Steve Loughran commented on YARN-10992:
---------------------------------------
update.
# the maven pojo plugin generates code with the correct @Generated attribute
for that java version
# the plugin doesn't regenerate the .java classes if they are present
# if you have done a build with java11, you can't go back to java 8
fix
`
{code}
rm
hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/capacity/placement/schema/*
{code}
maybe the mvn clean operation should do this. If the classes were generated
into target/generated/java this would be automatic
> schema generation produces code which doesn't compile on java 11+
