Play app with dependencies on 3 other play apps

问题

I am running a play app, this app has dependencies on 3 other play apps, i.e. the first play app has 3 dependencies in build.sbt.

Now of course all these 4 apps have their own route.conf file.

The thing is when I start the first app, APIs for one of the jars start working instead of the app that i started. What I mean is that all the API urls for the first app is invalid and doesn't open while APIs of one of the jars that I added as a dependency starts working.

Is there a way to stop this from happening and most importantly why is this happening?

Sorry, but the info is not available in the docs or someplace else.

Thanks!

You must be sure that the routes are unique.

What I did was to name routes files. To have only one with the name routes.

In this one I revered the other ones:

# Page.
GET        /wizard/:wizard/:user        server.WizardController.wizardPage(wizard: String, user: String)

# Reuse the routes from the ADAPTERS project
->         /                            adapters.Routes

Here is my example: https://github.com/pme123/scala-adapters-wizard

In your case it is the other way around (one routes forwards to the other routes for different sub-paths)

# Page.
->        /app2   app2.Routes   
->        /app3   app3.Routes   
->        /app4   app4.Routes   

# Routes from app1
GET         /doIt                            controller.doIt()
...

And that you run the app you want. Like sbt app1/run. This is necessary if app1 is not the default project - see the documentation.
