Karl Heinz Marbaise commented on MNG-6265:
------------------------------------------
Tests are running on each module and not on a reactor base or do you mean the
tests in different modules? Furthermore what do you mean by {{mvn install
-DskipTests; mvn test}} ? Is the reactor order different from the {{mvn
install..}} than from {{mvn test}} after ? The order of running tests within
the modules can be controlled by use the option {{-Dsurefire.runOrder...}} as
you mentioned...
Do you have defined correct dependencies between your modules in your reactor ?
It sounds like you didn't? Cause the reactor order is defined by the
dependencies...?Can you give a concrete example ? What is the real problem you
are trying to solve?
> Controlling reactor order of modules
> ------------------------------------
>
> Key: MNG-6265
> URL: https://issues.apache.org/jira/browse/MNG-6265
> Project: Maven
> Issue Type: New Feature
> Components: core
> Affects Versions: 3.5.0
> Reporter: August Shi
> Attachments: p.patch
>
>
> We have a use case for controlling the reactor order in Maven, specifically
> for running tests on Travis. The common pattern is to run "mvn install
> -DskipTests; mvn test". After modules are installed (in the default order),
> the modules can be run in any order during testing, e.g., running the failed
> modules first, as in -Dsurefire.runOrder=failedfirst for Surefire.
> Would this feature be useful for others? I am attaching a *draft* patch that
> implements this feature by modifying DefaultMaven.java. I see no clean way of
> implementing this feature through an extension, unless some new callback,
> e.g., afterProjectsOrdered, is implemented first. Would it be worthwhile to
> improve this draft?
> One can test the feature by applying the patch, building Maven, and running
> tests with the modules in a random order like this:
> $ mvn -DdistributionTargetDir=$(pwd)/apache-maven-3.5.x-SNAPSHOT clean
> install -DskipTests
> $ apache-maven-3.5.x-SNAPSHOT/bin/mvn test -Dmaven.project.order.file=<(ls -d
> maven* | shuf)
