Theme.AppCompat not found using v7-appcompat APKLIB

Theme.AppCompat not found using v7-appcompat APKLIB

I've added the v4 and v7-appcompat support dependecies into my pom.xml file:
<dependency>
<groupId>android.support</groupId>
<artifactId>compatibility-v7-appcompat</artifactId>
<version>18</version>
<type>apklib</type>
</dependency>
<dependency>
<groupId>android.support</groupId>
<artifactId>compatibility-v7-appcompat</artifactId>
<version>18</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>android.support</groupId>
<artifactId>compatibility-v4</artifactId>
<version>18</version>
</dependency>
And now I want to add the AppCompat style to my activities, but it's not
found. It seems the AppCompat resources have not been loaded from the
APKLIB.
Does anyone know why that's happening?
Thanks!
