# Invoke Yetus locally to validate a patch against Lucene/Solr, and 
# (optionally) post a validation report comment on the passed-in JIRA issue
# from which the patch was downloaded.
#
# NB 1: The Lucene/Solr Yetus personality currently performs the equivalent
# of "ant precommit" and "ant test" in modified modules; instead of using
# this script to test your changes, please consider invoking those targets
# directly.
#
# NB 2: The Jenkins job "PreCommit-Admin" automatically detects new patches
# posted to LUCENE and SOLR JIRA issues that are in the "Patch Available"
# state, and then queues the appropriate "PreCommit-LUCENE-Build" or 
# "PreCommit-SOLR-Build" job pointing to the JIRA hosting the new patch.
# Those jobs perform the same checks as this script, and like this script,
# will post a comment on the JIRA issue.  As a result, manual invocation
# (e.g. via this script) should ordinarily not be necessary.
# 
# Environment variable ${YETUS_HOME} must point to the separately installed
# Yetus home directory, e.g. the "rel/0.7.0" tag checked out from a local
# Yetus Git repository. 
#
# Environment variable ${PROJECT_DIR} must point to a local Lucene/Solr git
# workspace dir.
#
# The sole cmdline param can be a JIRA issue, a local patch file, 
# or a URL to a patch file.
#
# If the cmdline param is a JIRA issue, the patch to download and validate
# will be the most recently uploaded patch on the issue.  See the patch
# naming schema that Yetus recognizes: 
# https://yetus.apache.org/documentation/in-progress/precommit-patchnames/ 
#
# If the cmdline param is a JIRA issue and you provide JIRA user/password via
# environment variables ${JIRA_USER} and ${JIRA_PASSWORD}, a patch validation
# report will be posted as a comment on the JIRA issue.
