activator createModule [module_name]
Add the module to the main build file build.sbt:
lazy val [module_name] = (project in file("modules/[module+name]")
.dependsOn(common)
Add a dependency to the common project:
.dependsOn([module_name]).aggregate([module_name])
Add the module to the reverse router in common:
aggregateReverseRoutes := Seq(..., [module_name])
Add a route for the module in conf/routes:
-> /[module_name] [module_name].Routes
If you are using IntelliJ you might want to add the folder modules/common/target/scala-2.11/classes as a dependency for the module, by going to File → Project Structure → Modules → [module_name] and selecting the Dependencies tab. Press the green plus, then select JARs or directories... and select the beforementioned folder. This enables IntelliJ to detect reverse routers on your classpath.
