Adding the jts and spatial4j dependencies did the trick for me:
<dependency>
<groupId>com.vividsolutions</groupId>
<artifactId>jts</artifactId>
<version>1.13</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.locationtech.spatial4j</groupId>
<artifactId>spatial4j</artifactId>
<version>0.6</version>
<scope>test</scope>
</dependency>
