Welcome to Kotlin!
It is an open-source, statically typed programming language supported and developed by JetBrains and open-source contributors.
Some handy links:
Support for multiplatform programming is one of Kotlin’s key benefits. It reduces time spent writing and maintaining the same code for different platforms while retaining the flexibility and benefits of native programming.
This repository is using Gradle toolchains feature to select and auto-provision required JDKs from AdoptOpenJdk project.
Unfortunately AdoptOpenJdk project does not provide required JDK 1.6 and 1.7 images, so you could either download them manually and provide path to installation via JDK_16
and JDK_17
environment variables or use following SDK managers:
Alternatively, it is still possible to only provide required JDKs via environment variables (see gradle.properties for supported variable names). To ensure Gradle uses only JDKs from environmental variables - disable Gradle toolchain auto-detection by passing -Porg.gradle.java.installations.auto-detect=false
option (or put it into $GRADLE_USER_HOME/gradle.properties
).
For local development, if you‘re not working on the standard library, it’s OK to avoid installing JDK 1.6 and JDK 1.7. Add kotlin.build.isObsoleteJdkOverrideEnabled=true
to the local.properties
file, so build will only use JDK 1.8+. Note, that in this case, build will have Gradle remote build cache misses for some tasks.
Note: The JDK 6 for MacOS is not available on Oracle's site. You can install it by
$ brew tap homebrew/cask-versions $ brew install --cask java6
On Windows you might need to add long paths setting to the repo:
git config core.longpaths true
The project is built with Gradle. Run Gradle to build the project and to run the tests using the following command on Unix/macOS:
./gradlew <tasks-and-options>
or the following command on Windows:
gradlew <tasks-and-options>
On the first project configuration gradle will download and setup the dependencies on
intellij-core
is a part of command line compiler and contains only necessary APIs.idea-full
is a full blown IntelliJ IDEA Community Edition to be used in the plugin module.These dependencies are quite large, so depending on the quality of your internet connection you might face timeouts getting them. In this case, you can increase timeout by specifying the following command line parameters on the first run:
./gradlew -Dhttp.socketTimeout=60000 -Dhttp.connectionTimeout=60000
clean
- clean build resultsdist
- assembles the compiler distribution into dist/kotlinc/
folderinstall
- build and install all public artifacts into local maven repositorycoreLibsTest
- build and run stdlib, reflect and kotlin-test testsgradlePluginTest
- build and run gradle plugin testscompilerTest
- build and run all compiler testsTo reproduce TeamCity build use -Pteamcity=true
flag. Local builds don't run proguard and have jar compression disabled by default.
OPTIONAL: Some artifacts, mainly Maven plugin ones, are built separately with Maven. Refer to libraries/ReadMe.md for details.
To build Kotlin/Native, see kotlin-native/README.md.
Working with the Kotlin project requires at least IntelliJ IDEA 2019.1. You can download IntelliJ IDEA 2019.1 here.
After cloning the project, to import the project in IntelliJ choose the project directory in the Open project dialog. Then, after project opened, select File
-> New
-> Module from Existing Sources...
in the menu, and select build.gradle.kts
file in the project's root folder.
In the import dialog, select use default gradle wrapper
.
To be able to run tests from IntelliJ easily, check Delegate IDE build/run actions to Gradle
and choose Gradle Test Runner
in the Gradle runner settings after importing the project.
At this time, you can use the latest released 1.6.x
version of the Kotlin plugin for working with the code. To make sure you have the latest version installed, use Tools
-> Kotlin
-> Configure Kotlin Plugin Updates
.
For handy work with compiler tests it's recommended to use Kotlin Compiler Test Helper
We have a dependencies verification feature enabled in the repository for all Gradle builds. Gradle will check hashes (md5 and sha256) of used dependencies and will fail builds with Dependency verification failed
errors when local artifacts are absent or have different hashes listed in the verification-metadata.xml file.
It's expected that verification-metadata.xml
should only be updated with the commits that modify the build. There are some tips how to perform such updates:
./gradlew -M sha256,md5 help
(any other task may be used instead of help
)
origin
attribute (instead of Generated by Gradle
) if you did some manual verification of the artifact.also-trust
tag has to be added.darwin
, mac
, osx
, linux
, windows
), remember to add counterparts for other platforms.We publish -dev
and -SNAPSHOT
versions frequently.
For -dev
versions you can use the list of available versions and include this maven repository:
maven { url = uri("https://maven.pkg.jetbrains.space/kotlin/p/kotlin/bootstrap") }
For -SNAPSHOT
versions that are updated daily, you can use the list of available versions and include this maven repository:
maven { url = uri("https://oss.sonatype.org/content/repositories/snapshots/") }
