QUESTION
I am trying to publish my Kotlin multiplatform library to Maven Central via Sonatype. This repository requires me to include a javadoc.jar
file with my artifacts. Unfortunately, the IntelliJ IDEA project wizard and the Kotlin multiplatform docs do not help me do that. When running the Gradle task dokkaJavadoc
(for the official Kotlin documentation tool Dokka), I get the error "Dokka Javadoc plugin currently does not support generating documentation for multiplatform project."
I actually do not need genuine JavaDocs for publishing - an empty javadoc.jar
or one with other docs generated by Dokka would suffice. Since I have been a longtime Maven user and these are my first steps with Gradle, I have no idea how to do that.

Answered 2021-Mar-19 at 20:10This answer is a cross-post from Kotlin Discussions. Credit goes to Lamba92_v2 of the JetBrains Team, who linked his solution in his project kotlingram.
I noticed I had another issue related to publishing: Signatures and POM information where not applied to all modules. But given Lamba92_v2's code I could resolve all publishing-related issues:
QUESTION
I'm toying around with a small ktor webapp where I want to split functionality in multiple modules. I have a root module where I install the features I want to use throughout the whole application
...ANSWER
Answered 2021-Mar-18 at 07:55Yes, this is a proper way to test an application because modules don't depend on each other and are bound via configuration. Also, instead of adding one more extension method for Application
, you can introduce the following helper function just for testing:
QUESTION
I have been trying to setup kotest in a kotlin multiplatform project.
On the kotest starting guide it says to add this dependency to commonTest
ANSWER
Answered 2021-Feb-25 at 22:53It appears that kotest does not yet support the Kotlin compiler's IR backend for JS. This is kotest issue 2037. If you configure the LEGACY compiler backend for your JS multiplatform settings, it should work.
Kotest's Quick Start documentation does actually cover multiplatform configuration when you select the rightmost tab ("Multiplatform") in each section.
These are the relevant sections from a build.gradle.kts
script which uses kotest with the IR backend on JVM along with the LEGACY backend on JS:

QUESTION
I looks like there's no native module with io.kotest.core.spec.style.FreeSpec
, or am I missing something?
ANSWER
Answered 2020-Dec-10 at 08:41According to this build.gradle.kts from the Kotest repo, the only available targets are JVM and JS. I also found an issue with some discussion about K/N support.
QUESTION
I have been reading through the LiveDatatestUtil.kt provided as part of the Android Architecture Components Samples, and I have been trying to work out how to test Events with it within Kotest, so far as possible. Mainly because (right now) Kotest doesn't provide LiveData testing capability. Is there an idiomatic way to test Events (based on LiveData), that is based on the published util?
...ANSWER
Answered 2020-Dec-05 at 07:20My solution is add the following to the util:

I am trying to set a global project configuration for Kotest. I have followed the instructions at https://kotest.io/project_config/

...ANSWER
Answered 2020-Nov-25 at 11:26So it seems that the kotest documentation is slightly misleading (I have filed an issue: https://github.com/kotest/kotest/issues/1866). I have found that the dependencies needed in my app-level build.gradle are of the form:
QUESTION
I'm getting started with unit tests in Kotlin using Kotest. I use the following technologies that integrate somehow with Kotest:
- Kotest itself
- Kotlin / JVM
- Gradle
- Allure
- Pitest
- IntelliJ IDEA Plugin "Kotest"
In gradle, I included the following dependencies:
io.kotest:kotest-runner-junit5:$kotest_version
: Kotest Frameworkio.kotest:kotest-assertions-core:$kotest_version
: Kotest Core JVM Assertionsio.kotest:kotest-property:$kotest_version
: Kotest Property Testio.kotest:kotest-extensions-allure:$kotest_version
: Data collection for Allureio.kotest:kotest-plugins-pitest:$kotest_version
: Plugin for Pitest
The problem is that now, when I run my tests via the gradle :test
task, I get the following exception:
java.lang.IllegalArgumentException: Received a failure event for test with unknown id '2.27'. Registered test ids: '[2.1, :test, 2.25]'
The unknown id / registered ids differ in every test run. Actually there are a lot of errors appearing, but that one is the last one to appear. Below is the full gradle output (shortened internal calls):
...ANSWER
Answered 2020-Nov-07 at 19:28Seems like I found a solution.
The problem seems to be that Kotest (and later down the stream also JUnit) wants unique tests, which means unique test names. And normally, those problems would be marked by the Kotest IntelliJ plugin. But if you use a test factory, things are a bit more opaque. I was assuming that include(prefix, testFactory)
adds the prefix
to the test name, but this is not the case. which means that the factory method
QUESTION
I am new to sequences, so I may have done something (more or less) terribly wrong, but I have a questiion:
I have written two functions:
...ANSWER
Answered 2020-Oct-18 at 13:41It is expected. The variant with sequence creates an Iterator
object, and calls .hasNext()
and .next()
functions for each element.
Since an Iterator
works with objects and not primitives, all your int
s are boxed via Integer::valueOf
calls. (Note: .map { it }
step is redundant).
I ran both functions via Java Flight Recorder in IntelliJ Idea, and we can see that the sequence variant causes many more function calls compared to the other variant.
isPrimeNumber1:
isPrimeNumber2:
As you can see, the isPrimeNumber2
variant causes many more functions to be called under the hood, and therefore is impacted by their overhead.
Another way of inspecting it is to decompile both functions' bytecode to Java. It can give you better insight on what is going on under the hood. Here's both of the functions decompiled (again using IntelliJ):
