Can "mvn jetty-run" skip compile?

[jamesqiugm]

I use eclipse + mvn jetty-run to develop lift, .scala files are
compiled with eclipse scala plugin, but every time start "mvn jetty-
run", mvn will try to compile all the .scala source file again(and
it's really slow). My question is: can I skip mvn's compile? thanks

I don't know if it's possible, as jetty:run  "Requires dependency resolution of artifacts in scope: runtime"

=> compilation done.

3 possibles work-around :

* Have you try to "Run As >. Scala Application" src/test/scala/RunWebApp under eclipse ?

* maven-scala-plugin use a timestamp file to memorize date of last compilation and compare the lastModification date of this file to source file.

  try "touch target/classes.timestamp && touch target/test-classes.timestamp && mvn jetty:run"

* configure maven-scala-plugin to use the same ".scala_dependencies" as eclipse

  (see http://github.com/davidB/maven-scala-plugin/wiki/Tips )

Tell us which work-around you choose.

Have you tried using jrebel to avoid having to restart jetty? It has
been a while since I played with lift and jrebel but it used to just
work iirc.

FYI, It still does work well :-)

Cheers, Tim

but doesn't avoid to restart if change some init code (Boot, DB conf,....)

Use it with RunWebApp - there is a free personnal license for *.scala files.

Yes, I use JRebel for snippet hot deploy without restart jetty. But
sometime still need to reboot it (change Boot.scala, etc.). the .scala
files have been compiled by eclipse, they're updated, but mvn don't
know and try to recompile them one more time.

Thanks david. I've try the first 2 ways, both work fine.
* Now I found "Debug As > Scala Application" RunWebapp.scala in
Eclipse is the most comfortable way for me.
* If I use "mvn jetty-run", your "touch target/classes.timestamp"
method is a real perfect solution for my original problem.
Thanks again.
