I try to use Maven and androidannotations to build my apk, but independently of any IDE (I'm actually using IntelliJ IDEA and not Eclipse, but I would like to have it entirely IDE-independent, so that it would also work perfectly on any build server).
The annotations seem to get processed properly, but they're not being compiled into the apk, which is where I'm currently stuck.
I try to use the <includes>
section in the maven-compiler-plugin
, and the path should be correct - it exists and also contains the annotation processed, generated, java class, which is the Android main activity but with a underscore (_) suffix.
There is a wiki page description how to use Maven+Eclipse, but it's too much bound to the Eclipse IDE. https://github.com/excilys/androidannotations/wiki/Building-Project-Maven-Eclipse so it doesn't help me solve the problem.
This is my pom.xml:

(The complete log of mvn install
is here: http://pastebin.com/6dQkcNXD)
But still running the apk fails with:
E/AndroidRuntime( 6942): Caused by: java.lang.ClassNotFoundException: com.mycompany.myproject.activity.HelloAndroidActivity_ in loader dalvik.system.PathClassLoader
and the annotation processed HelloAndroidActivity_
is not inside the apk / classes.dex.

After further research, I've determined that my original answer was incorrect.
The problem actually lies in the generated .classpath
file. See: https://gist.github.com/cwc/5224145
In that example, broken_cp.xml
causes the processed annotations to not be included in the APK when used as .classpath
. Changing its contents to that of working_cp.xml
and refreshing the project (prompting a build) immediately fixes the APK issue, and I can launch my Android app from Eclipse successfully.
The broken form of the classpath file is regenerated every time I use the Maven > Update Project... project menu option to reload POM files. I'm working around the issue by paying close attention to updates to the .classpath
file, and making sure I don't commit a broken version.

Found the problem: <extensions>true</extensions>
was missing under maven-compiler-plugin
:
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
<includes>
<include>${project.basedir}/target/generated-sources/apt/**</include>
</includes>
</configuration>
<extensions>true</extensions>
</plugin>
