I tried to configure my application (with embedded Camunda) to use Camunda with JSON as the default serialization format (using the SPIN plugin). I followed the steps described in the Configuring Spin Integration documentation.
Therefore I added the artifacts camunda-spin-core, camunda-spin-dataformat-json-jackson and camunda-engine-plugin-spin to my dependencies. As I understood these should be all additional dependencies I need.
Unfortunately I run into the following exception
Caused by: java.lang.ClassNotFoundException: com.jayway.jsonpath.spi.JsonProvider
at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[?:1.8.0_91]

at org.camunda.spin.DataFormats.registerProvider(DataFormats.java:152) ~[camunda-spin-core-1.3.0.jar:1.3.0]
I assume that a dependency is missing. If I replace camunda-spin-dataformat-json-jackson with camunda-spin-dataformat-all everything works fine.
I wonder if my assumption is right or if I did something wrong?

Hi @FrVaBe ,
have you configured the Sping Process Engine Plugin ?
Best,

If you mean this
/**
* Bean creation method for the Camunda SpinProcessEnginePlugin.
*
* @return the SpinProcessEnginePlugin bean
* @see <a href=
* "https://docs.camunda.org/manual/latest/user-guide/data-formats/configuring-spin-integration/#configuring-the-spin-process-engine-plugin">Configuring
* the Spin Process Engine Plugin</a>
*/
@Bean
SpinProcessEnginePlugin spinProcessEnginePlugin() {
return new SpinProcessEnginePlugin();
}
yes. It all works well just by replacing camunda-spin-dataformat-json-jackson with camunda-spin-dataformat-all.

I removed (only few) custom artifacts.
For some reason, you have json-path 2.2.0 on the classpath instead of 0.9.1 which is the version used in Spin 1.3.0 (see https://github.com/camunda/camunda-spin/blob/1.3.0/dataformat-json-jackson/pom.xml#L39-L49 ). From the log above alone I can’t tell you why that is the case, but you could investigate in that direction.

Thanks. Will have a look and will post the cause if found.

Found the cause. The 2.2.0 version ist declared by the Spring IO platform BOM that I also use in my pom to get a reliable set of spring module versions and artifacts.
I will go with the camunda-engine-dataformat-all artifact now because of the included and relocated version of json-path.
Thanks for your support.
