The error shows that the version is not known: Could not find artifact org.activiti:activiti-spring-boot-starter:pom:unknown.

You could specify a version like so:

<dependency>
   <groupId>org.activiti</groupId>
   <artifactId>activiti-spring-boot-starter</artifactId>
   <version>7.1.0.M6</version>
</dependency>

Which I found here. However are you sure you have the right dependency? Looking at this guide the dependency shown is:

<dependency>
  <groupId>org.activiti</groupId>
  <artifactId>spring-boot-starter-basic</artifactId>
  <version>${activiti.version}</version>
</dependency>

The difference being activiti-spring-boot-starter ->spring-boot-starter-basic
