[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-1466) please bail if user is using an incompatible MVEL

[ https://issues.jboss.org/browse/JBRULES-1466?page=com.atlassian.jira.plug... ] Geoffrey De Smet resolved JBRULES-1466. --------------------------------------- Resolution: Rejected This is not a good idea: if we hard code the expected MVEL version inside drools if (MVEL.VERSION != "2.0" && MVEL.VERSION_SUB = "17") {...} then we create 2 problems: - drools would crash if a higher, backward-compatible version of mvel is used, for example because another dependency (ZK) needs a more up-to-date mvel version. - maintenance problem to keep that version in sync Furthermore, following the same logic, we'd have to check in drools-compiler if a compatible drools-core version is used. And so on for all modules and all dependencies. Instead, your build system should protect you from the "throw all jars in a lib directory" mess. Use a build system that understand transitive dependencies, such as maven, ant+ivy, gradle, ... -- This message is automatically generated by JIRA.
