kotlinlang #build-tools

the 1.2.2x releases seem pretty broken. Lot of colleagues reporting just weird issues popping up - Kotlin plugin in gradle fails to apply - breakpoints won’t hit in tests -

Cannot access 'XXX': it is internal in 'YYY'

happening in random places (cleared by a gradle clean or killing daemons) all on android studio, but haven’t tested intelliJ

That’s fair. But the message from IDE is confusing: Test events were not received. I know this may because gradle won’t trigger the test event when nothing changes. But still, a little bit confuse 😄

How to enable new compiler option

I am generating some Kotlin code using KotlinPoet. How would I best mark the target directory as a code-source using Gradle? The following works, but marks the directory as a regular source root in IntelliJ, instead of "Generated Sources Root"

Copy code

sourceSets {
    main.kotlin.srcDirs += 'generated/kotlin'
}

I do not want to have to explicilty disable a company made lint rule in my personal project, but I’m not sure how. I cannot see where this company specific lint rule is living. Seems like it’s living within Android Studio iteself

Hi all! Does anyone know if it’s possible for the

-Werror

flag to ignore generated files? I assume not, but just wanted to ask

We are glad to announce beta version 0.2.0 of Gradle inspection plugin! Gradle inspection plugin is a tool which is able to run Kotlin inspections, code reformatting and cleanup as Gradle tasks, using configurable versions of IDEA CE and Kotlin plugin. The tool can be helpful as a part of continuous integration and/or code review tools and/or code analysis tools. It's still "project under development", but we will greatly appreciate any feedback about the tool. Basic usage information can be found in README here: https://github.com/JetBrains/inspection-plugin.

hey, @Alexander Podkhalyuzin [JB], at KotlinConf we've talked about the possibility of having code hot reload in Gradle builds. You've asked me to remind you 😉

Is there any good reason to use Gradle when you are used to Maven?

I'm build a kotlin library and when I run build with

./gradlew build

, it creates the jar file, but not when I use

Build Project

Build Module

in Intellij. How do I get those commands to have the same output?

Does anyone know of any good procedure or build tool to help you with semantic versioning when you are creating libraries? For example, I would need something that make sure I do not accidentally change a function or class that is exposed in the API of my library in a breaking way. So I would get an warning or error at build time if the signature of a function has changed.

Hi, I'm wondering if there are any best-practises or points to think about when deciding how much or when to modularize a project into multiple build files (maven modules, gradle subprojects). Does anyone have any good advice for when, and how to decide what to break up into different build modules?

In maven and gradle you can set

<kotlin.code.style>official</kotlin.code.style>

for a code style (which is super nice). Is there tooling which can lint the code to follow the code style? Would be great to have it directly in maven, but a additional tool would also be fine

Hi everyone, I have issues creating a library fat jar for my kotlin project. I’m using the built-in jar plugin and adding the compiled dependencies. This is the task:

Copy code

task fatJar(type: Jar) {
    from {
        // Add runtime dependencies to jar.
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
    with jar
}

Is there something wrong? When I include the jar into another project I can only see my classes from the Java code, not the Kotlin one.

Hey, I have a weird one. I have a project that is currently building fine on a colleagues windows pc, it also builds fine on our TeamCity agent. However, on my pc Windows 1809, I get the following exception (will post below). I've tried

mvn package

on wsl (ubuntu 1804) using the default jdk (10) as well as openjdk11 both give the same error. Same error when I try and run from intellij (right click green arrow -> run ). Any ideas 😕

I realized that #gradle might not be the right channel for this question, because it’s about the Kotlin DSL. Is there a way to do this?

Hi! I have a question about kotlin-maven-plugin. Do I have to provide configuration parameters explicitly like in example below:

Copy code

<plugin>
	<groupId>org.jetbrains.kotlin</groupId>
	<artifactId>kotlin-maven-plugin</artifactId>
	<version>${kotlin.version}</version>
	<executions>
		<execution>
			<id>compile</id>
			<phase>compile</phase>
			<goals>
				<goal>compile</goal>
			</goals>
		</execution>
		<execution>
			<id>test-compile</id>
			<phase>test-compile</phase>
			<goals>
				<goal>test-compile</goal>
			</goals>
		</execution>
	</executions>
	<configuration>
		<jvmTarget>${java.version}</jvmTarget>
		<javaParameters>true</javaParameters>
	</configuration>
</plugin>

or I could simply set a property like this:

Copy code

<properties>
	<kotlin.compiler.jvmTarget>1.8</kotlin.compiler.jvmTarget>
</properties>

I'm trying to track down a problem with the kotlin bazel rules, which seems to occur when you switch from pulling in kotlinc 1.3.40+. The compiler seems to have no problems if it's <= 1.3.31, but anything past 1.3.40+, with no infrastructure/rules changes, results in failure to see internal types and methods. Repeat, it's precisely the same rule infrastructure, so it builds

-Xfriend-paths

and does all of that. The only variable is swapping in a later kotlinc. I can't find anything in the change-logs to indicate a change in internal/module enforcement in that timeline. Anyone know of changes that might affect internal enforcement and the behavior of

-Xfriend-paths
