scala plugin does not install

In IntelliJ IDEA 12 community edition, when I try to
Configure->Plugins->scala

I get the following error:

Plugin org.intellij.scala failed to initialize and will be disabled:
scala/runtime/VolatileObjectRef
Please restart IntelliJ IDEA



any idea or workaround?

Which version of IDEA 12? Which OS?

I'm trying to use:
IDEA 12 community edition, Leda-IC-123.4 on Mac OSX 10.8.2
I've tried deleting and re-installing, but that did not work.

I've just started using intelliJ a few days ago, specifically to use scala.
I installed IDEA 11.1 and the scala plugin works well in this version.

Can you send me log file from directory ~/Library/Logs/IntelliJIDEA12 ?

thanks for taking the time to look into this.

I looked around but there is no log file, I suspect it is because it has not really crashed.

I have downloaded the latest IDEA 12 CE 124.45, and with both systems I have the following problems:

case 1:
from the start panel go into the plugins and see that scala is not ticked. I tick the box and
press ok or apply, a dialog pops up to restart. At the restart I get the error I reported before.
Now the scala plugin is ticked on, but it is not present, no facet etc...

case 2:
at the start I choose to open a scala project. All loads ok, but there is no scala.
The event log tells me: Error Loading Project: Cannot load facet Scala ...
I go to the preferences -> plugins and tick the scala plugin on. Press ok, does a restart, gives me
the same dialog as before, but now gives me a blank (grey) screen and cannot open any projects.



really anoying.

It looks quite weird, I just made clean install of IDEA 12 CE (123.45), and plugin installation works like expected.
Try to remove plugin completely from disk (you can find plugins directory according to this instruction: http://devnet.jetbrains.net/docs/DOC-181), then install it again.

Alex,

I've removed the plugin as per the instructions. All is working well now (except it is quite slow). Thanks for your efforts.
I'm off exploring intellij

What kind of slowness are you experiencing?
