Gradle Spring Boot - spring jar versions are not automatically picked up - gradle

Question

I am trying out a simple gradle spring boot application as per the below URL
https://spring.io/guides/gs/spring-boot/
This is my build.gradle file
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
jar {
baseName = 'my-jar'
version = '1.0.0'
}
dependencies {
compile "org.springframework.boot:spring-boot-starter-web"
testCompile "junit:junit"
}
I am using a local artifactory and my init.gradle has the buildscript configuration which is below
buildscript {
repositories {
maven {
url 'http://mylocalartifactory:8081/'
}
}
dependencies { classpath "org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE" }
}
I get the below error when i try to run gradlew build
What went wrong:
Could not resolve all dependencies for configuration ':compileClasspath'.
> Could not find org.springframework.boot:spring-boot-starter-web:.
Looks like the version is not getting applied for the dependency.
What I understand is that the version will be defaulted by the spring-boot plugin .
Am I missing something ?
It works fine if I mention the version number in the dependency
dependencies {
compile "org.springframework.boot:spring-boot-starter-web:1.5.2.RELEASE"
testCompile "junit:junit"
}
Though I can make it work , it beats the purpose of using spring boot if I need to manually specify the spring version jar dependency .
Kindly revert back if you see any issue in my build.gradle or init.gradle
