Reopening to add some more functionality to the script:
# Add cmdline option parsing
# Run {{git fetch}} by default prior to running tests, and allow opt-out (for
Jenkins) via cmdline option {{--no-fetch}}
# Add cmdline option for test iterations, defaulting to 5
# Sort failure report by reverse failure count, so that highest counts are on
the bottom, with secondary sort on test suite name
# When all iterations fail for a test, re-test at branch tip (with the seed)
# When a test also fails 100% at branch tip, re-attempt without the seed

> URL: https://issues.apache.org/jira/browse/LUCENE-8106
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Steve Rowe
> Assignee: Steve Rowe
> Priority: Major

> 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
> {noformat}
