gradle build failed with jooq configuration: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

Question

伙計們。

我正在構建一個 spring 引導服務。 現在，我將其設置為使用jooq查詢本地 MySQL 實例。

但是，. ./gradlew build給出錯誤Unable to load class 'com.mysql.jdbc.Driver' 。

我錯過了什么嗎？

更多信息

我能夠在 IntelAB 中看到com.mysql.jdbc.Driver ZA2F2ED4F8EBC2CBB14C21A29DC0

這是我的 gradle 腳本。

我的錯。

我錯過了這里提到的buildscript { }塊： https://www.jooq.org/doc/latest/manual/code-generation/codegen-gradle 。

添加以下部分后，現在我的 gradle 構建工作。

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
    }

    dependencies {
        classpath 'org.jooq:jooq-codegen:3.16.2'
        classpath 'mysql:mysql-connector-java:8.0.27'
    }
}
