses/asm-commons-NOTICE.txt - /s1/l/9x/lucene/licenses/assertj-core-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/assertj-core-NOTICE.txt - /s1/l/9x/lucene/licenses/commons-codec-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/commons-codec-NOTICE.txt - /s1/l/9x/lucene/licenses/commons-compress-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/commons-compress-NOTICE.txt - /s1/l/9x/lucene/licenses/commons-logging-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/commons-logging-NOTICE.txt - /s1/l/9x/lucene/licenses/hamcrest-LICENSE-BSD.txt - /s1/l/9x/lucene/licenses/hamcrest-NOTICE.txt - /s1/l/9x/lucene/licenses/httpclient-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/httpclient-NOTICE.txt - /s1/l/9x/lucene/licenses/httpcore-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/httpcore-NOTICE.txt - /s1/l/9x/lucene/licenses/icu4j-LICENSE-BSD_LIKE.txt - /s1/l/9x/lucene/licenses/icu4j-NOTICE.txt - /s1/l/9x/lucene/licenses/javax.servlet-LICENSE-CDDL.txt - /s1/l/9x/lucene/licenses/javax.servlet-NOTICE.txt - /s1/l/9x/lucene/licenses/jetty-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/jetty-NOTICE.txt - /s1/l/9x/lucene/licenses/jts-core-LICENSE-BSD_LIKE.txt - /s1/l/9x/lucene/licenses/jts-core-NOTICE.txt - /s1/l/9x/lucene/licenses/junit-LICENSE-CPL.txt - /s1/l/9x/lucene/licenses/junit-NOTICE.txt - /s1/l/9x/lucene/licenses/morfologik-fsa-LICENSE-BSD.txt - /s1/l/9x/lucene/licenses/morfologik-fsa-NOTICE.txt - /s1/l/9x/lucene/licenses/morfologik-polish-LICENSE-BSD.txt - /s1/l/9x/lucene/licenses/morfologik-polish-NOTICE.txt - /s1/l/9x/lucene/licenses/morfologik-stemming-LICENSE-BSD.txt - /s1/l/9x/lucene/licenses/morfologik-stemming-NOTICE.txt - /s1/l/9x/lucene/licenses/morfologik-ukrainian-search-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/morfologik-ukrainian-search-NOTICE.txt - /s1/l/9x/lucene/licenses/nekohtml-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/nekohtml-NOTICE.txt - /s1/l/9x/lucene/licenses/opennlp-tools-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/opennlp-tools-NOTICE.txt - /s1/l/9x/lucene/licenses/procfork-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/procfork-NOTICE.txt - /s1/l/9x/lucene/licenses/randomizedtesting-runner-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/randomizedtesting-runner-NOTICE.txt - /s1/l/9x/lucene/licenses/s2-geometry-library-java-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/s2-geometry-library-java-NOTICE.txt - /s1/l/9x/lucene/licenses/spatial4j-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/spatial4j-NOTICE.txt - /s1/l/9x/lucene/licenses/xercesImpl-LICENSE-ASL.txt - /s1/l/9x/lucene/licenses/xercesImpl-NOTICE.txt ``` It's sometimes a smaller set of (still false positive) warnings, which is also odd. For the longest time I've been assuming I'm doing something wrong :) But then I noticed @msokolov also sees this sometimes, so it's not just me. Does anyone else see these? [I also raised [this dev list discussion](https://lists.apache.org/thread/xgqb00w597z087fsf9sj2s7jq27y2llc) about it]. ### Version and environment details _No response_ -- This is an automated message from the Apache Git Service.
