The constructor TaskLaunchRequest(String, List<String>, null, null) is undefined - Spring Cloud Task - spring

Question

I am developing a code for the Spring Cloud with Spring Boot. In this example, I am working in Spring Cloud Tasks. I was using Spring Boot <version>1.4.1.RELEASE</version> then below code was working fine. When I updated <version>2.0.4.RELEASE</version> then I am getting below error.
The constructor TaskLaunchRequest(String, List, null, null) is undefined
TaskProcessor.java
#Component
#EnableBinding(Source.class)
public class TaskProcessor {
#Autowired
private Source source;
public void publishRequest(String payload) {
//maven://[groupid]:[artifactid]:jar:[version]
//String url = "maven://pluralsight.demo:pluralsight-springcloud-m3-task:jar:0.0.1-SNAPSHOT";
String url = "maven://pluralsight.demo:springcloud-m3-tasksink:jar:1.0";
List<String> input = new ArrayList<String>(Arrays.asList(payload.split(",")));
TaskLaunchRequest request = new TaskLaunchRequest(url, input, null, null);
System.out.println("created task launch request ...");
GenericMessage<TaskLaunchRequest> message = new GenericMessage<>(request);
this.source.output().send(message);
}
}

I had the same problem and after the following modifications in the pom file it works.
replace your:
<spring-cloud.version>Finchley.SR1</spring-cloud.version>
with:
<spring-cloud.version>Brixton.SR6</spring-cloud.version>
replace your:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-task</artifactId>
</dependency>
with:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-task-starter</artifactId>
<version>1.0.1.RELEASE</version>
</dependency>
