Unable to resolve persistence unit root URL

See original GitHub issue

Hello,

I’ struggling with liquibase diff generation on a very simple project which uses newest Spring Boot 1.5.8.RELEASE. I have empty, running database (MariaDB 10.3.2) and a simple domain object. I wan’t to generate initial changelog based on this domain

build.gradle:

	ext {
		springBootVersion = '1.5.8.RELEASE'
	        lombokVersion = '1.16.18'
	        mariadbJdbcVersion = '2.1.2'
	}
	dependencies {
		classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"

		//GRADLE LIQUIBASE PLUGIN DEPENDENCIES
		classpath "org.springframework:spring-beans:4.3.12.RELEASE"
		classpath "org.springframework.boot:spring-boot-starter-data-jpa:$springBootVersion"
	        classpath "org.mariadb.jdbc:mariadb-java-client:$mariadbJdbcVersion"
		classpath "org.hibernate:hibernate-core:5.0.12.Final"
		classpath "gradle.plugin.org.liquibase:liquibase-gradle-plugin:1.2.4"
	        classpath "org.liquibase:liquibase-core:3.5.3"
		classpath "org.liquibase.ext:liquibase-hibernate5:3.6
	}
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'groovy'
apply plugin: 'org.liquibase.gradle'

jar.baseName = 'myApplication'
group = 'my.group.id'
version = '1.0-SNAPSHOT'
sourceCompatibility = 1.8

dependencies {
	compile "org.springframework.boot:spring-boot-starter:$springBootVersion"
	compile "org.springframework.boot:spring-boot-starter-data-jpa"
	compile "org.projectlombok:lombok:$lombokVersion"

	compile "org.mariadb.jdbc:mariadb-java-client:$mariadbJdbcVersion"
	compile "org.liquibase:liquibase-core:3.5.3"
}

liquibase {
    activities {
        main {
            driver 'org.mariadb.jdbc.Driver'
            url 'jdbc:mariadb://localhost:3306/greeterDB'
            username 'root'
            password 'mariadb_pass'

            changeLogFile 'src/main/resources/db/changelog/changelog-master.xml'

            referenceUrl 'hibernate:spring:my.group.id.persistence.domain?dialect=org.hibernate.dialect.MySQLDialect'
        }
    }
}

Domain object (only one in this package):

package my.group.id.persistence.domain;

import lombok.*;
import javax.persistence.*;

@Entity
@AllArgsConstructor
@NoArgsConstructor
@Builder
@Getter
@ToString
public class Greeting {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private String message;
    private String type;
}

Error during liquibase diff execution:

I know that this issue was mentioned under ticket 68. But I wasn’t able to resolve it be altering different hibernate/liquibase/liquibase-ext dependency versions.

Still not working on version 3.8, mvn compile && mvn liquibase:diff makes no difference, we are still getting aforementioned error… So we have to remain on version 3.6 which works, but lacks some bugfixes which would be nice to have…

I am also suffering from this issue. I am using maven plugin. Version 3.6 was working correctly (but it had other bugs like index regeneration during diffs). Bumping to 3.7 introduces this error. Can anyone take a look? This bug makes 3.7 pretty much unusable.
