How to Fix NoClassDefFoundError for SnowflakeDatabase in Liquibase with Spring Boot and SQL Server

If you're a developer working with Spring Boot and Liquibase, you may have encountered a frustrating error when attempting to launch your application. Specifically, if you're using a SQL Server database and running into a NoClassDefFoundError related to SnowflakeDatabase, you’re not alone. This article walks you through understanding the problem and how to effectively resolve it.

Why Is This Happening?

This error arises because your application is attempting to reference a class (SnowflakeDatabase) that is not included in your dependencies. Although you're working with an SQL Server database, the presence of a Snowflake reference indicates a potential mismatch or conflict in your dependencies, likely caused by the version of Liquibase you are using.

Solution Overview

To rectify this issue, we recommend updating the version of Liquibase in your project. The effective solution we found was to downgrade the liquibase-core version to 4.15.0. This change resolves the incompatibility and ensures that Liquibase properly interacts with your SQL Server database without referencing Snowflake.

Step-by-Step Solution

Step 2: Verify Your Compatibility

Before running your application again, ensure that all the other dependencies are compatible with Liquibase 4.15.0. You can check the documentation for each dependency to confirm compatibility.

Step 3: Clean and Rebuild Your Project

After making the changes, clean and rebuild your project. This step ensures that all old versions of classes are removed and your application is using the latest code.

Step 4: Test Your Application

Once your project is rebuilt, run your Spring Boot application. If everything was set up correctly, the previous error regarding SnowflakeDatabase should no longer appear, and your application should be able to start successfully.

Conclusion

Encountering a NoClassDefFoundError related to SnowflakeDatabase while using Liquibase with SQL Server in Spring Boot can be frustrating. However, by adjusting your liquibase-core version to 4.15.0, you can resolve this issue and continue developing your application without further interruptions.
