Upgrade from oracle-r2dbc version 0.4.0 to 1.0.0 is resulting in class cast exception while update. about oracle-r2dbc

[mp911de]

FWIW, Spring Framework 6 is expected to go GA in mid-November. The new Reactor Core 3.5 will be GA early November, allowing R2DBC drivers to upgrade in time to be included in the Spring Framework 6 /Spring Boot 3 support.

Hi @rathoreamrsingh. Very sorry to see this error yet again! I believe it is a duplicate of #89. Can you check what I wrote there and see if it helps?

Hi @Michael-A-McMahon
Thanks a lot for the pointer.
I tried upgrading all the dependencies.
But this doesn't seems to be working.
Do you have any sample project where version 1.0.0 is working I can take some hint from there.

By the way below is my build gradle file which I am using for my project.
Please have a look and let me know what I am doing wrong.

It looks like you may need to stay on the 0.4.0 release for now, as it is the only version compatible with Spring Data R2DBC. However, it looks like a new release of Spring Data is on the way which will be compatible with Oracle R2DBC 1.0.0. Keep an eye on #89 to see what we find.
