[jira] [Commented] (NUTCH-2291) Fix mrunit dependencies

["Sebastian Nagel (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NUTCH-2291?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15358917#comment-15358917 ] 

Sebastian Nagel commented on NUTCH-2291:
----------------------------------------

Solution 1 is correct because the classifier is only a part of the jar file names in the [mrunit maven repo|http://central.maven.org/maven2/org/apache/mrunit/mrunit/1.1.0/]. It is not part of the POM file name which lets ant/ivy fail to retrieve mrunit's POM:
{noformat}
% ant -v -d resolve-test
...
[ivy:resolve] == resolving dependencies org.apache.nutch#nutch;working@vasyugan->org.apache.mrunit#mrunit;1.1.0 [test->default]
...
[ivy:resolve] HTTP response status: 404 url=http://repo1.maven.org/maven2/org/apache/mrunit/mrunit/1.1.0/mrunit-1.1.0-hadoop2.pom

> The Jenkins builds fail with a NoClassDefFoundError, see [build #3376 log|https://builds.apache.org/job/Nutch-trunk/3376/testReport/org.apache.nutch.crawl/TestCrawlDbStates/testCrawlDbStatTransitionInject/]. The missing class org/mockito/stubbing/Answer is part of build/test/lib/mockito-core-1.9.5.jar which was a dependency of mrunit (screenshot mrunit-deps-cached.png). After removing mrunit from my local ivy cache ({{rm -rf ~/.ivy2/cache/org.apache.mrunit/}} mrunit lost mockito as dependency (screenshot mrunit-deps-new.png) and the build failure is reproducible.
> I don't understand what triggered the loss of the transitive dependency: the upgrade to Hadoop 2.7.2 (NUTCH-2236) or the addition of {{maven:classifier="hadoop2"}} in commit [7956daee|https://git-wip-us.apache.org/repos/asf?p=nutch.git;a=commitdiff;h=7956daee8ac91180070f92949ecf99deae9b5ef0#patch2].
