Also, why are you overriding

sourceSets

-- do you have a non-standard directory layout?

Has anyone ever used AspectJ with Kotlin? I can’t get it to work with a Kotlin using either the compiler or the load-time weaver. I’m trying to add some cross-cutting concerns and I really like aspects for that.

Yea,

I found that, but I was wondering if anyone actually got it working

Enabling kapt doesn’t work with a pure kotlin application

Sorry, I mean enabling kapt doesn’t help with a pure kotlin app when you’re trying to use AspectJ

sorry, i didn’t try anything of the sort

@Devon Humes I am not surprised it won't work for compile-time weaving. How are you building your code? Gradle, Maven, something else?

@Rafael Chaves I’m using Maven.

maybe you should give gradle a try then

@Devon Humes You caught my curiosity (big fan of AspectJ - back in the day - and Maven, and of course, Kotlin) - it didn't work for me at first, after a bit of of investigation, it seems it was a matter of configuring the aspectj compiler plugin correcly. See: https://github.com/abstratt/sandbox/tree/master/kotlin-aspectj-example

@Rafael Chaves Thanks! That looks great! How did you make it work without kapt?

Is it because we only care about them at compile time and they are marked as runtime dependencies? We really aren’t doing any annotation processors.

To be honest, I just assumed it would work as it does with Java, since Kotlin is supposed to work well with Java-oriented frameworks/tools

Of course, keeping in mind that Java tools that work at the source level will not work with Kotlin source code

But once it is compiled...

Any of you have experience deploying a Kotlin app in the cloud? Kubernetes? Heroku? Other?

heroku

Seems to be the most turnkey solution so far

heroku is easy, but otherwise if you have 12factor app any cloud will work

Hadn’t heard that term

12factor

but yeah I’m not interested in getting tied to a proprietary cloud (e.g. Google Cloud Engine with its own endpoints and persistence)

Google Cloud is another option (https://cloudplatform.googleblog.com/2017/06/Google-App-Engine-standard-now-supports-Java-8.html), but it is proprietary as Cedric has mentioned.

@cedric if you follow the instructions here, you can create an entire github->travis->heroku CD pipeline containing a kotlin /jetty app (of course http4k! 😀) in one line of bash. http://start.http4k.org

(you need a couple of API keys and accounts but all the detail is in the doc)

Interesting, thanks @dave

@cedric on a more general answer to your question - yes, it's easy. As was pointed out, designing to the 12 factor principles makes things portable for any PaaS solution. K8S will probably have helm charts available to create java service clusters with auto scaling if you want to go down that route.

But you will end up with the management cost with k8s and if you just want a running webapp a PaaS (or equivalent) is less hassle
