Unity IAPとGooglePlayBillingのclassが競合してAndroidがビルドできない問題の対策

Posted at

こんにちは。もぐめっとです。

実はタキシードを着たことがあります。
だから何？という感じですね。すみません。調子乗りました。

今回は久々にUnityビルドの沼にハマったので解決策を掲示しておきます。

答えを知りたい場合は対策まで飛んじゃってください。

エラー内容

アプリ内課金（In App Purchase）を導入したく、下記のドキュメントを見て導入をすすめてました。

しかし、Unity IAPとplay-unity-pluginsを導入した状態でAndroid用にビルドすると、ひたすらにduplicateなエラーが出力されます。

Execution failed for task ':launcher:checkReleaseDuplicateClasses'.

こいつのおかげでandroidがビルドできません。

原因

googleのドキュメントはUnity IAPを手動でいれた前提で進めているのですが、最近はUnityPackageManagerを導入していれる手順になっております。
UnityPackageManagerでいれると ./Library/PackageCacheのファイルを参照してビルドするのですが、この中にあるbilling-3.0.3.aarを抹消してもビルド時にしつこく復活してしまい、結果競合が起こってました。

ビルド後のファイルの様子

$ find . | grep billing-3
./Temp/StagingArea/aar/billing-3.0.3.aar
./Temp/gradleOut/unityLibrary/libs/billing-3.0.3.aar
./Library/PackageCache/com.unity.purchasing@3.1.0/Plugins/UnityPurchasing/Android/billing-3.0.3.aar.meta
./Library/PackageCache/com.unity.purchasing@3.1.0/Plugins/UnityPurchasing/Android/billing-3.0.3.aar

対策

ちなみにissueにも上がっておりますが、Googleの言うことはきくな！GooglePlayBillingは消せ！と言ってる人がいました。

しかし見ず知らずの意見を聞くのも微妙なので、頑張りました。
結果、Library/PackageCacheの中身をPackagesにコピーしてくることで解決しました！

手順は下記を実施するだけです！

$ cp -r ./Library/PackageCache/com.unity.purchasing@* ./Packages
$ rm com.unity.purchasing@3.1.0/Plugins/UnityPurchasing/Android/billing-*

この状態でビルドすると、PackageManagerがレポジトリからではなくローカルの方を参照するようになります。

Packages/packages-lock.json
...
    "com.unity.purchasing": {
-     "version": "3.1.0",
+     "version": "file:com.unity.purchasing@3.1.0", 
      "depth": 0,
-     "source": "registry",
+     "source": "embedded",
      "dependencies": {
        "com.unity.ugui": "1.0.0",
        "com.unity.modules.unityanalytics": "1.0.0",
        "com.unity.modules.unitywebrequest": "1.0.0",
        "com.unity.modules.jsonserialize": "1.0.0",
        "com.unity.modules.androidjni": "1.0.0"
+      }
-      },
-      "url": "https://packages.unity.com"
...

これでduplicateな悩みからはさよならバイバイ！

※ただし、更新とかは手動でやらないといけなくなるので要注意です。

まとめ

Library/PackageCache/com.unity.purchasing@*を./Packagesにコピってくれば解決！

UnityIAP側がGooglePlayBillingをフォローしてくれれば一番いいんですけどね。。悔やまれます。
