Sean Busbey commented on HADOOP-11804:
--------------------------------------
It would be unwise for us to add a profile to selectively have folks opt-in to
producing the shaded artifacts. In Apache HBase that's been a source of build
errors where folks end up with empty jars in nexus repos. Here in Hadoop we've
been incrementally adding pre-commit coverage for profiles as folks realize
they exist and aren't known to pre-commit.
If you don't want to build the shaded artifacts, you can either run just the
{{test}} goal, or ask maven to only build the module(s) you care about and any
modules needed to build those module(s). e.g. {{mvn --projects
:hadoop-yarn-project --also-make package}} or {{mvn --projects
:hadoop-yarn-ui,:hadoop-yarn-server-timelineservice --also-make package}}. (You
could also ask it to make modules that depend on your changed module with
{{--also-make-dependents}} but that will almost certainly lead to building the
shaded artifacts.)
We could add a profile to selectively opt-out of creating the shaded artifacts,
but the above maven commands are how one would do it "the maven way".
