A version conflict results in a build failure. This strategy requires all version conflicts to be resolved explicitly in the build script. https://gradle.org/docs/current/userguide/dependency_management.html#sub:version_conflicts

build.gradle

apply plugin: 'java'

repositories {
    mavenLocal()
}

configurations.all {
    //TODO comment out to result in a build failure
    //resolutionStrategy.failOnVersionConflict()
}

dependencies {
    compile "org.springframework:spring-webmvc:3.2.4.RELEASE"
    compile "org.springframework.security:spring-security-web:3.1.4.RELEASE"
}
