Using the jsr223 engine in maven

hacking
1

I took notice that the Lucee 5 build process itself uses the JSR 223 scripting engine to generate lar files.

I am interested in using the same thing to package my cfm resources into .lar files for final distribution. So far I’ve been having problems getting it to actually run.

Here’s what I have so far:

pom.xml

build output:

Any idea what may be causing this?

you can download a much more simple example here:
http://dev.lucee.org/download/ant.zip

this zip does not include the OSGi bundles needed by lucee, so Lucee will start to download them on the first startup, unless you copy them to this location /assets/lucee/lucee-server/bundles, you can download them here (http://preview.lucee.org/download/ → “Dependencies”)

@micstriit, thanks for the advice - I just found this worked before I read your comment:

@dajester2013 I think a blog post or something about what you get working would be pretty cool. There’s a lot of possibilities here.

maybe it should also include how to install Lucee in ant (classpath), so must of the addional steps are not necessary at all.

6

@bdw429s I guess I ought to start a blog then… lol. I’ll share when it’s up. By way of preview, I’ve successfully set up a project to build Lucee5 component archive libraries (the final artifact is a .lar file to be deployed as a component mapping).

7

(I accidentally posted this on the wrong thread, moved it here…)

So I started writing some posts on a brand new blog, and realized just how terrible I am at writing blog posts. So I put a repo on github with some (very) basic example projects to show how I’m approaching working with Maven for Lucee projects:

I plan on working on some more examples and adding them. Also, I am pretty much still a newcomer to Maven, so if anyone sees an area that I implemented poorly, please let me know.
