Question

I am trying to get working R.java generation to project in gen folder. Actually, the application builds, when using maven build, however eclipse finds error, because it can’t resolve R.java file (which actually is being put in /target/generated-sources/r/R.java location after each build). What is the suggested way to solve the problem?

Answer 1

The recommended way is to use the Maven Integration for Android Development Tools and the Maven Android Plugin provides instructions. From the Eclipse Integration page:

Introduction

Android’s official development effort
provides solid support for Eclipse
integration, and we’d like to make
sure maven-android-plugin helps bridge
Maven, Android, and Eclipse. This page
will help us collect information on
what works and doesn’t work

The solution

To make maven-android-plugin work well
in Eclipse with ADT, this is what you
need:

1. Go to the M2Eclipse Android Integration project page and
   install the tools listed under
   Requirements.
2. Of course, set up update-site url and install the M2Eclipse Android
   Integration plugin in Eclipse. * Get
   version 0.2.2 or later. It should be
   under the category ‘Maven Integration
   for Android Development Tools’.
3. In Eclipse, to bring in your Maven Android projects, choose File ->
   Import… -> Maven -> Existing Maven
   Projects.

So jump to the M2Eclipse Android Integration project page and then to the Getting Started guide for very detailed instructions.

With the right tooling, the directory of the generated code should be added automatically as source directory under Eclipse.
