Camel routes to resume/start Activiti task with variables - spring-boot

Question

I have setup spring boot with activiti and camel. I am trying to configure Camel routes to poll email to do the below. Some examples on the same would be really helpful:
Resume a activti task
Start a activiti task
For e.g. to resume a user task we need to pass something like the below to Acitviti Rest API which works fine
{"action" : "complete", "variables": [ {"name":"id, "value":1}, {"name":"outcome", "value":true} ]}
I started with the below for setting up Camel Routes, but not sure how to add variables that needs to be passed into activiti process:
#Component
public class MyCamelMailRouter extends RouteBuilder {
#Override
public void configure() throws Exception {
from("imaps://imap.server.com?username=myemail#example.com&password=xxxxxx&consumer.delay=60000"
+ "&searchTerm.subject=Approving&searchTerm.unseen=true")
.to("activiti:activationProcess:approval");
}
}
Here are my maven dependencies
<properties>
<activiti.version>5.22.0</activiti.version>
<activiti.rest.version>5.17.0</activiti.rest.version>

The above throws the below exception during spring boot startup, going by few references from various google searches revealed that I could direct to activiti using the notation I have used but as the error points it is not there by default. Any help would be greatly appreciated.

Answer 1

You need to add the JAR / maven dependency of the activiti-camel component. Its not from Apache Camel but from the Activiti project so look there what the dependency is named.
You can see that from the last stacktrace saying the component is not found.
