Mockitoの検証のため環境構築をした
検証環境
次のコマンドでgradleを導入
$ sdk install gradle
$ gradle -v ------------------------------------------------------------ Gradle 8.7 ------------------------------------------------------------ Build time: 2024-03-22 15:52:46 UTC Revision: 650af14d7653aa949fce5e886e685efc9cf97c10 Kotlin: 1.9.22 Groovy: 3.0.17 Ant: Apache Ant(TM) version 1.10.13 compiled on January 4 2023 JVM: 17.0.5 (Eclipse Adoptium 17.0.5+8) OS: Linux 5.10.16.3-microsoft-standard-WSL2 amd64
