java.lang.NoClassDefFoundError: liquibase/Scope Liquibase 3.5.2 Spring Boot 1.5.15

[eninja]

Thanks for this extension!
Perhaps more a question than a bug: is there a minimum version of liquibase it is compatible with?

I have no problem with:
Spring Boot 2.7.0
Liquibase 4.9.1

but when I added it to:
Spring Boot 1.5.15
Liquibase 3.5.2

Application run failed with exception:

I have also tried add system property liquibase.scan.packages, but result is the same.

The issue is that this repository depends on the liquibase.Scope class, but that class was only added in Liquibase 3.7.

In other words, in its current state, Liquibase Sessionlock is not compatible with Liquibase 3.6 or below. The README references 3.7, so I presume that is the minimum supported version.

Thanks,
I have created #20 to clarify this

[blagerweij]

Hey @eninja , thanks for the report. I've added some reflection magic to detect older Liquibase versions, so that loading the extension does not break on older versions. Also, I've added a few older versions to the build matrix to verify compilation and unit-tests. Please let me know whether the sessionlock works on 3.5.x.

Fixed by #22

@blagerweij thank you very much! it works with dependencies mentioned above.
