This sample demonstrates how to transform the Android manifest in a meaningful way. It obtains information from the git repository and inserts it into AndroidManifest.xml.
The plugin uses wiredWithFiles(<input>, <output>) to modify the Android public manifest
(SingleArtifact.MERGED_MANIFEST) after it has been merged by standard tasks. The transformation is done with the
InAndOutFileOperationRequest.toTransform() API which is used for objects of type Artifact.Single and
Artifact.Transformable.
The plugin registers three tasks: GitVersionTask.kt which models a task that gets the Git version details of the
project, ManifestTransformerTask.kt which puts the git version in the Android manifest, and
CheckMergedManifestTask.kt to validate the artifact contains the transformed data.
The sample shows how to wire multiple tasks together so that the output of the first task is the input of the second task, and so on. Gradle places these tasks in a task tree to be executed in the proper order during the build.
To run the example, you can just do
./gradlew :app:checkDebugMergedManifest
