Any hints how to properly configurate shadow plugin? Getting these errors and since I have very limited experience with gradle and shadow plugin it’s not clear wha’t wrong (except for that some things are obviously missing) https://gist.github.com/jcechace/96e8dd2801b677a50a87cebb42e81748

[Nikky]

can you share your gradle file ? its possible you may be forced to use `compile`/`api` instead of implementation on some things - but thats just a random guess

[jcechace]

using compile on most of the things. https://gist.github.com/jcechace/6c1084defc5f15b67445b4fe44e4333c

[jcechace]

ok, on all the things

[Nikky]

first thing:

base {
    archivesBaseName = "app"
}

second: shadowJar does not like being applied before setting the mainclassname (at least when i am using it)
you can get around that with id("shadojar etc" version "2.0.4" )apply false

[Nikky]

i configure it like this:

plugins {
    ...
    id("com.github.johnrengelman.shadow") version "4.0.0" apply false
}
apply<ApplicationPlugin>()

                configure<JavaApplication> {
                    mainClassName = "package.MainKt"
                }

                apply(plugin = "com.github.johnrengelman.shadow")

                val runDir = rootProject.file("run")

                val run by tasks.getting(JavaExec::class) {
                    workingDir = runDir
                }

                val runShadow by tasks.getting(JavaExec::class) {
                    workingDir = runDir
                }

                val shadowJar by tasks.getting(ShadowJar::class) {
                    classifier = ""
                    archiveName = "${project.name.toLowerCase()}-${Env.versionSuffix}.$extension"
                }

                val build by tasks.getting(Task::class) {
                    dependsOn(shadowJar)
                }

[Nikky]

i am not sure if the Java Application stuff is stil necessary, at least for a while it did not like using the generated accesors

[Nikky]

i vopied it out of a much more complex usecase where i set up runnable subprojects based on a Map<Project, String>

[jcechace]

it shoudlnt/

[jcechace]

application {
    mainClassName = "io.apiman.watcher.WatcherAppKt"
}

should do the same

[jcechace]

also is there something else going on beside configuring the runDir to the one where “run” file is located”

[jcechace]

val runDir = rootProject.file("run")

[Nikky]

i use it in a few more places

[Nikky]

like adding it to idea ignore folder

[Nikky]

so you can inline it

[jcechace]

Hmm fails with

gradle assembleShadowDist --warning-mode all
The AbstractFileCollection.getBuildDependencies() method has been deprecated. This is scheduled to be removed in Gradle 5.0. com.github.jengelman.gradle.plugins.shadow.internal.DependencyFileCollection extends AbstractFileCollection. Do not extend AbstractFileCollection. Use Project.files() instead.

Turn out, only apply(plugin = "com.github.johnrengelman.shadow") was needed. Thanks @Nikky
