Matt Davis commented on LUCENE-5755:
------------------------------------
Gradle does use which ever junit version you specific. For example:
dependencies {
testCompile 'junit:junit:[4.10,)'
}
And because of the annotation RunWith(RandomizedRunner.class) and the
configured dependency to
'com.carrotsearch.randomizedtesting:randomizedtesting-runner:2.1.3' it uses the
RandomizedRunner from CarrotSearch. As I said before it also launches a
separate JVM. The actually issue is that it switches the system.out before
each test to capture the output. See the following classes:
https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/groovy/org/gradle/api/internal/tasks/testing/processors/CaptureTestOutputTestResultProcessor.java
https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/groovy/org/gradle/api/internal/tasks/testing/junit/JUnitTestClassProcessor.java
https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/groovy/org/gradle/api/internal/tasks/testing/junit/JULRedirector.java
https://github.com/gradle/gradle/blob/master/subprojects/core/src/main/groovy/org/gradle/logging/internal/DefaultStandardOutputRedirector.java
https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/groovy/org/gradle/api/internal/tasks/testing/junit/JUnitTestFramework.java
https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/groovy/org/gradle/api/tasks/testing/Test.java
If I disable the System.out check
(https://github.com/mdavis95/lucene-solr/commit/1b8798894e9f2c52b905eb5f259ef4108bb0b6d7),
and allow lucene benchmark to find alg files through a hack
(https://github.com/mdavis95/lucene-solr/commit/6be7c4a3b68fdc9ee749674d101a1c75b2f725be).
A whole lot of tests start to past.
For the lucene core I have 783 test successfull, 518 skipped, and 5 failures.
The only 5 that failed were in TestVirtualMethod.
java.lang.RuntimeException: Suite class
org.apache.lucene.util.TestVirtualMethod$TestClass1 should be public.

> Project: Lucene - Core
> Issue Type: Task
> Reporter: Dawid Weiss
> Assignee: Dawid Weiss
> Priority: Minor
>
> I am dissatisfied with how ANT and submodules currently work in Lucene/ Solr.
> It's not even the tool's fault; it seems Lucene builds just hit the borders
> of what it can do, especially in terms of submodule dependencies etc.
> I don't think Maven will help much too, given certain things I'd like to have
> in the build (for example collect all tests globally for a single execution
> phase at the end of the build, to support better load-balancing).
> I'd like to explore Gradle as an alternative. This task is a notepad for
> thoughts and experiments.
> An example of a complex (?) gradle build is javafx, for example.
