Subject [jira] [Commented] (LUCENE-5755) Explore alternative build systems
Date Tue, 01 Jul 2014 18:50:24 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-5755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14049180#comment-14049180

Dawid Weiss commented on LUCENE-5755:
-------------------------------------

RandomizedRunner and Ant's launcher for randomized testing are two different things. The launcher
for Ant does more things than just isolate/ fork the subprocess JVM. See here for an overview.

http://labs.carrotsearch.com/download/randomizedtesting/2.1.2/docs/junit4-ant/Tasks/junit4.html

{code}
java.lang.RuntimeException: Suite class org.apache.lucene.util.TestVirtualMethod$TestClass1
should be public
{code}
You need to filter out nested classes from the pattern; these are not tests.

I'm not saying gradle's test runner cannot be used -- it probably can be -- but you'll lose
some of the functionality specifically written for Lucene (such as load balancing, cwd isolation
or master seed propagation).

> 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.
