PlayFrameworkをGradleで動かしたい

前回、sbtを使ったPlayFrameworkのプロジェクト作成方法についてご紹介しました。

参考

【爆速環境構築】sbtを使ったPlayFramework2.7のプロジェクト作成方法【Java】

しかし、Gradle信者な筆者はどうにかしてPlayFrameworkをsbtでは無くGradleから実行出来ないのか？と調べてみたところ、Gradleから公式のPlayFramework用のプラグインが提供されていたので、試しに使って起動までを動作確認してみました。

手順

環境

今回は以下の環境で試してみようと思います。

Point

PlayFramework 2.6.25
Scala 2.12
Gradle 5.6.4

PlayFramework2.7以上、Scala2.13以上はサポート外

こちらのGradle-PlayFrameworkプラグインはPlayFramework2.7以上、Scala2.13以上はサポートしておらず、あくまでPlayFramework~2.6、Scala~2.12までしか正常に動かないとのことです。

試しに、PlayFramework2.7.3、Scapa2.13で試したところ、java.lang.NoClassDefFoundError: scala/Serializableエラーが出てうまく起動しませんでした>

PlayFramework2.7以上、Scapa2.13以上でも動くならかなり実用性は上がるんですけどね。。。orz

build.graldeの作成

まずはbuild.sbtに変わってbuild.gradleを作成しましょう。

plugins {
    id 'org.gradle.playframework' version '0.9'
}

def playVersion = "2.6.25"
def scalaVersion = "2.12"

repositories {
    jcenter()
    maven {
        name "lightbend-maven-release"
        url "https://repo.lightbend.com/lightbend/maven-releases"
    }
    ivy {
        name "lightbend-ivy-release"
        url "https://repo.lightbend.com/lightbend/ivy-releases"
        layout "ivy"
    }
}
play {
    injectedRoutesGenerator = true
}
dependencies {
implementation "com.typesafe.play:play-guice_${scalaVersion}:${playVersion}"
testImplementation "com.typesafe.play:play-guice_${scalaVersion}:${playVersion}"
}

plugins {

id 'org.gradle.playframework' version '0.9'

}

def playVersion = "2.6.25"

def scalaVersion = "2.12"

repositories {

jcenter()

maven {

name "lightbend-maven-release"

url "https://repo.lightbend.com/lightbend/maven-releases"

}

ivy {

name "lightbend-ivy-release"

url "https://repo.lightbend.com/lightbend/ivy-releases"

layout "ivy"

}

play {

injectedRoutesGenerator = true

}

dependencies {

implementation "com.typesafe.play:play-guice_${scalaVersion}:${playVersion}"

testImplementation "com.typesafe.play:play-guice_${scalaVersion}:${playVersion}"

}

build.sbtやprojectディレクトリは不要なので削除してしまって問題ありません。

gradle runPlayで実行

サーバーを起動する際にはgradle runPlayで実行可能です。

gradle runPlay

そしてGradleでユニットテストを行う最大の利点である、ケース単位のレポートHTMLの自動生成も活用出来ます！

出力先はデフォルトで {プロジェクトディレクトリ}/build/reports/tests/test/index.html となっています。

失敗時はこんな感じ。

しっかりとテスト結果単位でログがレポートにまとまるので調査もしやすい・・・！

このレベルのレポートが標準で出力されるのはとても嬉しいですよね！

sbtじゃ出来ない部分なので、やはり筆者はGradleに惹かれてしまいます・・・！

もちろんJaCoCoも利用可能

通常のsbt+JaCoCoで出来たガバレッジの出力についても問題無く可能です。

build.gradleに以下の一文を加えてください。

plugins {
    id 'org.gradle.playframework' version '0.9'
    id 'jacoco'   // ★追加
}
...
(略)
...

plugins {

id 'org.gradle.playframework' version '0.9'

id 'jacoco' // ★追加

}

...

(略)

...

追記したらgralde test jacocoTestReportコマンドで生成されます。

終わりに

以上のように、PlayFrameworkをsbtではなくGradleで起動する事が出来ました。

Gradleも強力なビルドツールなので、気になる方は是非試してみてください♪
