編集2024/04/20 03:38Springプロジェクトを作成し、Herokuにデプロイしましたがエラーが出ています。
デプロイした時にエラーが発生します。（ > Could not resolve all artifacts for configuration ':classpath'.・・・）
エラーの原因として予想は、下記の問題なのかと思うのですが、解決できません。
・おそらくgradleのバージョンとSpring もしくはJavaのバージョンが合ってない？
・build.gradleの設定ができていない。

Herokuに詳しくないのですが、OpenJDK 8 (1.8)で動いているように見えます。（Spring Boot 3はJDK17以上が必要となります）
Installing OpenJDK 1.8... done
https://devcenter.heroku.com/ja/articles/java-support#supported-java-versions
日本語版の方には記載がないのですが、OpenJDK 21も設定できるようです。
https://devcenter.heroku.com/articles/java-support#supported-java-versions
尚、Herokuの方は21で動いておりますでしょうか。もし、エラーメッセージに1.8や8などの文字が含まれているなら、Herokuの方がOpenJDK 8で動いている可能性があります。
