Android: building with Gradle, signing with maven

My Android build works fine in Continuous Integration, except for androidSigning: Gradle can allow for a developer to catch the keystore path and passwords in clear. Which is not satisfactory.
1- Have you a workaround for that? Such as password encryption...
2- My idea is now to build with Gradle, and sign and zipalign with Maven.
Currently I succeed in signing an existing apk, but cannot zipalign the signed apk. Here is the pom.xml located in the app folder:
<profiles>
<profile>
<id>sign</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jarsigner-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<id>signing</id>
<goals>
<goal>sign</goal>
</goals>
... all parameters ok...
</execution>
</executions>
</plugin>
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<version>3.8.2</version>
<inherited>true</inherited>
<configuration>
<sign>
<debug>false</debug>
</sign>
<zipalign>
<verbose>true</verbose>
<inputApk>${apk.build.directory}/app-release-unsigned.apk</inputApk>
<outputApk>${apk.build.directory}/app-release-signed-aligned.apk</outputApk>
<skip>false</skip>
</zipalign>
</configuration>
<executions>
<execution>
<id>alignApk</id>
<phase>package</phase>
<goals>
<goal>zipalign</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
Results is
[INFO] --- maven-jarsigner-plugin:1.4:sign (signing) # mavensigning ---
[INFO] 1 archive(s) traitées
[INFO]
[INFO] --- android-maven-plugin:3.8.2:zipalign (alignApk) # mavensigning ---
[INFO] Skipping zipalign on pom
Any idea why I cannont perform zipalign?

App can be built with maven, but not as Android application

I have an Android project which I ¨mavenized¨ (Configure > Convert to Maven Project) using the M2E - Maven Integration for Eclipse.
The project uses a google play services library, which was transformed into an apklib. I added this dependency to my project (to my pom.xml). I have to mention that the pom was build automatically, but I replaced it with the one generated by :
mvn help:effective-pom
After that I did a clean install and built the project with maven, having the following goals in run config:
clean install -Dandroid.sdk.path="path to my sdk" android:deploy android:run
Everything works fine, but I have errors in my project(so I can't run it as an Android app). It looks like everything related to the google library is not recognized.
My pom.xml looks like this:

I guess that right now Maven is working fine, but there is a problem with Android.
Any suggestions?

The Eclipse ADT does not support the Maven archive format for apklib dependencies. In order for this to successfully compile in Eclipse you need to have the full source of a "Mavenised" (i.e. contained a POM with matching Maven coordinates to the dependency declared in your app POM) Android Library project imported into your Eclipse workspace.

Maven plugin error in Eclipse

I am writing POM.xml file for Android app and I constantly get an error. It appears after I use Maven plugin in Eclipse (Project->properties->Configure->Convert to Maven). I put an error below the code.

Installing the Android Connector for Maven Eclipse should resolve this issue.

NetBeans does not recognize classes in apklib (ActionBarSherlock for instance)

I'm working on an Android app in NetBeans 7.3 (because it's my preferred IDE).
It's a Maven project, it has a dependency on ActionBarSherlock and I'm using the android-maven-plugin.
My POM is similar to this one:

Everything works fine until I actual want to use the ActionBarSherlock library.
NetBeans does not seem to recognize the classes in the apklib (for example com.actionbarsherlock.app.SherlockActivity).
I can find the apklib in the tree structure of the project in NetBeans, but it's filed under Non-classpath Dependencies.
It does recognize the generated sources of the library (like com.actionbarsherlock.R).
How can I fix this, so that NetBeans does not complain about classes not being found and so that auto-completion works for these classes?
I tried several possible workarounds (1, 2, 3), but they were not working for me.
Also I'm pretty sure NetBeans bug 220446 is related

You should install nbandroid modules which should be able to handle the android classpath for you. http://www.nbandroid.org/

Why mvn android:lint skips sub modules?

Why does android:lint only scans my Aggregator Project for Lint warnings and skips the "APP" Module ?
In the POM of the APP Module i defined:
<plugins>

<artifactId>android-maven-plugin</artifactId>

Cheers

I do not think we have implemented it to work in a multi module build this way. However you can just configure the plugin in the aggregator and the execution in the apk project and it will work.
