Question

I need help with gwteventservice library… Currently, I need to implement push notification for my gwt application. I have found a good library to use, but I got problem when using it with maven (because my existing gwt application using maven). I tried to add the dependency to my gwt project pom.xml, but it keep giving me error at my Eclipse IDE. The error message is :

ArtifactDescriptorException: Failed to read artifact descriptor for
de.novanic.gwteventservice:eventservice-rpc:jar:1.2.0:
UnresolvableModelException: Could not transfer artifact
de.novanic.gwteventservice:parent:pom:1.2.0 from/to remote-repos
(http://XXX.XX.XX.XX:8081/artifactory/remote-repos): No response
received after 60000

I am using artifactory for proxying with online maven repository.
This is the maven dependency tag I have added to my existing gwt project :

        <dependency>
            <groupId>de.novanic.gwteventservice</groupId>
            <artifactId>parent</artifactId>
            <version>1.2.0</version>
        </dependency>
        <dependency>
            <groupId>de.novanic.gwteventservice</groupId>
            <artifactId>eventservice</artifactId>
            <version>1.2.0</version>
        </dependency>
        <dependency>
            <groupId>de.novanic.gwteventservice</groupId>
            <artifactId>eventservice-rpc</artifactId>
            <version>1.2.0</version>
        </dependency>
        <dependency>
            <groupId>de.novanic.gwteventservice</groupId>
            <artifactId>gwteventservice</artifactId>
            <version>1.2.0</version>
        </dependency>

Please help me anyone. Thanks and Regards.

The error that you’re getting tells you that maven can’t find the parent artifact which is the first artifact in the dependency snippet that you posted. The reason for this is that the parent artifact in Maven central only includes a POM with no jar.

Take a look at the Maven docs and you’ll notice that, for dependency blocks in your POM, the default type is jar. So, since you didn’t specify a type, maven is looking for a jar. Since there’s no jar it correctly fails.

If you really want that pom, just add <type>pom</type>. However, it appears that you just need the gwteventservice jars. I would suggest removing the first dependency.
