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
