Description

mvn -f pom.ozone.xml -DskipTests -am -pl :hadoop-hdds-config clean package

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile (default-testCompile) on project hadoop-hdds-config: Compilation failure
[ERROR] Can't generate the config file from annotation: hadoop-hdds/config/target/test-classes/ozone-default-generated.xml

The root cause is that new Java (I guess it's 9+, but tried only on 10+) throws a different IOException subclass: NoSuchFileException instead of FileNotFoundException.
