How to build a JAR for an android project

I am working on a small project to allow cookies to persist. I want to make the project as a JAR so other developers can use it in there project. At the moment I am able to build the project as an APKLIB however this seems unnecessary as the resources are not needed. If I change the packaging to JAR I get the follow error when building

Results :

Tests in error:
shouldAddCookie(com.doward.persistantcookietest.PersistantCookieStoreTest): java.lang.ClassNotFoundException: caught an exception while obtaining a class file for com.doward.persistantcookies.R
shouldClearAllCookies(com.doward.persistantcookietest.PersistantCookieStoreTest): java.lang.ClassNotFoundException: caught an exception while obtaining a class file for com.doward.persistantcookies.R
shouldClearExpired(com.doward.persistantcookietest.PersistantCookieStoreTest): java.lang.ClassNotFoundException: caught an exception while obtaining a class file for com.doward.persistantcookies.R

The POM looks like this

If you have a andorid project and you wish to use the same in another project you can make the project as a library project and refer the same in another Android project. This can include your resources also.

http://developer.android.com/tools/projects/projects-eclipse.html

You export your utility classes that do not refer to resources in android ie pure java classes. If you use eclipse you can have a look at the tutorial below

If you want to just build a JAR file from .class files and no resources e.g. no XML files releating to layouts, values, colours etc then you can do so from the command line:

jar -cvf <filenameorjar.jar> <files to be included>

Example:

jar -cvf cookiepersist.jar com/*

This will create a jar file in the present working directory and include all the .class files from the directory com in the present working directory.
