Gradle Flyway迁移任务-无法获得连接

Question

我正在开发API，并在Gradle中使用Flyway迁移工具。当我运行flywayMigration任务时，出现“无法获取连接”错误。

我尝试了以下URL值-没有一个起作用。

url = "jdbc:mysql://localhost:3306/dataloader"
url = "jdbc:mysql://localhost:3306"
url = "jdbc:mysql://localhost:3306; databasename=dataloader"

build.gradle
---------------
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "mysql:mysql-connector-java:5.1.37"
      project(":dataloader-orm")
    }
}

plugins {
    id "org.flywaydb.flyway" version "5.0.7"
}

group 'com.example.project'
version '0.0.1-SNAPSHOT'

flyway{

    url = 'jdbc:mysql://localhost:3306/dataloader'
    user = 'root'
    password = 'mypassword'
    driver = 'com.mysql.jdbc.Driver'
    schemas = ["test"]
    placeholderReplacement=false
}


V1__initial.sql
----------------

insert into table test values(1);
