[rules-dev] build failure UrlResource & org.apache.commons.codec.binary

[Geoffrey De Smet]

Since commons-codec is an optional dependency of drools-core, it should 
be in the classpath of drools-core when it compiles,
so the build error should not occur.

Optional just means that anything that depends on drools-core doesn't 
get commons-codec on its classpath as a transitive dependency, except if 
the explicitly declare a dependency on it themselves.

Strange that no longer declaring it optional fixes it, must be a maven 
2.0.9 quirk. :/

Another strange this is that the version of commons-codec is declared in 
drools-core pom.xml, not in depedencyManagement of drools pom.xml.
I 'll fix that.


The drools hudson build uses Maven version: 2.0.10,
but hudson can work with multiple versions of maven.
I believe we should force a minimum version of maven 2.2.1 ASAP,
starting with switching the hudson drools project config (takes about 20 
secs if someone got the privileges).
By switching to maven 2.2.1, the transition to maven 3 will be a lot 
easier because 2.2.1 warns if we do nonsense (like declare the same 
dependency multiple times).

With kind regards,
Geoffrey De Smet
