I’m using liquibase since 12+ years and totally happy with it.  
In my latest project, I have a custom changeset for a given context:

```auto
    <changeSet id="migrateUserSettings" author="dominik" context="!ci">
        <customChange class="de.hub28.hwg.isplaner.usersettings.MigrateUsersettingsLiquibaseChange">
        </customChange>
        <rollback>
        </rollback>
    </changeSet>

```

If I run Liquibase locally, the class was already compiled by the IDE into target/classes directory, is picked up by liquibase and executed successfully. ✅

Within my CI pipeline, I don’t need this changeset run, so therefore I declare the

```
context="!ci"

```

part. The command used by the pipeline is

```
   mvn liquibase:update -Dliquibase.contexts=ci 

```

in order to EXCLUDE the mentioned CI context. But I got an ClassNotFoundException. (see below)

```auto
[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:4.29.0:update (default-cli) on project isplaner:
[ERROR] Error setting up or running Liquibase:
[ERROR] liquibase.exception.ChangeLogParseException: liquibase.parser.core.ParsedNodeException: liquibase.exception.CustomChangeException: java.lang.ClassNotFoundException: de.hub28.hwg.isplaner.usersettings.MigrateUsersettingsLiquibaseChange
[ERROR] -> [Help 1]` `org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.liquibase:liquibase-maven-plugin:4.29.0:update (default-cli) on project isplaner: ` `Error setting up or running Liquibase:` `liquibase.exception.ChangeLogParseException: liquibase.parser.core.ParsedNodeException: liquibase.exception.CustomChangeException: java.lang.ClassNotFoundException: de.hub28.hwg.isplaner.usersettings.MigrateUsersettingsLiquibaseChange

```

How can I remain that changeset in the changelog.xml but prevent execution in the CI pipeline ?
