Ecj problem, bulding classpath

If you run into problems that your environment has an ecj that does not pass the checks in configure. You might want to try this: To ensure that your Gentoo has the right version of the eclipse compiler First you may have to unmerge the current eclipse-ecj

# emerge --unmerge eclipse-ecj
# cd /etc/portage
# echo ">=dev-java/eclipse-ecj-3.4" >> package.mask
# emerge eclipse-ecj --pretend
# emerge eclipse-ecj

Then,

# bitbake classpath -c clean 
# bitbake classpath

Building Classpath

Building Classpath resulted in an error that was caused by a faulty classpath to the antlr.jar. The error may be a symptom of something else but --with_antlr_jar= addition to classpath_0.98.bb recipe got me past the issue:

EXTRA_OECONF += "\
               --disable-alsa \
               --disable-dssi \
               --disable-qt4-peer \
               --disable-plugin \
               --enable-gconf-peer \
               --enable-gtk-peer \
               --enable-local-sockets \
               --with-vm=java \
             --with_antlr_jar=~/overo-stable/tmp/staging/i686-linux/usr/share/java/antlr.jar \
              "

Java on the stick

I still seem to miss some setting or packages to make it work.
