Severe loss of functionality after install of nightly Scala Eclipse Plugin (2.8.0.r20494-b20100114032916)

Last night I updated an apparently healthy Eclipse (3.5.1 jre1.6_17 WinVista) to use the nightly Scala plugin, from a previously working nightly version dated mid December.

Immediately afterwards, all Scala and Java functionality in Eclipse seemed to be rendered inoperable; eg no source folders in project view, no Java or Scala related items in any context menu, no ability to open Scala or Java editors. It was really strange, never seen anything like it.

There was some clues in the log of what happened - Ive extracted possibly relevant sections of the failing session below .

Uninstalling the Scala plugin restored regular JDT java functionality. But I could not rollback to prior install ("missing from repository"), so I'll probably have to do manual install of a good build (suggestions?).

Anyone else getting this...?

I've not had any similar reports, and I'd be surprised if this was
specific to the Scala tooling rather than a generic issue with Eclipse
updates.

Try installing the most recently nightly and let me know how you get on.

Normal functionality has been restored with the next nightly install :) Although looking at the commit log, I dont think the improvement is anything to do with changes in the code...

Maybe as you say, the last update installation was corrupted in some way, and combined with the AOP, that managed to disable both the SDT and JDT...?

Since uninstalling just the SDT did restore the JDT, it was definitely something related to the Scala plugin.

That kind of side-effecting fragility is perhaps a consequence of the AOP weaving?

Yes, that's possible. But really I think you were just seeing a borked
update here ... it happens, it's messy.

Re: Severe loss of functionality after install of nightly Scal

Hello Ben,

This happens to me about one in two or three updates. Usually the list of
perspectives Eclipse knows of has been corrupted listing the Scala plugin as
and the Java plugin as but sometimes they are completely gone
along wiith the Debug perspective.

At first I used to do a re-install of Eclipse and then install the plugin
which always worked. Later I discovered that starting Eclipse from the cmd
prompt with the -clean option solves the problem as well. Some state like
the content of the Ant view will be cleared and some views will be restored
to their default state but that is only a minor inconvenience.

I gladly go through this routine to enjoy the constant improvements in the
plugin (thanks for that Miles!)

Gr. Silvio

Re: Severe loss of functionality after install of nightly Scal

I've had a some weird eclipse behavior like that. But every time it
was solved by a eclipse -clean . The only time -clean haven't solved
problem, I noticed that the JDT weaving was off, turning it on solved.

That's good advice: I always launch Eclipse with the -clean option.

Cheers,
