--------------------------------------------------
Summary: multiple versions of JUnit/Hamcrest cause test failures
to fail with NoSuchMethodError
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
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:
