[rules-users] Drools 5.3 is not working in a OSGi tycho building

I've tried unsuccessfully to upgrade my osgi application to jbpm 5.2 and Drools 5.3. I'm using tycho and I got this error: [ERROR] Missing requirement: org.drools.core 5.3.1.Final requires 'bundle org.drools.api 5.3.1.SNAPSHOT' but it could not be found Its worth to say that with Jbpm 5.1 and Drools 5.2 everything is ok. Looking at the org.drools.core pom's I could see that the problem seems to be this: <Require-Bundle>org.drools.api;visibility:=reexport;*bundle-version="${drools.osgi.version}"*</Require-Bundle> *So ${drools.osgi.version} *is being resolved to 5.3.1.SNAPSHOT that is not being resolved because .SNAPSHOT is not a valid OSGI word as the .qualifier is. regards Cristiano
