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.

Thanks camunda-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
https://docs.camunda.org/manual/7.10/user-guide/spring-boot-integration/version-compatibility/

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:

But the problem only happened when starting the camunda project through STS boot dashboard.

Are you using any JVM args? can you provide your runtime jvm args for application startup parameters?

Hi aravindhrs,

There is none. You can refer to the attached screenshot on both the error and also the command prompt. The command prompt case will start successfully.

The complete error is as follow:

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

FYI, i also tested with spring boot version 2.1.1.RELEASE, camunda spring boot starter 3.2.0, camunda version to 7.10.0 together with adopt open JDK 11, the same error happened as below:

Error: Could not find or load main class See.m2\repository\org\camunda\bpm\springboot\camunda-bpm-spring-boot-starter\3.2.0\camunda-bpm-spring-boot-starter-3.2.0.jar;C:\Users\Darren

Try build your application. Make sure the scope is set to compile.

And also share your pom.xml/build.gradle file.

Classloader is not able to find the class in the classpath. How did you added your dependencies to the project?

For dependencies, you must specify maven repo.
