title: Updating a maven library project into main project (android)
body: <p>i'm trying to understand Maven Android Plugin with the examples found here: <a href="https://github.com/jayway/maven-android-plugin-samples/archives/stable" rel="nofollow">https://github.com/jayway/maven-android-plugin-samples/archives/stable</a></p>
  
  <p>I'm using the example "libraryproject" and all is working good, only one thing i really can't figure out: if i change something into the lib1 project (example the content of the resource file) and complile the main project, i still see in the generated apk file the old resources.</p>
  
  <p>I tryed to clean, rebuild, no change in my apk...</p>
  
  <p>Sorry for the stupid question end for my bad english.</p>
  
  <p>EDIT: i just did like said by yorkw:</p>
  
  <p>But now i receive the following error:</p>
