With Piwai suggestion I've solved this problem by moving to snapshot builds of android annotations. In order to switch to snapshots replace in your pom.xml current AA dependencies with:
<dependency>
<groupId>com.googlecode.androidannotations</groupId>
<artifactId>androidannotations</artifactId>
<version>2.7-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.googlecode.androidannotations</groupId>
<artifactId>androidannotations-api</artifactId>
<version>2.7-SNAPSHOT</version>
</dependency>
also you'll need to add snapshot repository:
<repositories>
<repository>
<id>snapshots-repository</id>
<name>Sonatype oss snapshot repo</name>
<url>https://oss.sonatype.org/content/repositories/snapshots</url>
</repository>
</repositories>
NOTE: from AA v.2.7 release notes:
the API jar is now a separate artifact, androidannotations-api. We do not use the api classifier any more.
