I recently switched from old 1.2 multiplatform into 1.3. Difference is, there's one one build.gradle file per multiplatform module (I got 5 of them) so a lot less configuration. However I can't seem to be able to configure creating runnable fat jar with all dependencies from jvm platform. I used to use standard "application" plugin in my jvm project and jar task, but that does not work anymore. I found there's "jvmJar" task and I modified it (set Main-class), but created jar doesn't contain dependencies and crashes on ClassNotFoundException. How do I do it?
This is what I have now:
jvm() {
jvmJar {
manifest {
attributes 'Main-Class': 'eu.xx.Runner'
}
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}
}
I did hit that bump and used this work around.
Lets call your project Project
.
create another submodule say subA
, which will have the gradle notation Project:subA
now, subA
has your multiplatform code in it (It is the gradle project with apply :kotlin-multiplafrom) in its build.gradle
create another submodule which targets only jvm say subB
, which will have the gradle notation Project:subB
So, subB
will have plugins: 'application'
and 'org.jetbrains.kotlin.jvm'
plugins {
id 'org.jetbrains.kotlin.jvm' version '1.3.31'
id "application"
}
apply plugin: "kotlinx-serialization"
group 'tz.or.self'
version '0.0.0'
mainClassName = "com.example.MainKt"
sourceCompatibility = 1.8
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
dependencies {
implementation project(':subA')
}
you can proceed and build subB as you would a regular java project or even use the existing plugins, it will work
