I have a similar tool that can be used to provision from and to a repository.

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.

Download an artifact and its dependencies without a pom.xml

2017-03-02 Thread Curtis Rueden 
Hi everyone,

Is there an easy way to download an artifact and its dependencies to a
folder locally?

* dependency:get will download a single artifact without needing a pom.xml.
* dependency:copy-dependencies will copy the dependencies of the current
project to a target location.

But can these two functionalities be combined?

My use case is that I want to run a class from a Maven artifact.

The best I have come up with so far is to synthesize a dummy POM:

g=org.scijava; a=scijava-common; v=RELEASE;
m=org.scijava.script.ScriptREPL; echo
"4.0.0xx0$g$a$v"
> pom.xml; mvn -DoutputDirectory=. dependency:copy-dependencies; rm
pom.xml; java -cp '*' "$m"

Can this be done more elegantly?

Thanks,
Curtis
