Hi everyone,
> My use case is that I want to run a class from a Maven artifact.
I turned my "synthesize a dummy POM" approach into a full-blown shell
script called jrun [1].
You can use it to conveniently run Java code from any remote Maven
repository. For example, to spin up the Jython REPL:
$ jrun org.python:jython-standalone
If you add the ImageJ Maven repository to your ~/.jrunrc:
[repositories]
imagej.public = https://maven.imagej.net/content/groups/public
Then you can launch ImageJ (https://imagej.net/):
$ jrun net.imagej:imagej
Or even the entire Fiji distribution of ImageJ (https://fiji.sc/), which as
of this writing consists of 346 components!
$ jrun sc.fiji:fiji:LATEST
All without explicitly downloading or installing anything apart from Maven
and this one shell script [2].
If anyone knows a better / standard / best-practices way of doing this,
please let me know! But I am pretty pumped about how convenient this is. I
hope that jrun is useful to other developers too.
Regards,
Curtis
P.S. If the Mojohaus devs are interested, perhaps we could fold in
something like this as a new goal of the exec-maven-plugin.

[2] Windows users need POSIX-compliant shell, though. I did not test it yet.
