I'm concluding that it is not an Eclipse plugin - If I recall correctly, it is an "osgi" bundle intended to be used as such, not within the Eclipse environment. > 2nd question: does it need to be added to any "feature" set? if so, > which one? > Because it's not part of Eclipse plugins, it doesn't need to be added to any Eclipse feature, as far as I can determine. > This project builds a jar which contains two jars: > apache-activemq-4.1.1.jar and geronimo-jms_1.1_spec-1.0.jar, both of > which have versions of the javax.jms.ConnectionFactory. > > I don't think it actually builds a jar containing both of these. Instead, it appears to "flatten" all the jars so no "jars" appear inside of the main Jar, just all the classes. This is done using the felix maven bundle directive <Embed-Dependency>*;scope=compile;inline=true</Embed-Dependency>. If you remove the inline=true, then it does build a Jar containing the 3 uima-as jars plus the apache-activemq-4.1.1 jar and the spring-2.0.6 jar. (Caution: I'm not totally 100% sure that's what's happening, because I've been fiddling with the POM and haven't restored it to its original state - please post if this is incorrect) > 3rd question: how to resolve this so that identical class names here > don't cause issues? > > No need to resolve as far as I know. -Marshall
