Sample repo to reproduce the issue with uploading Proguard mapping file to AppDynamics automatically

Link to the original issue thread reported to AppDynamics

The project is based on standard project generated automatically by Android Studio.

AppDynamics version 21.5.0

I have updates sample project to latest Android Gradle plugin (4.2.1) and latest AppDynamics version (21.5.0) After updating to 21.5.0 the issue is fixed, but there is a blocker for using it straight away. After bumping AD version, below error appears: "Cannot get property 'buildID' on extra properties extension as it does not exist" This field is not described anywhere in official docs, so looks like plugin devs just shipped in public API some internally used field. It fails builds if AD is enabled. It can be easily workarounded (with unknown side effects) by adding below line to app/build.gradle project.ext.buildID = "any non empty text"

After this is added project compiles and mapping file is automatically uploaded (checked via API)

But after bumping the plugin new issue appeared in our main app (do not how to reproduce this on sample):

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:appDynamicsProcessProguardMappingIgUsRelease'.

AppDynamics version 20.12.1

Then AppDynamics adeum Gradle plugin was applied to it:

1. Root build.gradle - classpath with version 20.12.1 added
2. app/build.gradle - adeum plugin applied and configured
3. TestApp - Android Application class with enabling AppDynamics instrumentation

Setup

Just add license configuration and AppDynamics app key to app/build.gradle to make the project compilable (all of them are marked as with //TODO in the file)

Initial investigation

From what I see there are 2 issues:

1. proguardMappingFileUpload.failBuildOnUploadFailure does not work, because the build is never failed if the file is not uploaded

proguardMappingFileUpload {
        failBuildOnUploadFailure true
        enabled true
    }

2. The mapping file is not uploaded

From what I see the issue is in the AppDynamics Gradle plugin itself - the task for uploading is called way before the file itself is generated. Here is the snipped from build logs for ./gradlew assembleDebug command:

As you can see :app:appDynamicsUploadProguardMappingDebug called too early

Running the task second time with assumption that it will try to upload already generated file also does not work, because the task is considered UP-TO-DATE :)
