Using latest Maia EAP build and latest Scala plugin EAP build, setting up a project with existing sources results in no .scala files showing in the Project window. Directory structure is there but no scala files. No Scala classes show in the Packages view either.

Should be fixed in last Nightly Build.

any idea when a version of the scala plugin will work with 10762 of Maia?
Sep 16, 2009
Andreas Joseph Krogh
Latest, 27038, seems to introduce the same problem mentioned by "Anonymous" Aug 18, namely that no Scala-classes show up in the package-explorer and it doesn't seem to know about any Scala-classes in the project resulting in lots of "red code" in your Scala-files.
Sep 16, 2009
Stefan Endrullis
I'm using the same version and I can see Scala classes in the package explorer. Are you sure you have activated the Scala plugin after the upgrade?
But I have another problem with the 27038. I cannot build my project anymore. It hangs during the build process just saying "Make". It does not finish the make process and you cannot cancel it. One has to xkill IDEA in order to get rid of this impasse. I also tried to "rebuild the whole project", but it's the same. Any suggestions?

27069 works OK, but pressing CRTL+F1 then "1. Project view" doesn't work for Scala-classes. I have to CTRL-click on the package in the Scala-file to navigate to it in the project-view.

Stefan Endrullis
Same problem with build 27069.

What scala-libs and compiler are using? I'm using the ones at http://scala-tools.org/repo-snapshots not the ones supplied by the plugin. Oh, btw, I'm using 2.8.0-SNAPSHOT, that's my whole motivation for trying out MAIA as 8.1.x it severely broken with scala-2.8.0-SNAPSHOT.

I'm using a 2.8 version that I have build from trunk some days ago, and it worked very well with the Scala Plugin #26899 (IDEA #10666). OK, I could try to compile the very latest Scala now..., but first I will test Scala Plugin #27103.
Sep 18, 2009
Stefan Endrullis
OK, now I tried the Scala Plugin #27103, but it's still the same. IDEA hangs, when it tries to build the project. Therefore upgraded the Scala libs (because the compilation of Scala takes very long, this time I used the pre-compiled libs from https://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/lib that have been updated yesterday). But the behavior remains the same. The problem is that I don't get any error.

Right now I wanted to create an bug report, but the new bug tracker doesn't allow it anymore. Thus I have to post the bug here in the hope that a developer is reading it and creates a bug report. If so, please post the link here.
Summary: IDEA does not finish building the project
I'm running IDEA Maia 10762 with Scala Plugin (tried build 27038, 27069, and 27103) and I cannot compile my projects anymore. If I press the compile button or select "Rebuild project" in the menu, IDEA seems to start the compilation (Hint in status bar switches to "Make"), but it does actually nothing (consumes only 0% CPU) and it never finishes the compilation. You cannot even cancel the compilation.
To reproduce you do not even need to have files in you project nor have the Scala facet activated in the project. But you have to enable the Scala plugin. Without Scala plugin it's not hanging during the compilation!

Please use forum for describing problems (If tracker is not working, but tracker must work now).
I didn't see problems with compilation. So I need more information for it. What Scala compiler version you used or you use compiler which is built-in plugin.
Sep 23, 2009

OK, in future I will report problems in the forum. BTW, I filed the corresponding bug report here: http://jetbrains.net/tracker/issue/SCL-1530

Suggestion to improve this page: It would be good if one could add comments to certain builds, since the rating alone does not clarify what problems occurred.

I'm curious about whether the newest nightly build, such as 0.3.2x can be used on the IDEA Community Edition and how? I tried to directly copy or overwrite the original scala plugin. But in most cases it does not work at all or does not work properly with a lot of error log showing up.

0.3.32 works fine with the community edition.

0.3.55 does NOT work with the community edition, or at least not with MAIA-IC-90-96 and I could not find a newer version
Oct 23, 2009
Stefan Endrullis
I tried it with the ultimate edition MAIA-IU-90-94 that should be compatible to the plugin as mentioned in the list, but it doesn't work, too. I've started a thread to discuss the problem.

Does build 98 work with maia-90.137?

Yes, seems so, but I've tested it only some minutes so far.

It would be nice to able to rate the plugin against 2.7 vs 2.8 code, as I tend to see stability depending on scala version.

Can anyone suggest a combination of versions of IntelliJ (community edition) and Scala plug-in that work? I'm running IntelliJ "Maia-IC-90.193" on a mac and I can't seem to find a matching plug-in version. Thanks for your help! Nils
Dec 02, 2009
Stefan Endrullis
Most of the combinations mentioned in the list above work. The votings give you a good indication of what is worth to try. I'm currently running IDEA IU-92.65 with the Scala plugin #254, but I tried about 20 different releases now (I'm updating nearly daily using a script) and most of them (80-90%) worked.

Last build 335 lost the left bar tooltip which indicate when a scala method is overriden/implemented from a super class or trait.
It used to work in a previous version but forgot which one. Too bad, this feature is so useful for me as I'm extending many java claases/interfaces in scala and navigation was handy.
Hope it will come back soon. Anyway great job, kudos to the scala plugin team

I am feeling some pain when working with Scala code that uses not-fully-qualified imports, such as:
http://github.com/dpp/liftweb/blob/master/lift-base/lift-util/src/main/scala/net/liftweb/util/TimeHelpers.scala
Notice the "import common." which is imported from file in net.liftweb.util, which means it should resolve to net.liftweb.common.
IDEA does not seem to understand this, so imports from common are unresolved.
Any hints?
Jan 11, 2010
Alexander Podkhalyuzin
Imports works as for Scala 2.8. In Scala 2.8 relative imports are not supported.

The question is: where can we download 9.0.2 EAP builds? The Maia EAP page only points to the normal 9.0.1 release.
Jan 26, 2010

I reconed there were no 9.0.2 EAP around as this page links to the 9.0.1 relase, as you point out.
JetBrains: Any word on this?

Thanks for a great plugin, however it seems like there are some serious problems with performance. I typically have to wait ½ to 1 sec for code completion help in my different scala files. No file are more than approx. 120 lines. Are there any way I can improve this, or is it a high prioritity for the development?

Works for me without specifying any hostname or port. The fsc server seens to be started automatically.

What's up with the plugin (858 and 863 at least)? All my @BeanProperty annotations are marked as red. The "fix" is to import with "scala.reflect.BeanProperty" instead of just "reflect.BeanProperty". All my project's classes are imported with "root." as prefix, what's up with that? BTW: I'm using 2.8.0-beta1.

Mar 26, 2010
Andreas Joseph Krogh
With latest build, 976, the Exception is gone, but we're back the same import-crazyness as in 858. IDEA generates _root_.-imports for all and doesn't recognize reflect.BeanProperty as a correct import while the scala-compiler certainly thinks it OK. Is 976 ment to work with a later version of Scala-2.8 than beta-1, do I need latest SNAPSHOT?

The latest 1004 build is incompatible with the 95.4 RC IntelliJ build.

Sometimes when i compile using intellij+scala plugin, i get a "Compiler internal error. Process terminated with exit code 1" message.
What does this mean? where can i get a more descriptive error message?

This is most likely caused by OutOfMemoryError in compiler.

I used to tear my hair about about an issue that seems related, until I discovered the solution:
Always make sure the Scala facets in your project use the same compiler and library jars as other build tools (e.g. Maven/SBT/Ant) are using. It's not the default, so I always go through every facet, and explicitly set the compiler jar to ~/.m2/repository/org/scala-lang/scala-compiler/2.8.0-SNAPSHOT/scala-compiler-2.8.0-SNAPSHOT.jar and the library jar to the equivalent but s/compiler/library/g. Note that it's not relevant that I'm using 2.8.0-SNAPSHOT as such, you just need to make sure that the identical compiler and library jars are in use everywhere.
At the moment, Scala categorically does not have binary compatibility between versions, and it's an open question whether it ever will except in the occasional fortuitous circumstances.
This really should be a feature of the Scala plugin--first, an option to set compiler and library versions explicitly for the whole project, and secondly an option to synchronize them with Maven etc.
May 07, 2010

Multiple scala versions are usually causing much more horrible stacktrace from compiler.
I agree that ability to check for multiple versions is a must have feature.
The plugin could also get this from maven or dependencies list.

There were no instructions of how to install, so I just unzipped it in C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 95.54\plugins

Some of my fully-qualified imports are marked as unused despite being quite obviously used. It looks like use of static members of Java classes don't make the import inspector think that the import is being used. E.g.:
import java.util.concurrent.Executors
...
private val workerThreadPool = Executors.newFixedThreadPool(numWorkers)

With the latest build, you'll get an error saying that the Scala Facet could not be loaded. You should just remove this – they are no longer needed. Make sure you have scala-library.jar and and scala-compiler.jar as a dependency of each module with Scala code, the rest will happen automatically.

Looks like this is still a work in progress. For now it doesn't recognize the JAR file names of scala-compiler and scala-library if the are in the Maven style.

I have a multimodule Maven project using Scala. Recently I cannot compile from within IDEA any more. IDEAshows "Please, adjust compiler library in Scala facet: multiple scala-compiler*.jar's attached.". Re-importing the project or re-import all Maven-modules doesn't help.
Aug 10, 2010
Stefan Endrullis
I had the same problem. I fixed it manually by creating a new "library" in IDEA containing scala-library.jar and scala-compiler.jar. The only problem was that I could not select the jars located in my the local repository, because it starts with a dot and is therefore hidden in IDEA. So I had to create the library using a text editor. In case that you also use Scala 2.8.0 you can do that by creating a file called Maven__org_scala_lang_scala_2_8_0.xml in .idea/libraries/ of your project directory with the following content:
Afterwards you have to select "Maven: org.scala-lang:scala:2.8.0" as compiler in your scala facets.
