Steve Rowe commented on LUCENE-8106:
------------------------------------

[~thetaphi]: I've run into trouble getting the script ^^ to work.  First, the 
local log isn't where it is on my Jenkins 
({{workspace/../builds/$BUILD_NUMBER/log}}, so I switched to fetching the log 
via HTTPS and storing it in a temp file.  That seems to work.  But now there 
are problems dealing with {{lucene.build.properties}}:

> This script will be runnable from a downstream job triggered by an upstream 
> failing Jenkins job, passing log location info between the two.
> The script will also be runnable manually from a developer's cmdline.
> From the script help:
> {noformat}
> Usage:
>      python3 -u reproduceJenkinsFailures.py URL
> Must be run from a Lucene/Solr git workspace. Downloads the Jenkins
> log pointed to by the given URL, parses it for Git revision and failed
> Lucene/Solr tests, checks out the Git revision in the local workspace,
> groups the failed tests by module, then runs
> 'ant test -Dtest.dups=5 -Dtests.class="*.test1[|*.test2[...]]" ...'
> in each module of interest, failing at the end if any of the runs fails.
> To control the maximum number of concurrent JVMs used for each module's
> test run, set 'tests.jvms', e.g. in ~/lucene.build.properties
