build.gradle and project libs

Question

I have a project in android studio that uses a project library. My problem is the configuartion of the gradle files.

I really tried a lot of solution that were posted here (define modul in project lib in settings as modul, sherlock example, setting right sourcesets ...), but I always get the same error (as soon as I add the lib debendency to my apps build.gradle file):

A problem occurred configuring project ':MyApp'.
> Failed to notify project evaluation listener.
   > Configuration with name 'default' not found.

I already did a clean and build from command line, but this has no effect. Is it possible that this is just a bug in the early version of Android Studio (like the comment in this post)? Or do I miss something?

My current Android Studio Version: 0.1.6 and my OS: Windows 7, 64bit

Please help me, I'm new to gradle and I never used maven or ant before.

Answer 1

I think you are specifying the path to your library project incorrectly. If I'm interpreting your project layout correctly the line should be the following:

compile project(':MyApp:libraries:projectLib')

When you start a project path with ':' you are making an absolute path from the root project and then basically just writing a path with ':' instead of '/'. In this case your projectLib module is in the directory MyProject/MyApp/libraries/projectLib, and MyProject is where your settings.gradle is, making it your root project. So swapping in colons for slashes gets you the line I wrote above.

You'll need to modify your settings.gradle to include the full path as well:

include 'MyApp:libraries:projectLib'

Finally, if you want to save some typing for stuff like your repository configuration you can put it in an allproject block in your root project.

allprojects {
    repositories {
        mavenCentral()
    }
}

A lot of nice little tips like that covered in the multi-module docs.
