Bug#733234: Groovy fails with groovy.lang.MissingMethodException

Fri Dec 27 15:28:39 UTC 2013

Package: groovy
Version: 1.8.6-1
Severity: normal

Hi,

Using groovy to generate code in XBMC build fails.

Steps to reproduce:
apt-get -t experimental groovy
apt-get build-dep xbmc
dget http://http.debian.net/debian/pool/main/x/xbmc/xbmc_12.3+dfsg1-1.dsc
# if extraction fails
dpkg-source -x xbmc_12.3+dfsg1-1.dsc
cd xbmc-12.3+dfsg1/
sed -i 's/groovyc/# groovyc/' codegenerator.mk
make -f codegenerator.mk

Result:
...
groovy -cp "/usr/share/java/groovy-all-1.8.6.jar:/usr/share/java/commons-lang-2.6.jar:./tools/codegenerator:xbmc/interfaces/python"
\
        ./tools/codegenerator/Generator.groovy

groovy 1.8.6-1 from unstable fails differently:
...
groovy -cp "/usr/share/java/groovy-all-1.8.6.jar:/usr/share/java/commons-lang-2.6.jar:./tools/codegenerator:xbmc/interfaces/python"

 @ line 26, column 1.
   import Helper
   ^

1 error

make: *** [xbmc/interfaces/python/generated/AddonModuleXbmc.cpp] Error 1

But it gives less clue about the actual problem.
Trying different JREs gives more hint:

I started working on a fix handling the exceptions somewhere, but now
I think caching signatures from java.lang and other system packages is
simply not portable.

Cheers,
Balint
