liquibase diff does not works - postgresql

Question

I am attempting to make Spring Boot 2.2.x application (Java 13) with Code-First approach using Hibernate and Liquibase. I would like to generate migrations base on difference between Entities object and database.
OS - Win 10 and Mint 18
Build system - gradle 6.0.
Database - Postgres SQL.
I installed liquibase utilities (3.8.2).
My gradle script:
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath 'net.ltgt.gradle:gradle-apt-plugin:0.18'
classpath 'org.postgresql:postgresql:42.2.9'
classpath 'org.liquibase:liquibase-core:3.8.2'
classpath "org.liquibase:liquibase-gradle-plugin:2.0.2"
}
}
plugins {
id 'org.springframework.boot' version '2.2.1.RELEASE'
id 'io.spring.dependency-management' version '1.0.8.RELEASE'
id 'org.liquibase.gradle' version '2.0.2'
id 'java'
}
group = 'com.goodt.drive'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '13'
targetCompatibility = '13'
diff.dependsOn compileJava
diffChangeLog.dependsOn compileJava
generateChangelog.dependsOn compileJava
dependencies {
liquibaseRuntime 'org.liquibase:liquibase-core:3.8.2'
liquibaseRuntime "jakarta.xml.bind:jakarta.xml.bind-api:2.3.2"
liquibaseRuntime 'org.springframework.boot:spring-boot:2.2.1.RELEASE'
liquibaseRuntime 'org.liquibase:liquibase-groovy-dsl:2.0.1'
liquibaseRuntime 'org.postgresql:postgresql:42.2.9'
liquibaseRuntime 'org.hibernate:hibernate-core:5.4.10.Final'
liquibaseRuntime 'ch.qos.logback:logback-core:1.2.3'
liquibaseRuntime 'ch.qos.logback:logback-classic:1.2.3'
liquibaseRuntime sourceSets.main.output
}
def dbChangeLog = "$projectDir/src/main/resources/db/changelog/changelog.xml"
def generatedChangeLog = "$projectDir/src/main/resources/db/changelog/generated_changelog.xml"
liquibase {
activities {
main {
changeLogFile dbChangeLog
outputFile generatedChangeLog
driver "org.postgresql.Driver"
classpath "$projectDir/lib/postgresql-42.2.9.jar"
url "jdbc:postgresql://localhost:5432/webportal"
username "developer"
password "123"
referenceUrl "hibernate:spring:com.wissance.webportal.application.model.entities?dialect=org.hibernate.dialect.PostgreSQL94Dialect"
//referenceDriver 'liquibase.ext.hibernate.database.connection.HibernateDriver'
}
}
}
When i am runnung liquibase diff command from gradle script like this: .\gradlew.bat diff i am getting following output:
> Task :diff

Answer 1

The stack trace indicates that Liquibase Cannot find database driver and Driver class was not specified and could not be determined from the url (hibernate:spring:com.wissance.webportal.application.model.entities?dialect=org.hibernate.dialect.PostgreSQL94Dialect)
This indicates that you should add the liquibase-hibernate jar to your dependencies and uncomment the referenceDriver line in your gradle script.

Answer 2

I updated liquibase (in gradle) to version 3.8.4
I added liquibaseRuntime lines with liquibase-hibernate and spring-data-jpa
I added to liquibase-hibernate and spring-data-jpa classpath {} section of gradle script.
One more addition, i write an article about how to use liquibase you could find it here: https://m-ushakov.medium.com/code-first-with-spring-boot-hibernate-and-liquibase-48f5c9998d95

Not sure if it's related to the errors you are experiencing or not, but Liquibase recently posted a 3.8.4 version that corrects some Spring Boot errors with Java 9+. https://www.liquibase.org/2019/12/liquibase-3-8-4-released.html
I'd try running that to see if it resolves the issue for you.
