WebJarAssets cannot locate jQuery.min.js

My setup used org.webjars.webjars-play.2.5.0 with Scala Play 2.5. I was using couple of WebJars libraries for different purposes and ended with 2 jquery.min.js files located in 2 directories, target/web/web-modules/main/webjars/lib/jquery and target/web/web-modules/main/webjars/lib/jquery/dist.

When I accessed the index web page, an exception [IllegalArgumentException: jquery/jquery.min.js could not be found was thrown by <script type="text/javascript" src="@routes.WebJarAssets.at(webJarAssets.locate("jquery/jquery.min.js"))"></script> even though the file existed at target/web/web-modules/main/webjars/lib/jquery/jquery.min.js. I tried different path lib/jquery/jquery.min.js to locate the script but unsuccessful. However, when dist/jquery.min.js is used, it can find the script but it is the version I wanted.

How do I configure to help WebJarAssests to locate the jquery.min.js in target/web/web-modules/main/webjars/lib/jquery? How do I stop other WebJars from loading a different versions of jquery.min.js into my project? Thanks

Meanwhile, I am using <script type="text/javascript" src="@routes.Assets.at("lib/jquery/jquery.min.js")"></script> to get things going.

Current setup,

class ApplicationController @Inject() (
  val webJarAssets: WebJarAssets,
  val silhouette: Silhouette[CookieAuthenticatorEnv],
  ...
) extends AuthController {...}

@(webJarAssets: WebJarAssets, ...)(implicit messages: Messages)

GET         /webjars/*file          controllers.WebJarAssets.at(file)
Solution

  • You can either use the regular Play Static Asset stuff + sbt-web to use the target/web/web-modules/main/webjars/lib files, or you can use the WebJarAssets thing. More details in the docs.

    To use WebJarAssets, instead of:
    webJarAssets.locate("jquery.min.js")

    Try:
    webJarAssets.locate("jquery", "jquery.min.js")
