GWT 2.8 SnapShot "Unexpected internal compiler error" in SDM after switching to GSS

[confile]

I use GWT 2.8 SnapShot with an app that runs with CSS only no GSS. Then I switched to GSS using: 

<set-configuration-property name="CssResource.enableGss" value="true" />

<set-configuration-property name="CssResource.legacy" value="true" />

<set-configuration-property name="CssResource.conversionMode" value="lenient" />

When I compile with option -strict there are no errors. When I run my server in SDM and try to connect I get the following errors: 

         Compiling 1 permutation

            Compiling permutation 0...

            [ERROR] Unexpected internal compiler error

It compiles perfectly with GWT 2.7 and GSS. So the problem must be in the GWT 2.8SnapShot.

I don't know if it will solve your problem but the configurationProperty CssResource.legacy is not needed anymore:

So remove: <set-configuration-property name="CssResource.legacy" value="true" />

I tried this but it did not solve the problem.

If you can provide a small sample that reproduces the problem I will take a look.

I hit a similar problem.  I Turned on GSS with GWT 2.7 Release.  I converted one of my files to .gss and let the converter handle the other files for now.  Everything compiles fine.   Super Dev Mode will start and the first compile will work fine.  If I make a change the next incremental compile fails with the UnableToTomplete exception, with it outputting code that applied styles in the gss.  I turned gss off and reverted that file back to css and the incremental compile started working again.

Can you provide a small repro case and open an issue for it?

Hey Guys,

sorry for being off-topic but where can i find current 2.8.0 snapshot jars?

i found this repository https://oss.sonatype.org/content/repositories/google-snapshots/com/google/gwt/gwt-user/2.8.0-SNAPSHOT/ but it does not contain any jars.

thanks! :)

The repository is correct but http://build.gwtproject.org/job/gwt/ hasn't produced a successful build the last days and I think old jars are removed automatically by sonatype.
