GitOps version

• Generate a version from git tags and commits
• Version is cached in a file to avoid expensive git operations
• Schema is based on semver
• Compatible with gitflow
• Portable, works on Linux and Windows

In a nutshell

Version are generated from git tags and commits. Format is "[major].{minor}.[patch]-[commit amout since last tag].[commit id]+[timestamp]".

Timestamp is only added if the version is not cached. Timestamp is added to avoid integrity issues when executing the script multiple times.

Gradle (Java, Kotlin, Groovy, Scala, C/C++, JavaScript)

In your build.gradle:

if (project.hasProperty('projVersion')) {
  project.version = project.projVersion
} else {
  project.version = 'unknown'

# Build a Gradle project with the version
❯ gradle -PprojVersion=$(sh version.sh -g . -m -c) build
