Android Deps Repository Generator

Tool to generate a gradle-specified repository for Android and Java dependencies.

Usage

fetch_all.sh [--help]

For each of the dependencies specified in build.gradle, the above command will take care of the following tasks:

• Download the library
• Generate a README.chromium file
• Download the LICENSE
• Generate a GN target in BUILD.gn
• Generate .info files for AAR libraries
• Generate CIPD yaml files describing the packages

Adding a new library

Full steps to add a new third party library:

1. Add dependency to build.gradle
2. Run fetch_all.sh
3. Upload the new and updated packages via cipd. The script from step 2 should provide hints for this step when it successfully completes.
4. Create a commit & follow //docs/adding_to_third_party.md for the review.

Implementation notes:

The script is written as a Gradle plugin to leverage its dependency resolution features. An alternative way to implement it is to mix gradle to purely fetch dependencies and their pom.xml files, and use Python to process and generate the files. This approach was not as successful, as some information about the dependencies does not seem to be available purely from the POM file, which resulted in expecting dependencies that gradle considered unnecessary.
