问题
I'm working on Spring batch and Spring Cloud Data Flow example. In this example, I've developed spring-cloud-data-flow-server and MySQL DB instead of default H2 DB by taking reference from Database Configs for MySQL DB
It looks like there is a issue with the Flyways and MySQL version as latest version of Flyways doesn't pickup the latest version of MySQL DB.
Error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.internal.command.DbMigrate$FlywayMigrateException: Migration failed !

回答1:
MySQL v5.5 doesn't accept an argument for the DATETIME datatype. Update your query to the following:
CREATE TABLE TASK_LOCK (
LOCK_KEY CHAR(36) NOT NULL,
REGION VARCHAR(100) NOT NULL,
CLIENT_ID CHAR(36),
CREATED_DATE DATETIME NOT NULL, -- note the omitted (6) argument --
constraint LOCK_PK primary key (LOCK_KEY, REGION)
);
Consider using the same MySQL version for local development as your remote deployment servers. This way, you won't be surprised by incompatibilities between the environments your application will run within.

Can you please try the latest version of flyway-core? Some issues were fixed in this area.
<dependency>
<groupId>org.flywaydb</groupId>
<artifactId>flyway-core</artifactId>
<version>6.4.1</version>
</dependency>
