Sconscript: manage java binding if first build

Clement Champetier · Clement Champetier · commit d9e17b91475c · 2014-08-18T15:21:23.000+02:00
* We can't generate JAR file while first build, because java classes are
not already generated. Need to relaunch the build to generate it.
* Print a warning message for java binding if first build.
* Generate JAR file when it's possible.
