How can I complete a task using the Java API? A mocked up example would be helpfull.

Hi @withnoe,

You can use the TaskService to complete a task by its taskId. Have a look at the docs:
https://docs.camunda.org/manual/7.14/reference/bpmn20/tasks/user-task/#completion

Thanks! I am new to Java so this may be incorrect. Below is what I have tried and am getting errors.

No signature of method: org.camunda.bpm.engine.impl.ProcessEngineImpl.call() is applicable for argument types: () values: []

def varNames = runtimeService.getVariables(it.executionId)
String requestId = varNames.requestId
String pidm = varNames.pidm
String taskId = ‘a76bb7f7-1220-11eb-b309-0800271e8913’
if (requestId != null && pidm != null) {
def advisorApprovalCheck = approvalMySqlService.advisorApprovalCheck(requestId, pidm)
if(advisorApprovalCheck != null) {
def advisorComplete = processEngine()
.setVariable (“advisorApproval”, advisorApprovalCheck.advisorDecision)
.complete(taskId)
}
}

Hi @withnoe

Can you take a look at the Style Guide? It’ll help you understand how to format code correctly and also help you create questions that are easy to understand and also easier to answer :slight_smile:

Hi @withnoe,
Where did you put that code? It is not valid Java code…Looks like Groovy. Did you put it into a script Task or a Listener? The service calls are wrong, you’ll need to get the needed services from the processEngine first, e.g. the RuntimeService to update a variable, the TaskService to complete a UserTask.

Probably it helps if you have a closer look to our docs describing how scripting works:
