> Key: DRILL-2130
> URL: https://issues.apache.org/jira/browse/DRILL-2130
> Project: Apache Drill
> Issue Type: Bug
> Components: Tools, Build & Test
> Reporter: Daniel Barclay (Drill/MapR)
> Assignee: Jacques Nadeau
> Priority: Minor
> Fix For: 1.0.0
>
>
> Apparently we have included multiple versions of JUnit and/or Hamcrest, and
> the new versions are not first on the class path.
> This means that when an assertThat call tries to report that an actual value
> mismatches an expected value, it dies with a NoSuchMethod error.
> That in turn means that what would have been an informative test-failure
> message turns into a confusing crash.
> It seems that something like this is happening: The unit test is calling the
> new version of some JUnit or Hamcrest class. That class is calling a method
> in another class (in Hamcrest), but the old version of the class gets loaded,
> so the call fails with NoSuchMethodError.
> Here's a sample stacktrace:
> java.lang.NoSuchMethodError:
> org.hamcrest.Matcher.describeMismatch(Ljava/lang/Object;Lorg/hamcrest/Description;)V
> at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:18)
