Android: ANT build fails with google-play-services-lib: "resolve to a path with no project.properties file for project"

Question

I'm trying to build my apps using ANT and I'm failing miserably after I included the google-play-services-lib library project.

Step 1

I set up a reference to the library project in my project.properties file:

android.library.reference.1=/path/to/google-play-services_lib

Step 2

I ran these commands inside the google-play-services_lib folder:

android update lib-project --path .
ant clean
ant release

BUILD SUCCESS!

Step 3

Back to my project folder

ant clean
ant release

ERROR

BUILD FAILED
/android/tools/ant/build.xml:460: /path/to/google-play-services_lib resolve to a path with no project.properties file for project /my/project-folder

There IS a project.properties in both folders, naturally. The one in google-play-services_lib contains this code:

target=android-8
android.library=true

I'm obviously missing something that's right there in front of me and I'd really appreciate your help. Thanks!

Answer 1

Try changing the android library reference to a relative path (relative to the current directory) instead of an absolute path.

e.g.

android.library.reference.1=../../../relative_path/to/google-play-services_lib
