Currently I'm experimenting with Liquibase and trying to run a customChange. The Project is Spring-Webflux based, compiled into a fat jar. Every time I try to run the Liquibase with the customChange I've created, I ran into
[ERROR] Error setting up or running Liquibase:
[ERROR] liquibase.exception.ChangeLogParseException: liquibase.parser.core.ParsedNodeException: liquibase.exception.CustomChangeException: java.lang.ClassNotFoundException: com.abl.rjmdb.liquibase.DoNothingChange
DoNothingChange:
package com.abl.rjmdb.liquibase;
import liquibase.change.AbstractChange;
import liquibase.database.Database;
import liquibase.statement.SqlStatement;
public class DoNothingChange extends AbstractChange {
public String getConfirmationMessage() {
return "OK";
}
public SqlStatement[] generateStatements(Database database) {
return new SqlStatement[0];
}
}

rjmdb.imlI try to run the Liquibase with - mvn clean install -Plocal and it works fine as far as I don't use any custom change.
I've been told to export the custom changes to a different jar but it feels like it contradicts the entire far jar philosophy.
I managed to run custom changes by creating a module (jar) of the custom changes and then use it as a dependency in the maven-liquibase-plugin.
