Gradle

Plugins

1. Axion plugin

   We are using Gradle's axion-release plugin for release & version management.

   If current commit is tagged commit, project has a release version( i.e., 0.1.0). If there were any commits after last tag, project is in SNAPSHOT version( i.e., 0.1.1-SNAPSHOT).

   axion-release follows the structure of git, only knows about tags on given branch.

Usage

first time generating a new library project

gradle init --type kotlin-library --dsl kotlin

Options for all gradle commands: -D or --system-prop, -P or --project-prop, -m or --dry-run

Check Task Dependencies With a Dry Run with dryRun: -m or --dry-run i.e., gradle publish -m

Version

display computed version

gradle cV
gradle currentVersion
# to get version # as plain text
export VERSION=$(gradle cV -q -Prelease.quiet)
echo $VERSION

Verification

gradle test
gradle jacocoTestReport
gradle jacocoTestCoverageVerification
gradle sonarqube
gradle check

# disable all checks for current release
gradle release -Prelease.disableChecks -Prelease.dryRun
# real release
gradle release -Prelease.customUsername=sxc460 -Prelease.customPassword=
# bump Minor Version : 0.1.0 -> 0.2.0
gradle markNextVersion -Prelease.incrementer=incrementMinor -Prelease.dryRun
# in CI enveroment 
gradle release -Prelease.disableChecks -Prelease.pushTagsOnly -x test --profile

Changelog

With every release, run git-chglog

# first time
git-chglog --init
# on release branch, generate CHANGELOG.md and commit before merging back to develop & master.
git-chglog  -o CHANGELOG.md
git-chglog  -o CHANGELOG.md -next-tag 2.0.0

Publish

publish after release

gradle publish
# skip tests in CI
gradle publish -x test --profile
gradle build publish -Prelease.forceSnapshot
gradle build publish -Prelease.forceVersion=3.0.0
CI=true GITHUB_USER=xmlking GITHUB_TOKEN=<GITHUB_NPM_TOKEN> gradle publish

Docker

# Build an image tarball,
# then you can load with `docker load --input build/jib-image.tar`
gradle jibBuildTar
# Build and publish docker image
gradle jib
# Build image locally useing your Docker daemon (on publish)
gradle jibDockerBuild

local testing

pull a remote image and locally use it as base image

# pull base image first
docker pull gcr.io/distroless/java:11
# use local docker image as base, build image only (on publish)
gradle jibDockerBuild -PbaseDockerImage=docker://gcr.io/distroless/java:11
# you can run your local docker image
docker run -it xmlking/micro-apps-demo:1.6.1-SNAPSHOT

Dependencies

# Report dependencies
gradle dependencyUpdates -Drevision=release -DoutputFormatter=json,xml
# Update dependencies, `dependsOn dependencyUpdates`
gradle useLatestVersions
# This task will succeed if all available updates were successfully applied by useLatestVersions
gradle useLatestVersions && gradle useLatestVersionsCheck

# upgrade gradlew
# upgrade project gradle version
gradle wrapper --gradle-version 6.2.2 --distribution-type all
