[jboss-jira] [JBoss JIRA] (DROOLS-3277) KieScanner in Scala fat-jar application does not work due to Plexus configuration

KieScanner in Scala fat-jar application does not work due to Plexus configuration --------------------------------------------------------------------------------- Key: DROOLS-3277 URL: https://issues.redhat.com/browse/DROOLS-3277 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.13.0.Final Reporter: Michael Reynolds Assignee: Mario Fusco Priority: Major Attachments: components.xml, out.log The configuration required for all the KIE related components wired together with Sisu and in Plexus is spread out among many files with the same name/location in various library jars. The SBT assembly plugin is the standard for building a Scala fat-jar application. When it multiple versions of the same file when squashing the jars together it attempts to apply a merge strategy to them. For the Sisu configuration, it is simple enough to apply a "concat" merge strategy. However, the META-INF/plexus/components.xml cannot be automatically merged. Unless all the elements are present, various component lookups will fail when using the KieScanner. I've provided the following attachments related to this case: ||File||Description|| |out.log|Output of starting the fat-jar application without properly merging the Sisu and Plexus configuration files| |components.xml|The merged components.xml file I created that resolves this issue.|
