Maven

"kotlin-maven-plugin" compiles Kotlin sources and modules.
Note: only Maven 3 is supported for now.

The old "kotlin-maven-plugin" is no longer supported.

Repositories

Kotlin maven artifacts are published on http://repository.jetbrains.com.

Add references to it in your pom or settings file:

Versions

Define Kotlin version in kotlin.version. Possible values are:

• X.Y-SNAPSHOT - snapshot versions for X.Y release, updated with every successful build on our continuous integration server.
  Highly unstable, recommended for testing new compiler features.
  Currently, all builds are published as 0.1-SNAPSHOT.

• X.Y.Z - release or milestone version X.Y.Z, updated manually, stable.

Here's the table of versions corresponding to milestone codes:

Dependencies

Kotlin has an extensive standard library, use it in your program:

Compile Kotlin sources

Specify source directories in <build> tag:

Reference kotlin-maven-plugin to compile sources:

Compile mixed Kotlin/Java sources

To compile mixed code applications Kotlin compiler should be invoked before Java compiler.
In maven terms that means kotlin-maven-plugin should be run before maven-compiler-plugin.

It could be done by moving Kotlin compilation to previous phase, process-sources (feel free to suggest a better solution if you have one):

Gradle

"kotlin-gradle-plugin" (available since Kotlin M5.2) compiles Kotlin sources and modules.

Repositories and versions are similar to kotlin-maven-plugin.
