is this due to the way

String::replace

works? if so, isn't this a bug, why is it removing my escape sequences?

you can use raw strings

""" """

which don’t use escape characters to make sure you’re not accidentally missing a backslash or something somewhere

yes using raw string works

sorry, I wanted to give you a pragmatic answer first 😅

@gildor like this? https://plugins.gradle.org/plugin/com.heroku.sdk.heroku-gradle/1.0.1 /cc @cedric

allows for

./gradlew build deployHeroku

@codefinger Nice find. Doc is sparse though

Searching by tags reveals another interesting plug-in: https://plugins.gradle.org/search?term=heroku

@cedric there's https://github.com/heroku/heroku-gradle#configuration. i think there's not much more too it. but yea, I could have better docs

Migrating from old authentication method to new one in apis... @orangy. Would want to release an app client with new one, but want to keep the old one until everyone upgrades

I am getting NoClassDefFoundError: kotlin/jvm/internal/Intrinsics while attempting to run Kotlin written servlet. Did anyone get this type of error?

I have published my demo app Kotlin + DropWizard + Heroku: https://github.com/cbeust/koolaid Thanks @codefinger for his help with Heroku deployment. /cc @fred.deschenes @orangy @dave @m Also might be relevant to you, @George

Similar to what is being discused, Kafka Streaming SQL https://www.confluent.io/product/ksql/

https://azure.microsoft.com/en-us/blog/public-preview-of-java-on-app-service-built-in-support-for-tomcat-and-openjdk/ Anyone using Azure? How’s it?

@orangy (cross post from another slack):

There’s pockets where you can see that somebody sensible has been involved. But it’s not enough to offset the business as usual shit show elsewhere.

I am most angry with their product management. There’s all these clever features that have been built while core functionality still doesn’t work. Of course the clever features also don’t work. Azure automation is a case in point: there’s online test and authoring tools that can’t possibly produce a sensible development process. But basic dependency management and environment isolation doesn’t exit. And resource scheduling is clearly broken somehow.

Still glad I gave it a proper chance. Relieved to be able to kill it quickly.

(that's not my opinion btw - I've not used Azure - but that of someone who's opinion I hold very highly)

nice to see Azure hasn't changed a bit in the 3 years I haven't touched it then

I'm using Azure quite extensively these days. Lots of things suck. My biggest pet peeve is naming things -- namespaces are a mix of your own account, region, and global, AND its nigh impossible to change names once they are created, so the end result is a completely inconsistently named set of resource and services, even if you start out with good intentions. I also agree about things like Azure Automation. Overall I would give it a B- grade. Usable, but not awesome.

Hello! We have multi-module project (js+common+backend). On the server side a Hot-Swap feature doesnt work at all. What could be the reason for this?

A while back (maybe a year ago?), there was a comparison of Kotlin server frameworks or a repo w/ sample code in multiple frameworks...does anyone still have a link to this? Slack's 3 month backscroll limit is pretty annoying 😞

@kenkyee can't help you with the past on this channel, but at least a few of the stacks have an implementation on https://www.todobackend.com/ . You could also look at the tech-empower benchmark repo, although the solutions aren't really very "domainy" IMHO 🙂

@kenkyee well if you find it then let us know which one it is then we can do an #http4k example 🙂 . I would suggest it's https://realworld.io/ but that doesn't have too many (one!) Kotlin examples. techempower does have database access, but no login btw.

Close to what I'm thinking but just the REST API portion...that looks like a comparison of all the frontend frameworks as well, but definitely is more realistic than the todobackend and techempower stuff which are almost trivial 🙂

Do you mean my very primitive benchmarks? https://github.com/orangy/http-benchmarks Or more sophisticated techempower.com/benchmarks/ ?

I think I might have been thinking your primitive benchmark but thought it was more complicated 🙂 Basically looking to set up a realistic "typical" REST API...something that supports session token refreshes (for Oauth), login, secured API endpoints, CORS, JWT. Not sure what kind of simple app to do for this yet, but maybe a shopping cart. I'm surprised Grizzly is so slow too..uses NIO so it should be pretty fast.

Does anyone has experience with using Kotlin with Mapstruct? I have applied kotlin-kapt and kotlin-jpa plugins. But it is still saying my entity class(data class) does not have an accessible empty constructor. Since “kotlin-jpa is a wrapped on top of no-arg”, I was assuming that this should work automatically, am I missing anything? I have also tried adding the kotlin-allopen plugin and setup the annotation, but there is still no luck. Any suggestion will be appreciated, thanks!

neat test @orangy, thanks

Hello, my kotlin application (built with ktor and run with netty) works perfectly by

./gradlew run

. But when I run

./gradlew build

and try to start unpacked distr, I receive

Caused by: java.lang.LinkageError: loader constraint violation: when resolving method "kotlin.sequences.SequencesKt.map(Lkotlin/sequences/Sequence;Lkotlin/jvm/functions/Function1;)Lkotlin/sequences/Sequence;" the class loader (instance of io/ktor/server/engine/OverridingClassLoader$ChildURLClassLoader) of the current class, org/jetbrains/squash/drivers/JDBCDatabaseSchema, and the class loader (instance of sun/misc/Launcher$AppClassLoader) for the method's defining class, kotlin/sequences/SequencesKt___SequencesKt, have different Class objects for the type kotlin/jvm/functions/Function1 used in the signature

As you can see, I use H2 database as squash as ORM. Have you ever seen this error? Where I may be wrong?

(Ubuntu, Oracle JDK 8, Kotlin 1.2.30, distr is built on this machine)

Is there any magic mojo I can add to my gradle.build to fix this when building with java 9:

Symbol is declared in module 'java.base' which does not export package 'sun.security.util'
