Building Ktor From Source

Ktor is an OpenSource project hosted at GitHub:<https://github.com/ktorio/ktor>

Release versions are available at both jcenter and maven central.

We usually provide binary version previews at bintray:<https://bintray.com/kotlin/ktor/ktor>

Additionally, you can use jitpack to get bleeding edge artifacts compiled from master:<https://jitpack.io/#ktorio/ktor>

Downloading the source

You can get the latest version of Ktor using git to clone Ktor’s repository:

1. git clone https://github.com/ktorio/ktor.git
2. cd ktor

Building

Ktor uses gradle for building. It should work with any gradle versiongreater than 4.3, but for best results we provide a gradle wrapper,which should work with any supported system with a JDK installed:

1. ./gradlew build

Installing locally

Ktor provides a gradle install task that installs Ktor artifacts in yourlocal maven repository:

1. ./gradlew publishToMavenLocal

Troubleshooting

If you get an error similar to:

1. * Where:
2. Build file '/.../ktor/ktor-server/ktor-server-benchmarks/build.gradle' line: 2

4. * What went wrong:
5. An exception occurred applying plugin request [id: 'me.champeau.gradle.jmh', version: '0.4.4']
6. > Failed to apply plugin [id 'me.champeau.gradle.jmh']
7. > Could not generate a proxy class for class me.champeau.gradle.JMHPluginExtension.

You might have forgotten to use the gradle wrapper (./gradlew), or your default installedgradle version is lower than 4.3.

Always use the gradle wrapper for consistent results!
