The problem:
`target/classes` directory should be either empty/missing or it should contain
java classes to make spotbugs work.
On github it works well as an empty checkout is tested. But locally it's
possible that a dummy classpath file is created under
`hadoop-hdds/target/classes` which breaks spotbug local execution.
The solution is easy: execute the classpath descriptor generation only if
`src/main/java` dir exists.
