What is the current status of Eclipse Luna compatibility?

[Eugene F.]

Is there a stable version of Scala IDE Plugin for Eclipse Luna?

I heard that there are problems with  Scala IDE 4.0.0 Milestone 3.

What is the current status?

[Andrew Gaydenko]

I'm using m3 under Luna every day (Linux). Which compatibility issues do you mean?

[Eric Peters]

I'm using Luna w/Milestone 3 on OSX and it seems to work great.

[Som Snytt]

I just installed on the "JEE" configuration and the Scala plugin breaks.

The log says:  "Unable to resolve resource org.scala-ide.sdt.core" etc etc, Chain 1, Chain 2.  Nothing that is meaningful to me.

Edit: actually the long error message scrolls off to the right about a mile: "because it is exposed to package 'javax.xml.bind' ... via two dependency chains."  Hence the two chains, I guess.

The unfortunate part is that I switched from working with Kepler and v3, so I just tried my Luna and couldn't remember if I'd already installed Scala.  My first assumption was that it thought incorrectly that I'd already installed Scala.

There is no red icon or indicator that says "Scala is installed but broken".  There is no icon at all on the "About Eclipse" box.

Sorry for the noise if there's already something on the web site or twitter telling me not to install on JEE Luna.

I heard nothing problematic about JEE Eclipse+Scala IDE therefore I
can't help you here, but you should post the full error message maybe
someone else can.

[Joakim Olsson]

I had exactly that problem yesterday. I uninstalled everything that was related to Scala and re-installed it and it seems to work as it should now.

FWIW I seem to remember having trouble with the JEE bundle on earlier versions of Eclipse, possible Luna too (though if I tried it that would have been pre-release).

Ivan,

Could you please try out the nightly Luna build from here? It should be fixed, and it would be great to get confirmation it really is:

http://download.scala-ide.org/nightly-scala-ide-luna-211x

Others have reported on this mailing list that running `eclipse -clean` solved this problem for them.

I can report that the nightly worked for me, but the milestone had not.

It came up on SO, where nightly was suggested.

The luna branch isn't updating during three weeks https://github.com/scala-ide/scala-ide/commits/platform/luna So I was sure it is in the last milestone state. Have I missed something on luna? :)

[Som Snytt]

Don't laugh, but I thought I'd download the two zips and compare, but they are very different sizes, so I won't bother digging around.

Meld for one makes comparing directories pretty manageable...

Mind-meld for one, the Spock utility?

It was a factor of 3 difference; I didn't think about compression ratios, but just assumed the packaged product was very different.

OK. I can reproduce the problem now. It is only visible with the 'JEE' favor of Eclipse. The conflicting bundle is not is the 'standard' distribution.

I'll try to rework the dependency declaration to avoid this conflict.

Cheers,
