--------------------------------
Summary: Allow adding multiple launchers to a jlink'ed image
Key: MJLINK-83
URL: https://issues.apache.org/jira/browse/MJLINK-83
Project: Maven JLink Plugin
Issue Type: Improvement
Affects Versions: 3.2.0
Environment: (applies to all platforms)
Reporter: Peter Hull
The {{jlink}} command line tool allows the {{--launcher}} argument to be
specified multiple times to create multiple launcher scripts in the image.
However the maven plugin only passes on one {{<launcher>}} element from its
configuration section to the tool. If multiple are specified, the last one
takes precedence. I would like to improve this so the plugin will pass multiple
launcher specs on to the {{jlink}} tool. I suggest the config should look like:
{noformat}
<launcher>command=module/main</launcher>{noformat}
(as before, for backward compatibility and the common case where there is only
one)
or
{noformat}
<launchers>
<launcher>command1=module1/main1</launcher>
<launcher>command2=module2/main2</launcher>
...
</launchers>
{noformat}
where {{<launchers>}} can contain zero or more {{<launcher>}} elements with the
same syntax as the existing element.
One remaining question - what do do if the config specifies both
{{<launcher>}} and {{<launchers>}} - combine the two or signal an error?
