class rocks.xmpp.websocket.model.Open nor any of its super class is known to this context.

Issue #73 closed
Cory Redmond created an issue

I can't see anything wrong with the build of my project, the class exists, and is shaded by maven properly.

Here's the stacktrace when I run the app

    Hi,

    I am not sure, what you are doing with the shade plugin here, but I've used it as well to create a "super-jar" which contains all classes from all dependencies.

    I use java.util.ServiceLoader to "collect" the classes from different jars and make them known to JAXB. Despite the class is on the classpath it's probably not recognized by JAXB because ServiceLoader works by looking up a file called rocks.xmpp.core.session.Module (the interface name) in a JAR's META-INF/services folder.

    If multiple jars get merged together into one by the shade or assembly plugin, they override each others file and only take the last one, so ServiceLoader only finds one file instead of multiple.

    It can be solved by using a transformer:

    <transformers>
    <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer">
    </transformer>
</transformers>

    You can also have a look here, where I've used it:

    https://bitbucket.org/sco0ter/babbler/src/831c81dbdca29665fd637734f7f728b7955bc757/xmpp-documentation/pom.xml?at=master&fileviewer=file-view-default#pom.xml-100

    Hope it helps.

    Fantastic! Thanks a lot.

    It came across my mind that the meta-inf was pretty empty, guess I just passed it off as stupid, I'll keep that in mind! <3
