Gradle Update keeps the latest Gradle Wrapper by pull requests for your repositories on GitHub.

Note: In past adding a star on this repository triggered a new pull request, but it has no effect now. Feel free to star this repository!

How works

When a user requested update for a repository

1. Receive a request for repository.
2. Check if user have permission to push to the repository.
3. Check if Gradle Update have permission to pull from the repository.
4. Queue a task for the repository.
5. In a task,
6. Check if the repository:default-branch does not have the latest version of Gradle Wrapper.
7. Fork the repository as fork and sync default-branch to upstream.
8. Create or update a commit with the latest version of Gradle Wrapper as fork:gradle-branch.
9. Create or update a pull request from fork:gradle-branch onto repository:default-branch.

Periodically

1. Check the latest version of Gradle from services.gradle.org.
2. If a new version of Gradle is found,
3. Trigger updating Gradle Wrapper on latest-gradle-wrapper.
4. Wait until the new version is available on latest-gradle-wrapper.
5. Get a list of repositories to be updated and queue tasks for each repository.

When a badge for the repository is requested,

1. Check the version of Gradle Wrapper in the repository.
2. If it is up-to-date, respond the green image.
3. If it is out-of-date, respond the red image.
4. If it has no Gradle Wrapper, respond the grey image.

How to Run

Build and run App Engine development server.

npm run watch
./gradlew appengineRun

We can run Webpack development server instead.

npm run start

How to Deploy

Push the master branch and Circle CI will deploy the app to App Engine.

A service account key should be provided during CI. Open Google Cloud Platform Console and create a service account. Then, encode the JSON key as follows and store it into the environment variable APPENGINE_KEY on Circle CI.

base64 -b0 appengine-key.json
