play-scala-rest-api-example's Issues

Update documentation with fixed links to ECS

If you read http://dev.lightbend.com/guides/play-rest-api/ then the link https://example.lightbend.com/v1/download/play-rest-api is dead because the example was renamed:

https://github.com/playframework/play-scala-rest-api-example/tree/2.5.x/docs/src/main/paradox

move to Scala 2.12

currently build.sbt has:

// This must be set to 2.11.11 because Gatling does not run on 2.12.2
scalaVersion in ThisBuild := "2.11.11"

but according to @manohar9999, Gatling may actually work with 2.12? has it been tried recently? (regardless, we should at least have an open issue on this, so here one is)

I tried cloning the repo, changing scalaVersion to 2.12.2 and got:

[error] Modules were resolved with conflicting cross-version suffixes in {file:/Users/tisue/play-scala-rest-api-example/}root:
[error]    com.typesafe.akka:akka-actor _2.12, _2.11
[error]    org.scala-lang.modules:scala-xml _2.12, _2.11
[error]    org.scala-lang.modules:scala-java8-compat _2.12, _2.11
[error]    org.scala-lang.modules:scala-parser-combinators _2.12, _2.11
[error]    com.typesafe.akka:akka-slf4j _2.12, _2.11

it appears from gatling/gatling#3179 that there may be WIP on a 2.12-friendly build of Gatling, but may not a release yet? I'd dig deeper, but I thought I'd check first if y'all already know more about this than I do

this is of interest to the Scala team and the HPE Fortify integration effort, since all of the Play example repos are good QA fodder (as suggested by @wsargent)

Gatling load test failing on Ubuntu 16.04

Just cloned and tried running gatling test following steps provided on README,
local repository is exactly the same as version from origin/2.5.x

when running sbt gatling:test I get:

[error] Uncaught exception when running simulation.GatlingSpec: java.lang.NoSuchMethodError: org.asynchttpclient.netty.channel.DefaultChannelPool.<init>(IILio/netty/util/Timer;)V

OS: Linux Ubuntu 16.04
Java: 1.8.0_131

Forward port additional tests to 2.6.x branch

@guilhebl did a bunch of work to add tests -- should cherry-pick to 2.6.x branch before GA.

Error when running gatling test

After doing a clone and following through the readme everything works except gatling throws an error after running "sbt gatling:test"

All I could find online was this pastebin https://pastebin.com/byJechzK with the same problem but no solution.

Intellij + gradle = no scala sdk

I want to use the project with the gradle build. Unfortunately every time I reload the build.gradle file, Intellij forgets the path to the scala sdk. Thus no sources can be read, no color coding is made, ...

Here is the error I get in the console:

Warning root project 'play-scala-rest-api-example': Unable to build Scala project configuration
Details: org.gradle.api.GradleException: Cannot infer Scala class path because no Scala library Jar was found. Does root project 'play-scala-rest-api-example' declare dependency to scala-library? Searched classpath: file collection.

I have removed everything related to sbt.

Have you had problems like these when you added the gradle related code to the project?
Any ideas what could be done to overcome this?

Thanks

Readme typo

In the readme

bin/play-rest-api-example -Dplay.crypto.secret=testing

should be

./bin/play-scala-rest-api-example -Dplay.crypto.secret=testing

Use PlayService plugin

Use PlayService plugin to show how to create a more stripped down REST service.
