Errors while deploying starter Spring-Boot

Anuj28282828 · September 19, 2019, 1:12pm

Hi All,

I am getting this error while deploying a simple Spring-Boot camunda-spring-boot-starter-rest project.
Any ideas?

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘createRestConfig’ defined in class path resource [org/camunda/bpm/spring/boot/starter/rest/CamundaBpmRestJerseyAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/camunda/bpm/engine/rest/impl/CamundaRestResources

Also, I am continuously getting this error :

`Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Fri Sep 20 10:51:37 IST 2019

There was an unexpected error (type=Not Found, status=404).

No message available`

Yana · September 20, 2019, 6:00am

Could you please share your pom.xml and which url do you try to access?

Anuj28282828 · September 20, 2019, 6:09am

conditions_report.txt (99.9 KB)

Here are some positive/negative matches from CONDITIONS EVALUATION REPORT in DEBUG mode.
My application is up and running fine but I am not able to hit the rest calls

Anuj28282828 · September 20, 2019, 6:09am

I am running it on Gradle.

Anuj28282828 · September 20, 2019, 6:18am

Some JARs are :

camunda-engine-rest-core-7.12.0-alpha3
camunda-bpm-spring-boot-starter-rest-2.0.0
java-uuid-generator-3.1.3
camunda-bpmn-model-7.10.0
camunda-bpm-spring-boot-starter-3.2.0
camunda-external-task-client-1.2.2

Attached are my dependencies

gradle_deps.txt (2.3 KB)

Yana · September 20, 2019, 6:32am

you have inconsistent versions for the engine, starter, model, and client,
pick the engine version
for example 7.11.0 and then follow the Version Compatibility matrixes (1), (2) to choose the other versions:

camunda-bpmn-model and camunda-engine-rest-core should match as well: 7.11.0
camunda-bpm-spring-boot-starter-rest and camunda-bpm-spring-boot-starter should match: 3.2.0
spring-boot: 2.1.x
camunda-external-task-client: 1.2.2

(1): https://docs.camunda.org/manual/7.11/user-guide/spring-boot-integration/version-compatibility/
(2): https://docs.camunda.org/manual/7.11/user-guide/ext-client/compatibility-matrix/

Anuj28282828 · September 20, 2019, 6:42am

Where do I get to know what are the versions available for camunda-engine-rest-core/camunda-bpmn-model/camunda-bpm-spring-boot-starter-rest/camunda-bpm-spring-boot-starter?

Yana · September 20, 2019, 6:44am

for example here:

I am getting this error now :

And I don’t see a JAR to be downloaded for this.

Are you using maven or Gradle? You can do maven or Gradle refresh dependencies, which will pull the jars if not available in the classpath

Anuj28282828 · September 21, 2019, 7:29am

Hey Aravindh/Yana - This class comes from a WAR file. Why is this really required for setting up a simple Spring Boot application? How can you import a war file?

Also, this is how my gradle dependencies look like right now :
Do you see any issues here now?

And below is my spring config JARs :

Anuj28282828 · September 21, 2019, 5:08pm

after importing jaxrs2 JAR the above issue was resolved but for the URL, I am still getting 404 Not Found.

The URL at my side which are down are :
http://localhost:9081/engine-rest/task
http://localhost:9081/rest/task

However the actuator URL is up and running for me - http://localhost:9081/actuator/health

Also I am getting below error :

@Yana, @Niall, @aravindhrs - Can you please help me with this?

Even after below success message in logs, the engine-rest API still says 404 not found.

Some log snippet :

Hello, @Anuj28282828.

Try this URL http://localhost:9081/rest/engine/

Anuj28282828 · October 11, 2019, 2:46pm

@Beagler - For your consideration

Beagler · October 11, 2019, 3:04pm

For spring apps the base URL for rest is http://localhost:8080/rest.

Beagler · October 11, 2019, 3:06pm

Here is a sample pom.xml that is generated from the archetype. Camunda provides Maven archetypes to help prevent errors in version mismatchespom.xml (5.5 KB)

Beagler · October 11, 2019, 3:08pm

Have a look at the rest dependency

<dependency>
      <groupId>org.camunda.bpm.springboot</groupId>
      <artifactId>camunda-bpm-spring-boot-starter-rest</artifactId>
      <version>${camundaSpringBoot.version}</version>
</dependency>
