让 Play Framework 与 Gradle 和 IntelliJ Idea 配合使用

Question

I'm trying to build my web application with Play Framework using Gradle as a build tool. My IDE is IntelliJ Idea .

I use Play with Java so I don't want to use SBT in my project. But it seems Play's not supported fully by IntelliJ Idea because the project structure is quite different. IntelliJ can't recognize it.

After a while googling, I found a solution, adding this script in build.gradle :

idea {
    module {
        sourceDirs += file("app")
        testSourceDirs += file("test")
        scopes.COMPILE = [plus: [configurations.play], minus: []]
        scopes.RUNTIME = [plus: [configurations.playRun], minus:[configurations.play]]
        scopes.TEST = [plus: [configurations.playTest], minus: [configurations.playRun]]
    }
}

But there is a problem, each time I open the project, I have to re-run idea task to make IntelliJ recognize the Play's structure.

Is there any way that's better than mine?

Thank you so much!

My build.gradle

plugins {
    id 'play'
    id 'idea'
}

def playVersion = "2.6.7"
def scalaVersion = System.getProperty("scala.binary.version", /* default = */ "2.11")

model {
    components {
        play {
            platform play: playVersion, scala: scalaVersion, java: '1.8'
            injectedRoutesGenerator = true

            sources {
                twirlTemplates {
                    defaultImports = TwirlImports.JAVA
                }
            }
        }
    }
}


def dependencyFor(String lib, String scalaVersion, String version) {
    return lib + "_" + scalaVersion + ":" + version
}

dependencies {
    play dependencyFor("com.typesafe.play:play-guice", scalaVersion, playVersion)
    play dependencyFor("com.typesafe.play:play-logback", scalaVersion, playVersion)
    play dependencyFor("com.typesafe.play:filters-helpers", scalaVersion, playVersion)
    play dependencyFor("com.typesafe.play:play-java-jpa", scalaVersion, playVersion)

    play "org.hibernate:hibernate-core:5.4.2.Final"
    play "com.h2database:h2:1.4.197"

}

repositories {
    jcenter()
    maven {
        name "lightbend-maven-releases"
        url "https://repo.lightbend.com/lightbend/maven-release"
    }
    ivy {
        name "lightbend-ivy-release"
        url "https://repo.lightbend.com/lightbend/ivy-releases"
        layout "ivy"
    }
}

idea {
    module {
        sourceDirs += file("app")
        testSourceDirs += file("test")
        scopes.COMPILE = [plus: [configurations.play], minus: []]
        scopes.RUNTIME = [plus: [configurations.playRun], minus: [configurations.play]]
        scopes.TEST = [plus: [configurations.playTest], minus: [configurations.playRun]]
    }
}

I'm using Java 8 , Gradle 5.4 , Play 2.6.7

The below setup works now with some finessing required to get the rest of your dependencies up and running.

plugins {
    id 'play'
    id 'idea'
}
# replace with
plugins {
    id 'idea'
    id 'org.gradle.playframework' version '0.9'
}

The next step is to execute gradle idea and you should be able to just import the folder and intellij. If that is not the case go to Build tools -> Gradle and select use gradle
