I'm trying to port this to kotlin and merge it with my buildscript for last 3-4 hours and I'm completely stuck... https://github.com/PaleoCrafter/Dependency-Extraction-Example/blob/coremod-separation/build.gradle
j

jlleitschuh

10/11/2017, 6:05 PM
Hi Bartosz, Do you have an example of your attempted port that isn't working? Be aware that:
task coreJar(type: Jar) {
    //...
}
Is creating a task called
coreJar
, not pulling it from some task created by a plugin. The syntax to convert that to kotlin would be:
task<Jar>("coreJar") {
    // Your logic here.
}
b

barteks2x

10/11/2017, 6:07 PM
I tried exactly that syntax, and the ForgeGradle plugin game me that error. I also tried:
tasks {
    "coreJar"(Jar::class) {
          // logic here
    }
}
with the same result
j

jlleitschuh

10/11/2017, 6:08 PM
What error?
b

barteks2x

10/11/2017, 6:08 PM
* What went wrong:
A problem occurred configuring root project '1.12'.
> coreJar  is not a jar task. Can only reobf jars!
this is part of ForgeGradle trying to tell me something
j

jlleitschuh

10/11/2017, 6:11 PM
Can you link to your current code?
b

barteks2x

10/11/2017, 6:11 PM
it comes from the equivalent of this:
reobf {
    coreJar { mappingType = 'SEARGE' }
}
which is
configure<NamedDomainObjectContainer<ReobfTaskFactory.ReobfTaskWrapper>> {
    create("coreJar").apply {
        mappingType = ReobfMappingType.SEARGE
    }
}
my current code: https://hastebin.com/sicemaruna.scala (this is with addition to my project)
j

jlleitschuh

10/11/2017, 6:13 PM
You're sure that:
configure<NamedDomainObjectContainer<ReobfTaskFactory.ReobfTaskWrapper>>
is equivalent??
b

barteks2x

10/11/2017, 6:15 PM
yes, I'm sure
j

jlleitschuh

10/11/2017, 6:15 PM
So in full, you have something like this?
task coreJar(type: Jar) {
    //...
}

configure<NamedDomainObjectContainer<ReobfTaskFactory.ReobfTaskWrapper>> {
    create("coreJar").apply {
        mappingType = ReobfMappingType.SEARGE
    }
}
b

barteks2x

10/11/2017, 6:15 PM
well, I have
tasks {
    "coreJar"(Jar::class) {
          // logic here
    }
}
which I saw in samples
but basically, yes
j

jlleitschuh

10/11/2017, 6:16 PM
Try putting:
configure<NamedDomainObjectContainer<ReobfTaskFactory.ReobfTaskWrapper>> {
    create("coreJar").apply {
        mappingType = ReobfMappingType.SEARGE
    }
}
Into an
afterEvaluate
block and see what happens
b

barteks2x

10/11/2017, 6:18 PM
well, I actually have 2 of create("something").apply { blocks, I just realized that it could be bug in that plugin that makes it break when 2+ are there
it seems to work with afterEvaluate
but Ihave no idea why it's needed when it works without kotlin dsl
j

jlleitschuh

10/11/2017, 6:20 PM
I agree that it's strange. I'm going to guess that there's an execution ordering problem.
b

barteks2x

10/11/2017, 6:21 PM
Considering the strange things the FG plugin does, it's not that unlikely
well, now I actually get this
* What went wrong:
Execution failed for task ':reobfCoreJar'.
> org.gradle.jvm.tasks.Jar_Decorated cannot be cast to org.gradle.api.tasks.bundling.Jar
and the previous error is straneg too because that part that does
throw new GradleConfigurationException(jarName + "  is not a jar task. Can only reobf jars!");
is in afterEvaluate in that plugin's code
j

jlleitschuh

10/11/2017, 6:28 PM
So, Gradle weirdness, there are actually two
Jar
tasks. One is just an interface for the other one.
b

barteks2x

10/11/2017, 6:29 PM
is it just a change in gradle internals in some version that broke the plugin?
OH
default imports broke it
j

jlleitschuh

10/11/2017, 6:33 PM
Yea, that.
Because the default
Jar
is probably different than the one the plugin expects.
b

barteks2x

10/11/2017, 6:34 PM
Should I report it as an issue that the
org.gradle.api.tasks.bundling.Jar
needs fully qualified name to be used?
it's impossible to use without using fully qualified name
j

jlleitschuh

10/11/2017, 6:34 PM
Yea, I think the forge gradle plugin needs to be updated.
b

barteks2x

10/11/2017, 6:34 PM
to use the other jar task?
j

jlleitschuh

10/11/2017, 6:35 PM
Yea,
b

barteks2x

10/11/2017, 6:35 PM
Good luck with getting ANY change into ForgeGradle...
also to me it looks like
org.gradle.api.tasks.bundling.Jar
is actually in the API. Shouldn't that one be actually imported by default?
j

jlleitschuh

10/11/2017, 6:41 PM
@bamboo or @eskatos Can you explain the weird
Jar
api, why there are two of them, ect... to me again because I still don't really understand. I know it has something to do with not breaking the API.
b

barteks2x

10/11/2017, 6:42 PM
and yet it turned out to be a breaking change
j

jlleitschuh

10/11/2017, 6:42 PM
True, it probably changed during a major version bump. ¯\_(ツ)_/¯
b

barteks2x

10/11/2017, 6:44 PM
wekk, breaking change when used together with kotlin's default imports
j

jlleitschuh

10/11/2017, 6:45 PM
I mean, these are the same default imports used by Groovy too.
b

barteks2x

10/11/2017, 6:48 PM
I would be able to debug it if I could add breakpoints in gradle code...
j

jlleitschuh

10/11/2017, 6:48 PM
Supposedly you can, but I haven't ever been able to get it to work.
b

barteks2x

10/11/2017, 6:48 PM
You can add them but they don't work
It's also unlikely it can be fixed in FG because it probably still builds against gradle 2.x
j

jlleitschuh

10/11/2017, 7:02 PM
Well that's their problem. That's really old, they should update their build.
b

barteks2x

10/11/2017, 7:10 PM
its not their problem if they don't claim compatibility with gradle 4.x
j

jlleitschuh

10/11/2017, 7:11 PM
¯\_(ツ)_/¯
b

barteks2x

10/11/2017, 7:13 PM
anyway, now I can try to make publishing to maven work
e

eskatos

10/12/2017, 6:34 AM
Like Jonathan said, Kotlin DSL default imports are the very same as the ones you get in the Groovy DSL. But thanks to the Groovy magic it may work anyway, but Kotlin doing strict type checking forces you to use a fqcn here. Agreed that FG should update their build, or you have to live with the fqcn.
After taking a closer look, that’s on Gradle & Kotlin DSL. The Groovy DSL actually imports the “old”
Jar
task by default. This will be fixed in the upcoming Gradle 4.3.
