Gabor Liptak commented on HADOOP-12048: --------------------------------------- OK, I found the error at: https://builds.apache.org/job/PreCommit-HADOOP-Build/7089/artifact/patchprocess/patchJavacWarnings.txt I do not see this locally so I need to identify the difference. > many undeclared used dependencies (and declared unused dependencies) > -------------------------------------------------------------------- > > Key: HADOOP-12048 > URL: https://issues.apache.org/jira/browse/HADOOP-12048 > Project: Hadoop Common > Issue Type: Bug > Components: build > Affects Versions: 3.0.0 > Reporter: Sangjin Lee > Assignee: Gabor Liptak > Attachments: HADOOP-12048.1.patch, HADOOP-12048.2.patch, > HADOOP-12048.3.patch, dependency-analysis.txt, hadoop-unused.txt > > > Currently there are numerous undeclared used dependencies and declared unused > dependencies in the hadoop projects. > Undeclared used dependencies are easier errors to correct, and correcting > them will lead to a better management of dependencies (enabling stricter > dependency frameworks down the road). > Declared unused dependencies are harder to resolve, as many may be legitimate > runtime dependencies. But fixing them would lead to smaller profiles for > hadoop projects. > We can do a one-time scan of dependency issues and fix them. However, in the > long run, it would be nice to be able to enforce those rules via maven > plug-in. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
