LSP does not work due to failing build

[alephonea]

After setting up metals LSP plugin for Scala LSP, importing project fails due to failed build:
2025.08.27 18:04:19 ERROR Maven command failed: /usr/lib/jvm/java-17-openjdk-amd64/bin/java -Dfile.encoding=UTF-8 -Dmaven.multiModuleProjectDirectory=/media/data/repo/spark-rapids -Dmaven.home=/tmp/metals1289507670246448485 -cp /tmp/metals1289507670246448485/maven-wrapper.jar org.apache.maven.wrapper.MavenWrapperMain generate-sources ch.epfl.scala:bloop-maven-plugin:2.0.1:bloopInstall -DdownloadSources=true

maven phase bloopInstall fails similarly:

$ mvn -Dbuildver=356 install -DbloopInstall
[ERROR] Failed to execute goal org.apache.rat:apache-rat-plugin:0.13:check (default) on project rapids-4-spark-parent_2.12: Too many files with unapproved license: 1 See RAT report in: /media/data/repo/spark-rapids/target/spark356/rat.txt -> [Help 1]

For the first error, we currently require the install phase for the bloopInstall profile to work in this project https://github.com/NVIDIA/spark-rapids/blob/branch-25.10/CONTRIBUTING.md#bloop-build-server

For the second error, you might have some extra files in the local repo making the license header check fail. The check includes files that are not registered in SCM. If you add -Drat.skip to the command line you should get past this error without deleting those files.
