You're getting this error because there is no jar artifact for spring-boot-starter-parent in maven central, since spring-boot-starter-parent uses pom packaging. The reason for that is because it's intended to be used as a parent pom:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.2.RELEASE</version>
</parent>
Alternatively, you can just import the managed dependencies if that is what you intended to do:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.2.RELEASE</version>
<scope>import</scope>
<type>pom</type>
</dependency>
</dependencies>
</dependencyManagement>
You can read more about importing dependencies in the Importing Dependencies section of the Introduction to the Dependency Mechanism article.
