Flyway clean不能以小写形式丢弃H2表

Question

这是我的flyway配置:

url: jdbc:h2:./target/test;MODE=MYSQL;INIT=CREATE SCHEMA IF NOT EXISTS "test";

这就是我在我的测试套件中初始化它的方法:

Flyway flyway = new Flyway();
flyway.setDataSource(APP.getConfiguration().getDatabaseUrl(), APP.getConfiguration().getDatabaseUser(),
        APP.getConfiguration().getDatabasePass());
flyway.setBaselineOnMigrate(true);
flyway.setSchemas("test");
flyway.clean();
flyway.migrate();

这很好,但只是第一次.任何后续时间具有相同的架构,我得到错误:

如果我flyway.clean()从初始化中删除,由于数据库已经被填充,我得到一些错误与迁移不起作用,因此所有表都可以.

以前,在我添加之前,这个工作正常MODE=MYSQL;.以下是创建表的方式V1_migration.sql:

CREATE TABLE my_table (id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, session_id INT, token VARCHAR(50), CONSTRAINT s_id FOREIGN KEY (session_id) REFERENCES user_sessions(id));

到底是怎么回事？为什么Flyway不能丢桌子？

必须将H2数据库配置为不区分大小写

DATABASE_TO_UPPER=false;
