Check your gradle-wrapper jar's checksum on CI. This is particularly useful for OSS projects.
- A Unix-like operating system: macOS, Linux, BSD. This may work on Windows, but I've not tested it.

wgetif you want to download via wget (more below)
It expects to be run from the root project directory, with gradle-wrapper.properties and gradle-wrapper.jar located in the conventional relative "gradle/wrapper" subdirectory of the root project directory. It expects the distribution to be "all" and not "bin".
- <rootProjectDir> - gradle - wrapper | gradle-wrapper.jar | gradle-wrapper.properties
My bash-fu isn't great and I'm sure this could be improved. PRs are also welcome to support more configuration (custom gradle-wrapper jar/properties locations, bin vs all, etc).
The script is executed by running one of the following commands in your terminal. You can do this via the command-line with either
wget. The script should be run from your gradle project's root directory.
Note: for the
sh calls below, you may need to use
bash directly if your CI environment's
sh version doesn't support functions, such as on Travis-CI.
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ZacSweers/check-gradle-checksums/master/check-gradle-checksums.sh)"
sh -c "$(wget -O- https://raw.githubusercontent.com/ZacSweers/check-gradle-checksums/master/check-gradle-checksums.sh)"
It's a good idea to inspect the install script from projects you don't yet know. You can do that by downloading the install script first, looking through it so everything looks normal, then running it:
curl -Lo check-gradle-checksums.sh https://raw.githubusercontent.com/ZacSweers/check-gradle-checksums/master/check-gradle-checksums.sh sh check-gradle-checksums.sh
If you want to only use a fixed version, you can use a fixed sha in the link above.
For idempotent builds, you should use a fixed version like the above. This repo will never rewrite git history.
