Building 1.8.20

This tutorial explains how to build release 1.8.20 locally.

Prerequisites

You must have:

Linux or macOS.
Docker installed.
14 GB memory available and configured in Docker.
To get reproducible artifacts, umask command without parameters should produce 0022 or 022 output.

Set environment variables

The following environment variables must be set:

shell

export DEPLOY_VERSION=1.8.20
export BUILD_NUMBER=1.8.20-release-327
export MAVEN_BUILD_NUMBER=1.8.20-release-327\(1.8.20\)
export KOTLIN_NATIVE_VERSION=1.8.20
export DOCKER_CONTAINER_URL=registry.jetbrains.team/p/kt/containers-public/kotlin-build-env:v6

Clone Kotlin repository

In a new folder, clone the release tag from the Kotlin repository, and change directory to the build folder:

shell

git clone --depth 1 --branch v$DEPLOY_VERSION https://github.com/JetBrains/kotlin.git kotlin-build-$DEPLOY_VERSION
cd kotlin-build-$DEPLOY_VERSION

Build and verify the compiler

shell

docker run --rm -it --name kotlin-build-$DEPLOY_VERSION \
  --workdir="/repo" \
  --volume="$(pwd):/repo" \
  --user="$(id -u):$(id -g)" \
  $DOCKER_CONTAINER_URL \
  /bin/bash -c "./scripts/build-kotlin-compiler.sh $DEPLOY_VERSION $BUILD_NUMBER"

This generates a ZIP file: dist/kotlin-compiler-$DEPLOY_VERSION.zip.

Check that the SHA 256 checksum is equal to the published one for kotlin-compiler.zip:

10df74c3c6e2eafd4c7a5572352d37cbe41774996e42de627023cb4c82b50ae4

Build and verify maven artifacts

shell

docker run --rm -it --name kotlin-build-$DEPLOY_VERSION \
  --workdir="/repo" \
  --volume="$(pwd):/repo" \
  --user="$(id -u):$(id -g)" \
  $DOCKER_CONTAINER_URL \
  /bin/bash -c "./scripts/build-kotlin-maven.sh $DEPLOY_VERSION '$MAVEN_BUILD_NUMBER' $KOTLIN_NATIVE_VERSION"

This generates a ZIP file: build/repo-reproducible/reproducible-maven-$DEPLOY_VERSION.zip.

Check that the SHA 256 checksum is equal to cab34569302361c66747691f6f04816b7dd0478e4ede7cea6420931ca953f731.
