[isabelle-dev] build and run Isabelle/jEdit on the spot

[Christian Sternagel]

Hi again,

after cloning the Isabelle repository from scratch the Isabelle/Scala 
layer finally builds. However, when building Isabelle/jEdit I still get 
the error

src/plugin.scala:410: error: value setStyleExtender is not a member of 
object org.gjt.sp.util.SyntaxUtilities
     SyntaxUtilities.setStyleExtender(new Token_Markup.Style_Extender)
                     ^
src/token_markup.scala:82: error: type StyleExtender is not a member of 
object org.gjt.sp.util.SyntaxUtilities
   class Style_Extender extends SyntaxUtilities.StyleExtender

My setup is:

$ ~/Repos/isabelle/bin/isabelle getenv JAVA_HOME
JAVA_HOME=/usr/java/jdk1.6.0_23

$ ~/Repos/isabelle/bin/isabelle getenv SCALA_HOME
SCALA_HOME=/usr/local/Isabelle2011/contrib/scala-2.8.1.final

$ ~/Repos/isabelle/bin/isabelle getenv CLASSPATH
CLASSPATH=

$ `~/Repos/isabelle/bin/isabelle getenv -b JAVA_HOME`/bin/java -version
java version "1.6.0_23"
Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
Java HotSpot(TM) 64-Bit Server VM (build 19.0-b09, mixed mode)

$ `~/Repos/isabelle/bin/isabelle getenv -b SCALA_HOME`/bin/scala -version
Scala code runner version 2.8.1.final -- Copyright 2002-2010, LAMP/EPFL

Maybe my CLASSPATH needs to be non-empty? Any ideas?

cheers

chris
