Running from ide as equinox enabled application

[Artem Nikiforov]

Hi!

I'm on commit 1dfe6b9c9f348f683e07c649f7e9ebedffd86bda

I'm running a build with ./build-all.sh -P scala-2.11.x -P eclipse-kepler clean install -DskipTests

and project builds successfully. Then I can install artifact with "help -> install -> archive" in eclipse and I get working scala-ide.

Right click on sdt.core -> Run as Equinox weaving enabled application. I get this error in the box, when eclipse starts:

"

Errors occurred during the build.

Error instantiating builder 'org.scala-ide.sdt.core.scalabuilder'.

Plug-in org.scala-ide.sdt.core was unable to load class org.scalaide.core.internal.builder.ScalaBuilder.

Plug-in org.scala-ide.sdt.core was unable to load class org.scalaide.ui.internal.editor.ScalaSourceFileEditor, with detail button. If I click on detail button I see this stacktrace:

org.eclipse.core.runtime.CoreException: Plug-in org.scala-ide.sdt.core was unable to load class org.scalaide.ui.internal.editor.ScalaSourceFileEditor.

Open your run configuration and navigate to Plugins tab. What do you have selected in "Launch with"? If it is "x selected below only" and you click on "Validate Plugin-ins" do you get warnings about the org.scala-ide.* plugins? If yes, click on "Add Required Plugins" - that should fix the problem.

Thanks for response!

In "Launch with" there was "all workspace and enabled target plug-ins". I've clicked on Validate plug-ins, and got "no problems were detected" dialog.

I've chosen plug-ins selected below only, clicked Validate, "no problem were detected" dialog appeared.

I've checked the checkbox Validate plug-ins automatically prior to launching, launched through "Equinox enabled...", same errors occured.

Ok, then I have no further clue what the problem could be (by not seeing your current workspace configuration). Do you have the scala-ide.aspect project imported (that was a problem for someone else)?

The problem got solved.

I've installed scala-ide on luna. According to my multiple installation it seems, that:

1) A person can't develop scala-ide in kepler now. The mentioned errors arrize.

2) When developing from luna a person shouldn't install ajdt from ajdt site, otherwise you get into loop

( 1 run -> 

  2 dialog shows, that "jdt weaving is currently disabled" and you should enable it for scala to work properly

  3a if you click enable, then go to step 2

  3b if you click continue as is, then source code editor crashes. )

Artem, I'm very sorry for the broken instructions. There's been a pull request on docs that we forgot to merge. I just did, and the page looks a bit different now: http://scala-ide.org/docs/dev/setup/setup.html

There is no Luna release version of AJDT, I think, so I used the milestone site from here: http://download.eclipse.org/tools/ajdt/44/dev/update
