Building 1.8.0

This tutorial explains how to build release 1.8.0 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:

export DEPLOY_VERSION=1.8.0
export BUILD_NUMBER=1.8.0-release-345
export KOTLIN_NATIVE_VERSION=1.8.0
export DOCKER_CONTAINER_URL=kotlin.registry.jetbrains.space/p/kotlin/containers/kotlin-build-env:v6

Optional: The docker image can be built locally with the kotlin-build-env.dockerfile file.

docker build --no-cache -t local/kotlin-build-env:v6 -f kotlin-build-env.dockerfile .
export DOCKER_CONTAINER_URL=local/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:

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

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

This generates a ZIP file: dist/kotlin-compiler-1.8.0.zip.

Check that the SHA 256 checksum is equal to the published one for kotlin-compiler-1.8.0.zip:

0bb9419fac9832a56a3a19cad282f8f2d6f1237d2d467dc8dfe9bd4a2a43c42e

Build and verify maven artifacts

export BUILD_NUMBER="1.8.0-release-345(1.8.0)"
docker run --rm -it --name kotlin-build-$DEPLOY_VERSION \
  --workdir="/repo" --volume="$(pwd):/repo" $DOCKER_CONTAINER_URL \
  /bin/bash -c "./scripts/build-kotlin-maven.sh $DEPLOY_VERSION '$BUILD_NUMBER' $KOTLIN_NATIVE_VERSION"
docker run --rm -it --name kotlin-build-repack-zip-with-stable-entries-order-$DEPLOY_VERSION \
  --workdir="/repo" --volume="$(pwd):/repo" $DOCKER_CONTAINER_URL \
  /bin/bash -c "cd build/repo-reproducible && rm reproducible-maven-$DEPLOY_VERSION.zip || true && find . -type f | sort | zip -X reproducible-maven-$DEPLOY_VERSION.zip -@"

This generates a ZIP file: build/repo-reproducible/reproducible-maven-1.8.0.zip.

Check that the SHA 256 checksum is equal to 98573938b708c193ca68c7269d29e6ac777dfe780b3935bc733d4c428a45d4e5.
