[rules-users] Drools 4.0.5 with Maven and JDK 1.4

[Mark Proctor]

Sounds like when the MVEL author release 1.2.24 he didn't do a valid 
pom.xml - I'll let him know.

There is also another problem with the 4.0.5 and the MVEL eclipse 
configuration - see email thread below. I'm going to push for a 4.0.6 
release next week, to address this.
1.2.25 or 1.2.24 is fine - as long as you always use the same version 
for everything, they aren't serialisation compatible.

Sorry.

The mvel release is screwed up.

dependency>
   <groupId>org.mvel</groupId>
   <artifactId>mvel</artifactId>
   <version>1.2.24-java1.4</version>
</dependency>

Our mvel, for the 1.4 backport, has always been called mve14 - as we've 
done the releases ourselves in the past.
<dependency>
   <groupId>org.mvel</groupId>
   <artifactId>mvel14</artifactId>
   <version>1.2.21</version>
</dependency>

So now when eclipse does the version stripping it includes mvel.jar and 
not mvel14.jar, leaving it screwed.
