Camunda web app spring boot project start failed


Java version: JDK 11
Spring boot version: 2.0.2.RELEASE
Camunda version: 7.9.0
Camunda spring boot version: 3.0.0

When i startup my camunda spring boot project, it encounters the following error:

Error: Could not find or load main class See.m2\repository\org\camunda\bpm\springboot\camunda-bpm-spring-boot-starter\3.0.0\camunda-bpm-spring-boot-starter-3.0.0.jar;C:\Users\Darren
Caused by: java.lang.ClassNotFoundException: See/m2\repository\org\camunda\bpm\springboot\camunda-bpm-spring-boot-starter\3/0/0\camunda-bpm-spring-boot-starter-3/0/0/jar;C:\Users\Darren

I have confirmed that camunda-bpm-spring-boot-starter-3.0.0.jar is inside my .m2 folder. Can help to look into this issue?

Attached here are the pom.xml for both camunda-bpm-service-v1 and customized-camunda-webapp-webjar-lib.

Please help.

Thankscamunda-bpm-service-v1.xml (3.5 KB)
customized-camunda-webapp-webjar-lib.xml (5.3 KB)


JDK 11 is not supported with camunda spring boot starter 3.0.0, you need to switch to 3.2.0, Camunda version 7.10, spring boot 2.1.1


Tested with JDK 10, camunda spring boot starter 3.0.0, Camunda version 7.9.0 and spring boot 2.0.2, same error too when startup in STS.


starter 3.0.0 works only with java <= 8. If you need 10 or 11, you will have to upgrade like Yana said.



I am trying out this tutorial with this jdk/runtime:

openjdk version “11.0.2” 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

When trying to build, it works fine. But when I run it, it fails. Could you please add the correct POM dependencies to run the example/s:


You will need spring Boot 2.1.1 , camunda 7.10 and starter 3.2 for Java 11


For version compatibility check this.


Thanks for pointing out on the version incompatibility. But the problem only happened when starting the camunda project through STS boot dashboard. If i use command prompt to start the spring boot project java -jar camunda-bpm-service-v1.jar, there is no issue in startup.
