Re: Eclipse plugin: NoSuchMethodError: scala.tools.nsc.ast.parser.MarkupParsers$class.$init$(Lscala/tools/nsc/ast/parser/MarkupParsers;)V

I would suggest trying the 2.7.4 final version rather than the nightly and see if that fixes the problem. the 2.8.0 compiler / library etc. seems to be in flux right now.

the update site is:

Hi,

I just updated the Eclipse installation on my netbook, including the
Scala plugin from about 2 weeks ago to the latest nightly build, and now
I'm getting a NoSuchMethodError (as shown below) when I try to open a
Scala file.

I tried reverting to the previous Eclipse configuration, uninstalling
and reinstalling the Scala plugin and using a new workspace but I still
get the same errors. Does anyone have an idea what might be wrong before
I try to reinstall Eclipse from scratch?
