Scala play - "not found: value routes" (Eclipse and IDEA)

Question

Occasionally, and seemingly for no reason, I get "not found: value routes" compilation error in one of the view templates (after compilation). This happens either in Eclipse or IDEA.

Googling finds this but it's not possible to add mainLang = SCALA in play 2.10 (I'm using version 2.1.2).

Cleaning the project / re-eclipsifying it / seems to work, sometimes, but is there any more permenant solution / work-around?

Thanks

Answer 1

sbt compile

Then IntelliJ loads the output of the compilation and everything just works for me.

Answer 2

This can happen if the routes file does not exist or contains no routes.

Answer 3

Since there seems to be no answer, I'll at-least describe my workaround: Instead of using

<link [email protected]("stylesheets/style.css") rel="stylesheet" type="text/css" />

in my template HTML, I'm using

<link href="assets/stylesheets/styles.css") rel="stylesheet" type="text/css" />

Since I'm not invoking routes.Assets.at, there is no issue with not finding the value routes. (However, I'm guessing this workaround will easily crumble when I would have need of more complex templates)

Answer 4

I have this working defining an Asset Controller

object Assets extends controllers.AssetsBuilder

and having the route for assets too in the routes conf:

\#Map static resources from the /public folder to the /assets URL path
GET     /assets/*file          premise.internet_org.controllers.Assets.at(path="/public", file)
