Building 1.7.21

This tutorial explains how to build release 1.7.21 locally.

Prerequisites

You must have:

  • Linux or MacOS.
  • Docker installed.
  • 14 GB memory available and configured in Docker.

Set environment variables

The following environment variables must be set:

export DEPLOY_VERSION=1.7.21
export BUILD_NUMBER=1.7.21-release-272
export KOTLIN_NATIVE_VERSION=1.7.21
export DOCKER_CONTAINER_URL=kotlin.registry.jetbrains.space/p/kotlin/containers/kotlin-build-env:v5

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

Download and save scripts/build-kotlin-compiler.sh to thescripts folder in your repository, and then execute it in a docker container:

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-1.7.21.zip.

Check that the SHA 256 checksum is the same as the ZIP file published on GitHub: 8412b31b808755f0c0d336dbb8c8443fa239bf32ddb3cdb81b305b25f0ad279e

Build maven artifacts

Download and save scripts/build-kotlin-maven.sh to the scripts folder in your repository, and then execute it in a docker container:

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"

This generates a ZIP file: build/repo-reproducible/reproducible-maven-1.7.21.zip.

Note: Instructions for checking reproducibility will be covered in the upcoming release. There are already many JAR files on Maven central that are reproducible with this tutorial.
