Is there a simple way to use a different Spring version? - spring

Question

I want to use latest Spring 4.1.x snapshot in my Spring Boot project.
Is there a simple way to override the version of all Spring dependencies, or should I include all required Spring dependencies with it's desired version manually?
Reason is I want experiment with Spring 4.1 #JsonView annotation in REST services.

Answer 1

If you're using Maven with spring-boot-starter-parent as the parent, you can override the spring.version property in your pom to change the version of Spring that you're using:
<properties>
<spring.version>4.1.0.BUILD-SNAPSHOT</spring.version>
</properties>
If you're using Gradle, you can achieve the same effect by using a resolution strategy to override the version of everything with the org.springframework group id:
configurations.all {
resolutionStrategy {
eachDependency {
if (it.requested.group == 'org.springframework') {
it.useVersion '4.1.0.BUILD-SNAPSHOT'
}
}
}
}

I once again needed this and previous block doesn't work anymore, causing already dependencies to be failed.
Anyway this works:
configurations.all {
resolutionStrategy {
eachDependency { DependencyResolveDetails details ->
if (details.requested.group == "org.springframework") {
details.useVersion "4.1.0.RC1"
}
}
}
}

Given that you're using Spring Boot, I'm guessing that you must be using either Maven or Gradle, but you don't say which. For Maven, you have a couple of things you might be able to do.
First, you could have a go at just forcing the Spring version in your pom.xml:
<properties>
<spring.version>4.1.0.BUILD-SNAPSHOT</spring.version>
</properties>
That ought to override the property which is defined in the spring-boot-dependencies project.
For more fine-grained control, use dependency management:
<dependencyManagement>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>4.1.0.BUILD-SNAPSHOT</version>
</dependency>
</dependencyManagement>
