Endpoint client library not recognized

Not sure what happened, but after moving to gradle 3.0.0 rc2, my app module is not recognizing any of the client libraries produced by the endpoint module.

The build can complete w/o any problem with one exception...none of the new API gets picked up by the build.

Here's the dependency section of the gradle file in my app module:

dependencies {
// Gradle dependency check...must be run in the project directory
// ./gradlew -q dependencies app:dependencies --configuration compile

implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation project(path: ':backend', configuration: 'android-endpoints')

Update:

I noticed that the war/jar files are consistently being updated in the backend/build/libs and the zip files are updated as well in backend/build/client-libs.

Update #2:

This occurs with Android Studio 3.0.

Update #3: Apparently, this is a known bug to 3.0 rc2 see here

Update #4 Here's what Google team's suggestion, but I have no idea getting it to work. Anyone?

Solution

  • Here's Google's stand as of Nov 1, 2017: Upgrade the framework to v2.

    They also provided some workarounds (your manager might not like this):

    1. Build the client library manually and copy it over. [Use gradle task : appengineEndpointsGetClientLibs]

    2. Export a pre-built jar and copy it over. [Use gradle task : appengineEndpointsExportClientLibs] NOTE : 2 and 3 will require you to add the google-api-client-lib dependency directly on the android app

    3. Try to use the new plugins that use a different mechanism, while it does automatically add source to your project, this does NOT integrate with Android Studio's UI - so you will have to use gradle/command-line tooling directly for running and deploying: https://github.com/GoogleCloudPlatform/endpoints-framework-gradle-plugin/blob/master/ANDROID_README.md

    I have provide my gradle files in the problem description in case you need a reference.
