Hi, I'm currently trying to build Hadoop 3.3.6 from the rel/release-3.3.6 tag (commit: 1be78238728da9266a4f88195058f08fd012bf9c). I have used the docker-based environment, using `./start-build-env.sh`. In the shell I issue `mvn package -Pdist -DskipTests` and after a while I get an error message
``` [INFO] --- maven-compiler-plugin:3.1:testCompile (default-testCompile) @ hadoop-common --- [INFO] Compiling 717 source files to /home/ubuntu/hadoop/hadoop-common-project/hadoop-common/target/test-classes [INFO] ------------------------------------------------------------- [WARNING] COMPILATION WARNING : [INFO] ------------------------------------------------------------- [WARNING] /home/ubuntu/hadoop/hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/security/ssl/KeyStoreTestUtil.java: Some input files use or override a deprecated API.

I tried to look for similar errors in the issue mailing list but I have not found anything. Am I doing anything wrong here? Many thanks Enrico
