Unable to run diffChangeLog with spring boot with java 11

Hello. I am unable to get this running for my project on java 11 with spring boot. My build.gradle:

buildscript {
	ext {
		springBootVersion = '2.1.0.RELEASE'
        runList = 'main'
        diffLog = '$projectDir/src/main/resources/db/changelog/db.changelog-master.xml'
    }
	repositories {
        mavenLocal()
		mavenCentral()
	}
	dependencies {
		classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath 'org.liquibase:liquibase-gradle-plugin:2.0.1'
//        classpath 'org.liquibase:liquibase-core'
        classpath 'org.liquibase:liquibase:3.7.0-SNAPSHOT'

When running either diff or diffChangeLog, I am getting this:

This is caused by HibernateConnectionMetadata class, which I do not understand the purpose of. It just returns null/0/false for everything. So then I tried commenting out referenceDriver 'liquibase.ext.hibernate.database.connection.HibernateDriver' and replaced the line with: driver 'org.postgresql.Driver' But that amounted to getting a new exception instead:

No idea what that means since postgre driver is clearly listed as a liquibaseRuntime dependency. This may not be an issue of this project, I am rather looking for an advice how to proceed.

I am getting the same error. It is like the catalogs object is coming as null when I am using it with the MySQL database

Any help?

I had this Problem: I defined the ref URL in the liquibase.properties file. And put a Multiline string there.

referenceUrl:"hibernate:spring:de.cop.business.model\
  ?dialect=org.hibernate.dialect.SQLServerDialect"

I forgot that Properties is not yaml and " is invalid.

Removing the " worked. Parsing the URI should really be validated before executing on it.
