FAQ
Prefer mvn test -DskipTests over mvn compile in test-patch.sh
-------------------------------------------------------------

Key: HADOOP-7589
URL: https://issues.apache.org/jira/browse/HADOOP-7589
Project: Hadoop Common
Issue Type: Bug
Components: build
Affects Versions: 0.23.0, 0.24.0
Reporter: Robert Joseph Evans
Assignee: Robert Joseph Evans
Fix For: 0.23.0, 0.24.0


I got a failure running test-patch with a clean .m2 directory.

To quote Alejandro:
{bq}
The reason for this failure is because of how Maven reactor/dependency
resolution works (IMO a bug).

Maven reactor/dependency resolution is smart enough to create the classpath
using the classes from all modules being built.

However, this smartness falls short just a bit. The dependencies are
resolved using the deepest maven phase used by current mvn invocation. If
you are doing 'mvn compile' you don't get to the test compile phase. This
means that the TEST classes are not resolved from the build but from the
cache/repo.

The solution is to run 'mvn test -DskipTests' instead 'mvn compile'. This
will include the TEST classes from the build.
{bq}

So this is to replace mvn compile in test-patch.sh with mvn test -DskipTests
