Maven Module Project not found

Question

I've a multi module maven project. I'm trying to access the content of a module from another module. Maven gives me this error.

Could not resolve dependencies for project net.twerion:wrapper:jar:1.0-SNAPSHOT: Failed to collect dependencies at net.twerion:cloud.packets:jar:1.0-SNAPSHOT: Failed to read artifact descriptor for net.twerion:cloud.packets:jar:1.0-SNAPSHOT: Could not find artifact net.twerion:cloud:pom:1.0-SNAPSHOT

The Module wrapper is the compiled module, packets the accessable module and cloud the project.

Please help me.

Your first pom references the wrong artefact id. Instead of

<dependency>
    <groupId>net.twerion</groupId>
    <artifactId>cloud.packets</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

you should be using

<dependency>
    <groupId>net.twerion</groupId>
    <artifactId>packets</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

Then it should work.
