The EJB Plugin is capable of generating another artifact aside from the primary one which is EJB. To choose the EJB client as the dependency just specify the type as ejb-client.
The following dependency declaration would include the primary EJB artifact ejb-project-1.0-SNAPSHOT.jar in your project's package.
<project> [...] <dependencies> <dependency> <groupId>com.example</groupId> <artifactId>ejb-project</artifactId> <version>1.0-SNAPSHOT</version> <type>ejb</type> </dependency> </dependencies> [...] </project>
Using the following dependency declaration would instead use the ejb-client artifact ejb-project-1.0-SNAPSHOT-client.jar in your project's package.
<project> [...] <dependencies> <dependency> <groupId>com.example</groupId> <artifactId>ejb-project</artifactId> <version>1.0-SNAPSHOT</version> <type>ejb-client</type> </dependency> </dependencies> [...] </project>
