How to configure Grails 3.1.1 to use Hibernate 5

Question

How do I make Grails 3.1.1 user Hibernate 5?

The following actions report Hibernate version 4.3.11.Final: In Grails 3.1.1

1. grails create-app hello311
2. edit BootStrap.groovy as shown below
3. grails run-app

Console shows: Hibernate version is: 4.3.11.Final

class BootStrap {
    def init = { servletContext ->
        println "Hibernate version is: ${org.hibernate.Version.getVersionString()}"
    }
    def destroy = {}
}

My build.gradle is unedited. The create-app command resulted in the following build.gradle file:

    buildscript {
    ext {
        grailsVersion = project.grailsVersion
    }
    repositories {
        mavenLocal()
        maven { url "https://repo.grails.org/grails/core" }
    }
    dependencies {
        classpath "org.grails:grails-gradle-plugin:$grailsVersion"
        classpath "com.bertramlabs.plugins:asset-pipeline-gradle:2.5.0"
        classpath "org.grails.plugins:hibernate4:5.0.0"
    }
}

version "0.1"
group "hello311"

apply plugin:"eclipse"
apply plugin:"idea"
apply plugin:"war"

apply plugin:"org.grails.grails-gsp"

ext {
    grailsVersion = project.grailsVersion
    gradleWrapperVersion = project.gradleWrapperVersion
}

repositories {
    mavenLocal()
    maven { url "https://repo.grails.org/grails/core" }
}

dependencyManagement {
    imports {
        mavenBom "org.grails:grails-bom:$grailsVersion"
    }
    applyMavenExclusions false
}

dependencies {
    compile "org.springframework.boot:spring-boot-starter-logging"
    compile "org.springframework.boot:spring-boot-autoconfigure"
    compile "org.grails:grails-core"

    compile "org.grails.plugins:hibernate4"
    compile "org.hibernate:hibernate-ehcache"
    console "org.grails:grails-console"

    testRuntime "org.seleniumhq.selenium:selenium-htmlunit-driver:2.47.1"
    testRuntime "net.sourceforge.htmlunit:htmlunit:2.18"
}

task wrapper(type: Wrapper) {
    gradleVersion = gradleWrapperVersion
}

assets {
    minifyJs = true
    minifyCss = true
}

Changing the hibernate4 dependency to hibernate5 does not work.

Answer 1

In build.gradle change the classpath dependency for the hibernate4 plugin at the top of the file in the buildscript{ dependencies {... section as follows:

classpath "org.grails.plugins:hibernate5:5.0.1"

The classpath section is there for the Gradle scrips like schemaExport, and that section does not support auto versioning.

Change the compile hibernate4 plugin dependency to the following:

compile "org.grails.plugins:hibernate5"

Add the following hibernate-core dependency:

compile "org.hibernate:hibernate-core:5.0.7.Final"

Change the hibernate-ehcache dependency to the 5.0.7.Final version.

compile "org.hibernate:hibernate-ehcache:5.0.7.Final"
