我尝试的事情：
gradle clean assemble pid手动检查）谢谢你看看！
答案 0 :(得分：2)
问题是我的changelog和第5a周脚本都在做同样的事情，即创建数据库。在更改日志内部有一行代码include file: 'week-5A.groovy'。因此，当执行更改日志时，它会创建数据库，然后执行第5A周，后者继续执行相同的操作，因此引发了异常。
答案 1 :(得分：0)
当hibernate尝试执行sql语句时 作为流程
CREATE TABLE PUBLIC.quote (id BIGINT AUTO_INCREMENT NOT NULL, version BIGINT NOT NULL, text VARCHAR(255) NOT NULL, CONSTRAINT quotePK PRIMARY KEY (id)) [42101-191] [Failed SQL: CREATE TABLE PUBLIC.quote (id BIGINT AUTO_INCREMENT NOT NULL, version BIGINT NOT NULL, text VARCHAR(255) NOT NULL, CONSTRAINT quotePK PRIMARY KEY (id))]
数据库发现这个名为“PUBLIC.quote”的表存在。
“自动数据库迁移”选项可能不正确。您可以在开发环境中将“dbCreate”选项设置为“update”
答案 2 :(得分：0)
在你的liquibase scrips周围进行一些先决条件检查是个好主意：
http://www.liquibase.org/documentation/preconditions.html
类似的东西：
preConditions(onFail:"MARK_RAN") {
not {
tableExists(tableName: "quote")
}
}
