Hi all,
I am rather new to large scale Scala projects in general. I would like to explore the scala-ide sources (hoping to contribute somewhere ahead), but I am having troubles getting the initial workspace setup. Cloning the git repo is unproblematic, but when I import the projects into the workspace, I get close to 2000 broken dependencies. Most of them seem related to jars that should be in the org.scala-ide.sbt.full.library/lib directory. However, this directory is not present.
What am I missing? I know I could symlink to some of these deps locally, but is there no way to pull all dependencies directly somehow? After all the project is clearly expecting them to be present.
Sorry if I missed something obvious, still getting my bearings.

Did you follow the instructions on the ScalaIDE website? Worked quite
fine for me:

hope that helps,

org.scala-ide.sbt.full.library/lib directory will be populated with
the following step:
$ ./build-toolchain-2.9.x.sh

Thanks for the help, both of you! Running the build script as indicated in the guide fails with the following output...I have tried both Java 6 and 7 with the same result. All prereqs should be accounted for (both Maven 2 and 3 installed).

Interesting, I have no idea.. you definitely need to use Maven 3 and
Java 6, that's the combination that works. Maybe deleting your
.m2/repository could help?

No luck :-/
It seems this exception is linked to JRE incompatibility, however, since I am on OpenJDK 1.6 that should not be an issue.

Looking at the stack, it just might be an issue of JDK1.7 anyway (see the Maven calls). Further, I tried purging JDK1.7 from the system only to find a huge stack of packages depending on it, including most Maven packages, so I am guessing it runs a little deeper.

Exception says that you are trying to load a class javax.inject.Provider compiled for JDK 7 (class version 51.0) into a lower level VM.
Have you tried installing Sun JDK 7 from a binary tarball, bypassing Linux package mechanism and using it instead?
cheers,
