Today I did clone the jmix-ui-samples-2.
I am not able to change the database for the Main Data Store
You see the Question sign.
As I am working with
Jmix version: 2.6.1
Jmix Studio Plugin Version: 2.6.2-252
IntelliJ version: IntelliJ IDEA 2025.2 (Ultimate Edition)
it might be a problem of IntelliJ ?
Is it possible to have somewhere indicated, with which newest IntelliJ the actual Jmix Studio is working ?
Regards
Felix
Hi Felix!
The datasource in jmix-ui-samples-2 is not a basic Jmix datasource. It is designed to create a datasource per user session to separate different user data environments. This is why Studio does not recognize the datasource.
As mentioned in the project’s README, you can simply start the application using the following command:
./gradlew bootRun
You can try to use default Studio run configuration, but you should skip applying Liquibase scripts as they will be applied when you open localhost:8080/ui-samples.
IntelliJ offers plugins only compatible with current IDE version. Jmix Studio plugin version includes postfix which indicates supported IDE version. For instance, ***-252 indicates that plugin can be used in IntelliJ IDEA 2025.2.
Hi Roman
Thank you for these explanations.
The samples are great and any beginner will use them. So it is in my point of view not very helpfull, if a potential user gets error messages which are not to solve ;/ If I can be in any help, let me know !
Thank you for the explanation of the ***-252 too. Is this written somewhere already and I didn’t see it ? Perhaps you should update Versioning – Jmix 
Best regards
Felix
Versioning – Jmix - is URL for framework versioning. Probably, we can add information to Web Application Development Tools | Download Jmix Studio page. We will discuss with colleges, thank you!
