I have a kotlin project that is compiled to java.
My test library is junit.
Im using maven as my dependency management and Intellij IDEA.
recently I got that strange warning in my pom.
Inspection info: If you have kotlin-test and junit dependency then
most likely you better to include kotlin-test-junit instead of just
kotlin-test
What is the difference between kotlin-test and kotlin-test-junit?
from what I read it seems that kotlin-test is not deprecated, so Why did intellij recommend kotlin-test-junit instead of kotlin-test?
So I found the answer here (I don't understand how I missed it in my first search)
In short kotlin-test library provides a set of annotations and utility functions independently of the test framework.
Where kotlin-test-junit library provides an implementation on top of Junit Asserter and the annotations and utility functions kotlin-test provides.

i understand that i can use Kotlin Plugin comes with IntelliJ but i can also install Kotlin standalone compiler. Is there any pros/cons using standalone vs IntelliJ own integrated?
I'd say that:
Any real Kotlin project (including projects in IntelliJ) should use a build system such as Gradle or Maven.
Enabling Kotlin support in a Gradle/Maven project will automatically download the correct compiler (and switch it when you update the Kotlin version in the config file) and not care about whether you have a stand-alone version installed.
Any other Kotlin tool will likely be integrated with them as well.
So the standalone compiler is pretty much only useful when you want to try something quickly outside any project, but then https://play.kotlinlang.org/ or https://try.kotlinlang.org/ can work as well; and again let you switch between Kotlin versions simpler than a manually installed compiler.
Running Kotlin scripts may be the only case where I would use the stand-alone compiler.
Not much, but having own install have few advantages, but probably not needed by most people on their machines:
You don't need intellij, so you can use that compiler in other IDE or just for other applications
You can use different version of compiler than the one from plugin.
But in most cases integrated one is all you need.
If I wanted to build a website which used Kotlin both on the back-end, and in the browser - how would I set this up? Is there a Maven archetype or a Gradle template that captures best-practices for something like this?
The easiest way is to keep the modules separate, and I guess conceptually you'd probably want to do that also. While IntelliJ IDEA for instance doesn't natively support the ability to output to JS and JVM with Kotlin, in principle with Gradle/Maven you could. Here are instructions on targeting JVM and JavaScript for Gradle http://kotlinlang.org/docs/reference/using-gradle.html
I'm starting development using OSGi but when one of my concerns is about the lack of support at development time, meaning that commonly IDEs (started using Intellij IDEA) don't use OSGi for class discovery but classpath search IDE managed (I'm in search for one that uses OSGi instead).
The main concern here is to prevent classpath issues at execution time by suing the same OSGi mechanisms at development time.
Does any IDE work this way ?
update: added link to blog post with my experience with IDEA
OSGi is a runtime technology, therefore there is no such thing as an OSGi mechanism at build time. Also bear in mind that ultimately all Java code must be compiled by a Java compiler, usually javac. The javac compiler does not use package dependencies like Import-Package, it always uses JARs or directories on the classpath.
Having said that, Bndtools uses package filtering at build time, based on the exported and private packages of the dependencies. This is a special feature of Eclipse and it does not work when you compile outside of the IDE, e.g. with Ant or Maven. However it may still be useful because if you try to use a non-exported package from another bundle you will get a problem marker with a red X in the Eclipse IDE.
I'm trying to make Maven2 to compile coffeescript to javascript. As far as I'm concerned there is no plugin which provides compiling coffeescript.
Is there a compiler-plugin for maven which can be parameterized with a compiler (for any programming language)?
Is there a compiler-plugin for maven which can be parameterized with a compiler (for any programming language)?
This is actually the case of the Maven Compiler Plugin, see Using Non-Javac Compilers. So one could imagine providing a pluggable compiler implementation to compile coffeescript.

I need a build tool for compiling,testing, reporting and the deployment of Lua programs.
I chose Maven 2 because of our Polarion version supports it.
Unfortunately, I couldn't find any Maven plugins/archetypes for Lua.
As I am a newbie in Maven I want to know whether it is difficult to write a customized Lua plugin for Maven.
You can hook up the maven-compiler-plugin with any plexus compiler (reference here).
So I guess the standard way would be to write a plexus wrapper for the lua compiler using the Plexus Compiler API
