Grails 3 - Gradle dependecies Mysql Connector - mysql

Question

I have set up a grails app using grails 3.0.9
Now I want to add the mysql connector to bring up an connection to a mysql database.
Therefore I have added an entry to my build.gradle, but the connector is not fetched by gradle.
buildscript {
ext {
grailsVersion = project.grailsVersion
}
repositories {
mavenLocal()
maven { url "https://repo.grails.org/grails/core" }
}
dependencies {
classpath "org.grails:grails-gradle-plugin:$grailsVersion"
classpath "com.bertramlabs.plugins:asset-pipeline-gradle:2.5.0"
classpath "org.grails.plugins:hibernate:4.3.10.5"
classpath "mysql:mysql-connector-java:5.1.37"
}
}
plugins {
id "io.spring.dependency-management" version "0.5.2.RELEASE"
}
version "0.1"
group "nexttext"
apply plugin: "spring-boot"
apply plugin: "war"
apply plugin: "asset-pipeline"
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: "org.grails.grails-web"
apply plugin: "org.grails.grails-gsp"
ext {
grailsVersion = project.grailsVersion
gradleWrapperVersion = project.gradleWrapperVersion
}
assets {
minifyJs = true
minifyCss = true
}
repositories {
mavenLocal()
maven { url "https://repo.grails.org/grails/core" }
}
dependencyManagement {
imports {
mavenBom "org.grails:grails-bom:$grailsVersion"
}
applyMavenExclusions false
}
dependencies {
compile "org.springframework.boot:spring-boot-starter-logging"
compile "org.springframework.boot:spring-boot-starter-actuator"
compile "org.springframework.boot:spring-boot-autoconfigure"
compile "org.springframework.boot:spring-boot-starter-tomcat"
compile "org.grails:grails-dependencies"
compile "org.grails:grails-web-boot"
compile "org.grails.plugins:hibernate"
compile "org.grails.plugins:cache"
compile "org.hibernate:hibernate-ehcache"
compile "org.grails.plugins:scaffolding"
runtime "org.grails.plugins:asset-pipeline"
testCompile "org.grails:grails-plugin-testing"
testCompile "org.grails.plugins:geb"
// Note: It is recommended to update to a more robust driver (Chrome, Firefox etc.)
testRuntime 'org.seleniumhq.selenium:selenium-htmlunit-driver:2.44.0'
console "org.grails:grails-console"
}
task wrapper(type: Wrapper) {
gradleVersion = gradleWrapperVersion
}
Don't know what I am doing wrong but I get an ClassNotFoundException.

Answer 1

Add runtime "mysql:mysql-connector-java:5.1.37" to your dependencies (Right under runtime "org.grails.plugins:asset-pipeline"). Then compile it. That should do the trick.
In my Grails 3 project I don't have a classpath to the connector, so I think it is save to remove it there.
Also don't forget to add these lines to your application.yml under your dataSource:
driverClassName: com.mysql.jdbc.Driver
dialect: org.hibernate.dialect.MySQL5InnoDBDialect

Answer 2

Adding a local gradle installation to Intellij seems to solve the problem. I think that the included gradle-wrapper caused the trouble.
So downloading gradle 2.8 and setting it to use in Settings -> Build... -> Build Tools -> Gradle solved the problem.
Now the mysql connector is showing up under External Libraries
Gradle: mysql:mysql-connector-java:5.1.37
