Gradle - Compiling test cases

[Harlan]

Hello,

  I posted this yesterday to the Gradle forum and while some people have looked at the messages, no one has provided any suggestions.  I really need help to get this figured out, and soon.  Thank You!

The main application builds properly, but the test does not, even with the same set of jars defined. I'm not having a problem with the test itself, but rather that the jars are not being picked up in the path the test application. So far I haven't found anything that works.

I would appreciate any ideas or suggestions on getting the test application to compile correctly.

If you have any questions, please free to ask.

Thanks,

Harlan...

Did you add junit as a dependency in your gradle file?

something like this

dependencies {
    testCompile 'junit:junit:4.12'
}

[Harlan]

Hi Doug,
  Yes I did.  Here are the dependencies:

dependencies {
compile files("${System.properties['java.home']}/../lib/tools.jar")
compile 'org.apache.hadoop:hadoop-core:1.2.1'
compile 'org.apache.hive:hive-exec:2.0.0.2.3.5.0-81'

    testCompile files("${System.properties['java.home']}/../lib/tools.jar")
    testCompile 'junit:junit:4.8.2'
    testCompile 'org.apache.hadoop:hadoop-core:1.2.1'
    testCompile 'org.apache.hive:hive-exec:2.0.0.2.3.5.0-81'
}

Thanks,

Harlan...

I didn't check all of them but it looks like you're missing imports for some of those classes, such as Test and PrimitiveObjectInspectorFactory.
