}

dependencies {
    liquibaseRuntime 'org.liquibase:liquibase-core:3.10.3'
    // 其他依赖
}

task runLiquibaseScript(type: JavaExec) {
    // 配置Liquibase任务的属性
    main = 'liquibase.integration.commandline.Main'
    classpath = configurations.liquibaseRuntime
    args "--changeLogFile=path/to/changelog.xml", "--url=jdbc:mysql://localhost:3306/mydb", "--username=root", "--password=secret", "update"
}

task runBackupScript(type: Exec) {
    // 配置备用脚本任务的属性
    commandLine 'path/to/backup_script.sh'
}

runLiquibaseScript.doLast {
    if (runLiquibaseScript.exitValue != 0) {
        throw new GradleException("Liquibase脚本执行失败")
    }
