Scala Plugin for Eclipse 2.7.4 RC + Maven Multimodule; Issues

http://code.google.com/p/esmi/wiki/CreatingScalaMavenProjectsInEclipse

I plan to keep the above up-to-date as much as I am able.  My steps are usually as follows (Note, I use q4e + m2e interchangeably now, depending on mood).

1) Import project as maven project using q4e or m2e
2) Fix Source directories if they did not import correctly
3) Right click on the project and Add scala nature

PLEASE make sure you are either A) using different output directories for maven builds/eclipse builds or B) use the *exact* same version of eclipse scala plugin as the version of scala declared in your pom.xml!!!


If you want to use the maven-eclipse plugin, feel free, however it only knows about source directories defined in the build-helpers-plugin (or the "root" source directory), so feel free to modify it.

Hi,

I have been using the RC for Eclipse Plugin 2.7.4 for mixed Java/Scala
development and everything works reasonably well (kudos to developers)
until I throw maven into the equation.

So, before getting into more detail, has anyone managed to get a
1)maven, 2)multimodule, 3)mixed java/scala eclipse project running (
both presentation and build )?

If so, what combination of POM  + Eclipse settings works?
( I am following the src/main/scala conventions )

I can be more specific on the issues ( which are many ) but perhaps
this is a common scenario.

Scala rocks ;)

Thanks!

Target dirs were indeed misplaced.
Now, regarding the version. I am using 2.7.4 RC1 for the eclipse
plugin, which is supposed to be better ( and looks like it is ).
However, I can't find the matching version of scala-library in the
scala-tools maven repo.
Of course I can put it up somewhere else, which leads me to the question:
Which distribution of the RC (jar artifact) should I install in the repo?
from this page:
http://www.scala-lang.org/node/211

The OSGi bundle?
http://www.scala-lang.org/downloads/distrib/files/scala.library_2.7.4.RC...

I am still fighting with Eclipse, but things look better ;)

Thanks,
A

np!

As soon as we have nexus up and running smoothly, we should be able to deploy the 2.7.4-rc1 to the maven-snapshots repository (which you can use if desired).

Sorry for the delay!

Hello,

Just FYI. Apparently checking out "modules as different projects" with
m2e is the way to go (as opposed to nested projects/folders).
That, and following your advice, solved my classpath/output/etc problems.

I prefer separated projects anyway ;)

Thanks!
