Releasing

Change the version in gradle.properties to a non-SNAPSHOT version
Update the CHANGELOG.md for the new release
Update the README.md with the new version
git checkout -b release-X.Y.Z (where X.Y.Z is the new version)
git commit -am "Release X.Y.Z"
git push; make a PR; merge PR
git checkout main && git pull
git tag -a X.Y.Z -m "Version X.Y.Z" (where X.Y.Z is the new version)
Update the gradle.properties to the next SNAPSHOT version (increment patch by 1, e.g. 1.0.0 → 1.0.1-SNAPSHOT)
git commit -am "Prepare next development version"
git push && git push --tags
Visit the GitHub releases page and create a new release, copying the changelog from CHANGELOG.md
Visit the Jitpack site and check that the new release shows up

Publish to local maven repo

Run ./gradlew publishToMavenLocal.
In the other project, add mavenLocal() as a repository (likely in allProjects.repositories of the root build.gradle file).
Update com.ryanmoelter.magellanx:magellanx-compose:X.Y.Z to com.ryanmoelter.magellanx:magellanx-compose:SNAPSHOT_VERSION, where SNAPSHOT_VERSION is the VERSION_NAME defined in this project's ./gradle.properties.

the Jitpack site provides builds for each branch. They take a while to build, so for quick iteration I recommend using mavenLocal as shown above.

Push a branch to this repo
Update your dependency version to {branch-name}-SNAPSHOT, where {branch-name} is your branch's name
Wait for Jitpack to build, which might take ~10 minutes
