BuildTools 1.17 has introduced extra mappings for "org.spigotmc:minecraft-sever", and during the process of maven install, pom file generated in "org/spigotmc/minecraft-server/1.17-R0.1-SNAPSHOT" contains an extra "packaging" field.

 When trying to use that artifact as dependency in gradle, error shows up on gradle sync

Could not find org.spigotmc:minecraft-server:1.17-R0.1-SNAPSHOT

 Manual modification of "minecraft-server-1.17-R0.1-SNAPSHOT.pom" can fix this issue, but I think it is better to fix this by disabling pom generation when installing mapping files.
