Error when starting the Springboot examples

ofaklintra · July 10, 2018, 9:43am

I am trying out the Springboot examples in the 6.3.1 documentation. In the pom I have just only included the flowable-spring-boot-starter artifact. The program only runs issues SpringApplication.run

But when I start my application with Oracle JDK 1.8.144 I get the following error stack trace:

00:21:00.349 [main] ERROR org.springframework.boot.SpringApplication - Application run failed

In my pom.xml I have

<properties>
    <flowable.version>6.3.1</flowable.version>
</properties>
<dependencies>
<dependency>
    <groupId>org.flowable</groupId>
    <artifactId>flowable-spring-boot-starter</artifactId>
    <version>${flowable.version}</version>
</dependency>

My code does not do anything other that start the program

@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

I start the application with Oracle JDK 1.8.144

filiphr · July 10, 2018, 10:49am

Which Spring Boot version are you using?

It seems like there is a mix of Spring 4 and Spring 5 in there.

Can you also give us the output of mvn dependency:tree please?

Seems that there is some leak of Spring 4. Can you please show us your entire pom.xml? I think that if you add the spring boot as a parent the problem will go away

ofaklintra · July 10, 2018, 6:53pm

I gave no parent in the pom. Which spring boot verion should I add?
.

filiphr · July 10, 2018, 8:22pm

You should add the latest Spring Boot (2.0.3.RELEASE)

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.3.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

You can have a look at this example.

ofaklintra · July 11, 2018, 8:31am

Thank you. That worked.

But maybe the documentation could be clearer in section 5.7.2 where it says about adding the flowable-spring-boot-starter artifact to the pom:

That’s all that’s needed. This dependency will transitively add the correct Flowable and Spring dependencies to the classpath. You can now write the Spring Boot application:

filiphr · July 12, 2018, 6:37am

You are right, maybe we need to make that part a bit more clearer. Currently it assumes that a person know about Spring Boot and it’s conventions (to use a parent from Spring Boot) and adding the starter is adding to what start.spring.io would generate.

If you are up for it you could provide a PR (Pull Request) with a clarification that would make the most sense to you. We would gladly accept it

ofaklintra · July 13, 2018, 9:05pm

Thank you.

I have created a PR

filiphr · July 13, 2018, 9:47pm

That’s great. We’ve merged your PR already. Thanks for the contribution. Yiu are right it’s much clearer now

@raja27ravi,

It looks like you are trying to use spring boot auto configure version 1.4.7 with spring boot 2.2.4
