Why Versioning Matters

A clear version on every artifact tells consumers what changed and lets you roll back safely. Manual edits to a version string are error prone, so we automate them.

Setting the Project Version

Every Gradle project has a version property used to name published artifacts.

version = "1.4.0"
group = "com.acme"

Semantic Versioning

SemVer uses MAJOR.MINOR.PATCH:

MAJOR: breaking changes
MINOR: new backward-compatible features
PATCH: backward-compatible fixes

SNAPSHOT vs Release

A -SNAPSHOT suffix marks an in-development build that may change. Releases drop the suffix and are immutable once published.

version = "1.5.0-SNAPSHOT"

Deriving Version from Git

Many teams compute the version from the latest Git tag so the source of truth is the repository history, not a hard-coded string.

version = providers.exec {
    commandLine("git", "describe", "--tags")
}.standardOutput.asText.get().trim()

A Release Task

Wrap the steps of a release into a single task that depends on build, tag, and publish.

tasks.register("release") {
    dependsOn("build", "publish")
}

Tagging in Git

An annotated tag records the released version in history.

git tag -a v1.5.0 -m "Release 1.5.0"
git push origin v1.5.0

Bumping the Version

After a release, bump to the next SNAPSHOT so further commits are clearly pre-release. Plugins like Axion or the release plugin automate this.

Reproducible Builds

Pin dependency versions and avoid dynamic ranges so the same source always produces the same artifact, an essential property for trustworthy releases.

implementation("com.google.guava:guava:33.0.0-jre")

Wiring into CI

In CI, run the release task only on tagged commits or a protected branch, so accidental pushes never publish.

if [ "$CI_COMMIT_TAG" ]; then gradle release; fi

Best Practices

Keep releases predictable:

One source of truth for the version
Never republish an existing release version
Automate tagging and the version bump

Quick Check

Test your understanding of release versioning.

Recap

You learned release automation:

Use SemVer for MAJOR.MINOR.PATCH
SNAPSHOT for dev, plain version for releases
Derive version from Git tags
Wrap build+tag+publish into a release task gated in CI
