Spring boot upgrade from 2.6.6 to 2.7.1 - dev.miku:r2dbc-mysql-CodePudding

I am upgrading spring boot from 2.6.6 to 2.7.1 and running into r2dbc-mysql error.

With Spring boot 2.6.6, I am using r2dbc-mysql.

runtimeOnly 'dev.miku:r2dbc-mysql'

Getting compilation error after upgrading Spring boot to 2.7.1.

So, commented the above from build.gradle and getting the error below at runtime.

Caused by: java.lang.IllegalStateException: Unable to create a ConnectionFactory for 'ConnectionFactoryOptions{options={database=test, host=app-dev-mysql.sdferf1234.us-east-2.rds.amazonaws.com, driver=mysql, password=REDACTED, protocol=, port=3306, user=test}}'. Available drivers: [ pool ]

CodePudding user response：

Try with implementation group: 'dev.miku', name: 'r2dbc-mysql', version: '0.8.2.RELEASE' instead of runtimeOnly 'dev.miku:r2dbc-mysql', I had the same issue and it worked for me.
