Hi -

Migrating from 2.5 to 2.6, I have run a across a problem where Guice is unable to wire up my application.

ProvisionException: Unable to provision, see the following errors:

1) Error injecting constructor, java.lang.NoSuchMethodError: controllers.AssetsBuilder.<init>(Lplay/api/http/HttpErrorHandler;)V
  at controllers.WebJarAssets.<init>(WebJarAssets.scala:19)
  at controllers.WebJarAssets.class(WebJarAssets.scala:19)
  while locating controllers.WebJarAssets
    for the 4th parameter of controllers.SignOutController.<init>(SignOutController.scala:21)
  while locating controllers.SignOutController
    for the 16th parameter of ....

This is a very thorough error message, and I feel like what I need to do should be obvious, and yet I'm stymied.

The code worked in 2.5.  I updated relevant portion of build.sbt to 

"com.typesafe.play" %% "play-json" % "2.6.2",
"org.webjars" %% "webjars-play" % "2.6.0",

I am not a Play expert and decidedly not a Guice expetrt.  It looks like some constructor signature changed from 2.5 to 2.6, and Guice can't wire the app together, 
but I'm damned if I can't figure out what and where to fix it.

Any pointers would be appreciated.

Thanks

Hi Jim,

It looks like a binary compatibility issue (as generally NoSuchMethodError is). It's trying to call the AssetsBuilder(HttpErrorHandler) constructor, but in Play 2.6 that constructor instead takes two arguments, HttpErrorHandler and AssetsMetadata. It looks like WebJarAssets in webjars-play has been updated to support it (https://github.com/webjars/webjars-play/blob/master/src/main/scala/org/webjars/play/WebJarAssets.scala#L12) but for some reason you're probably compiling against the older version written for Play 2.5.

Maybe you can try cleaning your project and trying to build again? You can also try upgrading to webjars-play 2.6.1 and see if it makes a difference.

Hello Greg,

I'm having the same issue. Here's what I'm using:

build.sbt:
"org.webjars" %% "webjars-play" % "2.6.1",

plugins.sbt:
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.6.2")

HomeController.scala:
class HomeController @Inject() (
    webJarAssets: WebJarAssets,
    requireJS: RequireJS,
    components: ControllerComponents)
  extends AbstractController(components) {

  def index = Action {
    Ok(views.html.index(webJarAssets, requireJS))
  }

}

views/index.scala.html:
@(webJarAssets: WebJarAssets, requireJS: org.webjars.play.RequireJS)

<!DOCTYPE html>
<html>
    <head>
        <script type='text/javascript' src='@routes.WebJarAssets.at(webJarAssets.fullPath("react", "react.js"))'></script>
        <link rel='stylesheet' href='@routes.WebJarAssets.at(webJarAssets.locate("css/bootstrap.min.css"))'>
        <link rel='stylesheet' href='@routes.WebJarAssets.at(webJarAssets.locate("css/font-awesome.min.css"))'>
    </head>
    <body>
        <div id="app"></div>
        <script type='text/javascript' src='@routes.Assets.versioned("javascripts/bundle.js")'></script>
    </body>
</html>

routes:
# An example controller showing a sample home page
GET     /                           home.HomeController.index

# Map static resources from the /public folder to the /assets URL path
# GET     /assets/*file               controllers.Assets.versioned(path="/public", file: Asset)
GET     /assets/*file               controllers.Assets.at(file)
GET     /versionedAssets/*file      controllers.Assets.versioned(file)
GET     /webjars/*file              controllers.WebJarAssets.at(file)

application.conf:

play.assets {
  path = "/public"
  urlPrefix = "/assets"
}

Yet, when I load localhost:9000 in my browser, I get the following error (see below). Could you offer any advice? Thanks.

Seems like a compatibility issue with webjars-play. You might want to report an issue there.

Thanks Greg,

In build.sbt, I changed

"org.webjars" %% "webjars-play" % "2.6.1",

to

"org.webjars" %% "webjars-play" % "2.6.0-M1",

and this has fixed the error.

Cheers,

Using 

"org.webjars" %% "webjars-play" % "2.6.0-M1"

I was able to get 2.6.1 working eventually by making sure my routes matched the documentation: http://www.webjars.org/documentation
