You will have to add the war as a dependency to the project too, not only in the plugin configuration.
<project ...>
<modelVersion>4.0.0</modelVersion>
<groupId>com.syril.administration</groupId>
<artifactId>UserAdminEAR</artifactId>
<version>YOUR_VERSION_HERE</version>
<packaging>ear</packaging>
<dependencies>
<!-- some other dependencies here -->
...
<!-- Here is the dependency to the war that is referenced in the ear plugin -->
<dependency>
<groupId>com.syril.administration</groupId>
<artifactId>UserAdmin</artifactId>
<version>YOUR_VERSION_HERE</version>
<type>war</type>
</dependency>
</dependencies>
...
</project>
Edit
The <webModule/> artifact is not in your <dependencies/> list. That is what I was suggesting.
Add the following:
<dependency>
<groupId>com.syril.service</groupId>
<artifactId>UserAdminSL</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>war</type>
</dependency>
OR
Change the <webModule/>:
<webModule>
<groupId>com.syril.service</groupId>
<artifactId>UserAdminService</artifactId>
<contextRoot>/UserAdminSL</contextRoot>
</webModule>
That is of course if UserAdminService is the same as UserAdminSL which I think.
