Why should I update?

• Java 8 has reached EOL, so if we want to start using Java 11 it is important migrate to Grails 5 that uses Groovy 3.x and supports Java 11.

• Grails 4 will be discontinued at the end of 2023, if you have plans to continue using your application in production you need to keep your project updated.

• Grails 5 it’s the most recent version of the framework, so provides an easy way to update to futures versions.

Steps to upgrade to Grails 5

1. Update your gradle version in gradle/wrapper/gradle-wrapper.properties, Grails 5 is using Gradle 7.2 and later distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-bin.zip also you can run this command ./gradlew wrapper --gradle-version 7.2
   
   
2. Update your grailsVersion, gorm.version and groovyVersion in your gradle.properties
grailsVersion=5.2.0
groovyVersion=3.0.7
gorm.version=7.2.0
   
   
3. Update your views-gradle should be like this "org.grails.plugins:views-gradle:2.3.2"
   
   
4. In your build.gradle you need to use implementation instead of compile, providedRuntime instead of provided, runtimeOnly instead of runtime, testImplementation instead of testCompile
