If I have a set of targets defined from presets what is the command line invocation to just build/test one of the targets?

targets {
        fromPreset(presets.iosX64, 'ios') {
            compilations.main.outputKinds('FRAMEWORK')
        }
        fromPreset(presets.android, 'android')
        fromPreset(presets.jvm, 'jvm')
    }

To build and test, you may use the following task:

<targetName>Test

, read more about it here: http://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#running-tests. For just a build, use

<targetName>Jar

or, for native targets,

compileKotlin<targetName>

to build a

klib

and

linkDebug<outputKind><targetName>

or

linkRelease<outputKind><targetName>

to create an executable file, framework, *.so, etc. — for example,

linkDebugFrameworkIos

,

linkDebugExecutableMac

. There is no straightforward analog for

build

and

assemble

tasks which is suitable for a specific target, but you may follow the request to get the future updates on the question: https://youtrack.jetbrains.com/issue/KT-27443
