Change maven dependency for artifact using classifier
With the maven jar plugin I build two jar: bar-1.0.0.jar and bar-1.0.0-client.jar.
Actually in my POM I have the following dependency:
<dependency>
<groupId>de.app.test</groupId>
<artifactId>foo</artifactId>
<version>1.0.0</version>
</dependency>
This artifact exist also in two version bar-1.0.0.jar and bar-1.0.0-client.jar
I want to make bar-1.0.0-client.jar dependent of foo-1.0.0-client.jar and bar-1.0.0.jar dependent of foo-1.0.0.jar.
================
->First (wrong) solution: define the scope as provided and use the right foo package when using bar.jar
->Second (long) solution : Add 'server' classifier to the other jar. Use different profile to build the foo artifact and put the classifier in a property.
<dependency>
<groupId>de.app.test</groupId>
<artifactId>foo</artifactId>
<version>1.0.0</version>
<classifier>${profile.classifier}<classifier>
</dependency>
================
Concerning the profile solution.

The problem with this solution is due to the fact that my client interface have some missing interfaces and maven throw a compilation error during the compile phase.
And if I use myapp-model and an other project I didn't not have dependency to the right myapp-interface.
I wonder if it's possible to build a jar and put a specific pom inside ?
Answer
For the Interfaces.
I change nothing and build the both interfaces.jar (client + server).
For the Model I import the both jar as optional
<dependency>
<groupId>com.app</groupId>
<artifactId>myapp-interfaces</artifactId>
<version>${myapp-interfaces.version}</version>
<classifier>client</classifier>
<optional>true</optional>
</dependency>
<dependency>
<groupId>com.app</groupId>
<artifactId>myapp-interfaces</artifactId>
<version>${myapp-interfaces.version}</version>
<classifier>server</classifier>
<optional>true</optional>
</dependency>
With that I can build the both model's version without any error.
In my client application and server application
For each application I create the dependency to the right interfaces.jar and models.jar
