Play Maven plugin doesn't seem to be generating Routes

[Nir]

When I start play application using `mvn play2:start` it doesn't seem to compile any routes. But if I do `sbt run` on same project it does. 

pom.xml

    <plugin>

        <groupId>com.google.code.play2-maven-plugin</groupId>

        <artifactId>play2-maven-plugin</artifactId>

        <version>${play2.plugin.version}</version>

        <extensions>true</extensions>

        <configuration>

            <!-- if using controllers without dependency injection; default value is "injected" -->

            <routesGenerator>static</routesGenerator>

        </configuration>

    </plugin>

I am using Guice (default DI) so not sure what to put in routesGenerator. I don't see any documents either.

Here's the console output for `sbt run` after I hit localhost:9000

(Server started, use Enter to stop and go back to the console...)

I have removed HOmeController.index , but point is it atleast scanned all the routes and tried to compile.

WIht `mvn play2:run` I get following after I hit localhost:9000

AM I missing anything here with play-maven configuration?

Hi Nir

Remove 'rootsGenerator' setting, default value will work with DI.

It didn't help.

Either Routes itself of Applicaiton itself is not getting initialize I think when I use 'mvn play2:run'

Here's the another test I did:

I removed Module config which bind the dependency of PostRepository. 

I started application using `sbt run` and as soon as I hit server I get following error which means its at least trying to init the app

No implementation for v1.post.PostRepository was bound.

  while locating v1.post.PostRepository

    for the 2nd parameter of v1.post.PostResourceHandler.<init>(PostResourceHandler.scala:44)

  while locating v1.post.PostResourceHandler

    for the 2nd parameter of v1.post.PostControllerComponents.<init>(PostActionBuilder.scala:97)

  while locating v1.post.PostControllerComponents

    for the 1st parameter of v1.post.PostController.<init>(PostController.scala:20)

  at play.api.DefaultApplication.class(Application.scala:235)

  while locating play.api.DefaultApplication

  while locating play.api.Application

With `mvn play2:run` it didn't complain about it and just started but did not recognize route.

something is still missing here with play maven setup.

I sometimes  see above messages in UI (especially if I manually compile and then do mvn play2:run) instead of just `mvn play2:run` .

SOLVED!

I forgot to use 'play2' as packaging in my pom.xml !

<packaging>play2</packaging>
