Ant
Defining <kotlinc> task using local Kotlin setup
One way to define Ant's <kotlinc> task is by using your local Kotlin setup and KOTLIN_HOME environment variable:
Alternatively, you can copy all jar files from Kotlin distribution to Ant's "lib" folder.
<kotlinc> attributes
| Name
|
Description
|
Required
|
Default Value
|
|---|---|---|---|
| src
|
Kotlin source file or directory to compile | "src" or "module" needs to be specified | |
| module
|
Kotlin module to compile | "src" or "module" needs to be specified | |
| output
|
Destination directory | If "src" is used - "output" or "jar" needs to be specified | |
| jar
|
Destination jar file | If "src" is used - "output" or "jar" needs to be specified If "module" is used - only "jar" can be specified or it can be omitted |
"moduleName.jar"
|
| classpath
|
Compilation class path | false
|
|
| classpathref
|
Compilation class path reference | false
|
|
| stdlib
|
Path to "kotlin-runtime.jar" | false
|
""
|
| includeRuntime
|
If "jar" is used - whether Kotlin runtime library is included | false
|
true
|
<kotlinc> accepts a nested <classpath> element, similarly to <javac>.

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:
| Milestone | Version |
|---|---|
| M1 | 0.1.2090 |
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):
