How can I create a new project which compiles in IntelliJ Idea?

[Louise Elmose Hedegaard]

Hi,

I want to create a new Play framework project which is able to compile in IntelliJ idea (community edition 15).

I tried following the instructions described on the Play framework homepage:

https://www.playframework.com/documentation/2.1.x/NewApplication

but without any luck:

a) Creating project with the activator command (activator version 1.3.7).

NB: The Play framework page says "play", but I guess it should be "activator" instead?

I execute the following:

1) activator new myFirstApp

2) 3 (minimal-java)

3) cd myFirstApp

4) activator idea

I get the following error:

[error] Not a valid command: idea (similar: eval, alias)

[error] Not a valid project ID: idea

[error] Expected ':' (if selecting a configuration)

[error] Not a valid key: idea (similar: clean)

[error] idea

[error]     ^

If I open the project in idea, all references to play packages are not recognized by idea ("play" is red in the package reference).

b) Create project via sbt

1) I follow the directions described on the Play framework page - when I execute "sbt" I get an error: 

play#sbt-plugin;2.5.0: not found

Does anybody have a simple description of how I can create a new Play framework project which can compile in IntelliJ Idea?

Thanks,

-Louise

Hi Louise,

Have you try to type idea after entering activator?

1) type "activator" enter

2) type "idea" enter

May it help.

Thanks.

You can find the correct instructions here:

https://playframework.com/documentation/2.5.x/IDE#IntelliJ

If the dependencies aren't resolved, open the sbt tool tab in IntelliJ and click on the refresh button.

I execute the following:

1) activator new myFirstApp

2) 3 (minimal-java)

3) cd myFirstApp

4) activator idea

Install the Scala plugin, and import the newly create Play project as an existing SBT project.

Hi Azwar,

Thank you for your answer.

Unfortunately it did not help - I get the same result while executing "activator idea" or "activator" + enter, and then idea + enter.

Hi Steve,

Thank you for your answers, but unfortunately none of the described steps help - "play" is still red in the package import in e.g. the controllers.

Any other suggestions are appreciated.

Hi Igmar,

Thank you for your answer.

I already had the Scala plugin installed, and following your description still does not enable me to get dependencies resolved in Idea.

The only thing that works is if I use the websocket example from the Play framework homepage, and add my code to that project. So maybe it is the newer versions of the Play framework that does not work with Idea?
