如何为插件添加依赖项？

Question

我想在gradle中使用flyway，如何为插件添加依赖项？

plugins {
    id "org.flywaydb.flyway" version "5.2.4"
}
ext {
    mysqlVersion = '8.0.13'
}
dependencies {
        runtimeOnly("mysql:mysql-connector-java:${mysqlVersion}")
}

我跑步时

gradle flywayMigrate

我遇到错误：

FAILURE: Build failed with an exception.

* What went wrong:
