I have referred to this Youtube video for Camunda Get Started: Video.

Here, I was able to add the JavaDelegate Interface while creating a new Java Class.

In the video, Niall has used Widlfly, and while deploying, the process is entirely different compared to Camunda Run Open source(I am working on)

I am unable to create a JavaDelegate class in Camunda Open Source.

Here is an example of a JavaDelegate

https://github.com/mentiflectax/minimal-crypto-exchange/blob/0.1/process-engine/src/main/java/com/dpisarenko/minimalcryptoexchange/delegates/ApproveUsdtTransfer.java

Crucial part #1:

`import org.camunda.bpm.engine.delegate.JavaDelegate;`

Crucial part #2:

```

@Component("ApproveUsdtTransfer")

public class ApproveUsdtTransfer implements JavaDelegate {

...

@Override

    public void execute(final DelegateExecution delEx) throws Exception {

// Do whatever you want to do here
}

...

}
```

Can you create a class like this? If not, why not?

На первый взгляд узнать состояние задачи можно с помощью вот этого запроса:

https://docs.camunda.org/manual/7.16/reference/rest/task/get/

Если я правильно понимаю, то в ответе приходят данные всех незавершенных задач.

Управлять задачей можно с помощью вот этих запросов:

1. Завершить: https://docs.camunda.org/manual/7.16/reference/rest/task/post-complete/
2. Назначить пользователю: https://docs.camunda.org/manual/7.16/reference/rest/task/post-claim/
3. Снять назначение: https://docs.camunda.org/manual/7.16/reference/rest/task/post-unclaim/

Благодарю Дмитрий! Хотелось бы не через редирект на урл TaskResource или так тоже можно? . А уже на бэке засетить нужное значение переменной.

просто загнать переменную в вариаблес и выполнить код VariableMap taskVariables = formService.submitTaskFormWithVariablesInReturn(taskId, variables, false);

Для каждого запроса REST API есть соотв. вызов Java API.

Конкретно здесь я бы посмотрел на org.camunda.bpm.engine.rest.sub.task.impl.TaskResourceImpl#submit:

  @Override
  public Response submit(CompleteTaskDto dto) {
    FormService formService = engine.getFormService();

    try {
      VariableMap variables = VariableValueDto.toMap(dto.getVariables(), engine, objectMapper);
      if (dto.isWithVariablesInReturn()) {
        VariableMap taskVariables = formService.submitTaskFormWithVariablesInReturn(taskId, variables, false);
    
    ...

    } 
  
  ...

  }

Как я понимаю, этот кот код, который выполняется при REST-запросе

package org.camunda.bpm.engine.rest.sub.task;

...

public interface TaskResource {

...

  @POST
  @Path("/submit-form")
  @Consumes(MediaType.APPLICATION_JSON)
  @Produces(MediaType.APPLICATION_JSON)
  Response submit(CompleteTaskDto dto);

...

Hi, as I was following the Get Started Guide --> I created the POM.xml File:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>

<groupId>org.camunda.bpm.getstarted</groupId>
<artifactId>charge-card-worker</artifactId>
<version>0.0.1-SNAPSHOT</version>

<properties>
<camunda.external-task-client.version>7.16.0</camunda.external-task-client.version>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>

<dependencies>
<dependency>
<groupId>org.camunda.bpm</groupId>
<artifactId>camunda-external-task-client</artifactId>
<version>${camunda.external-task-client.version}</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.6.1</version>
</dependency>
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.1</version>
</dependency>
</dependencies>
</project>

In this POM.xml file, in Properties tag:

<properties>
<camunda.external-task-client.version>7.16.0</camunda.external-task-client.version>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>

When I add <camunda.external-task-client>, I cannot add Java Class with JavaDelegate Interface.

If I follow the Springboot tutorial and create a project using "start.camunda.com", I can create a class with JavaDelegate Interface.
I compared the two POM.xml files from both the projects; I tried to copy-paste, but again I could not get the desired output.
Is it possible to create a class using JavaDelegate Interface in Open Source BPM -- Get Started Guide?

What dependencies am I missing?

Dmitrii Pisarenko in Camunda BPM Group

In order to use `JavaDelegate`s you don't need any additional dependencies.

So, I would remove

<dependency>
   <groupId>org.camunda.bpm</groupId>
   <artifactId>camunda-external-task-client</artifactId>
   <version>${camunda.external-task-client.version}</version>
  </dependency>

Also, please create a GitHub project without any sensitive information (like company names) and post the link here.

Then, it will be much easier to tell how to fix your issues.
