I am new on Mule and Anypoint Studio and want to deploy a project. When I run it I get exceptions that might get caused by a jar dependency called wrapper for Mapping the java classes that says could not be found, how do I have to install this dependency? And if it is not the dependency then how to fix it? I don't know what to do at this point so I appreciate any answer.
I get the following exceptions when I try to run and compile the project:
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [net.inspira.api.transformers.json.ObjectToJsonMapper] for bean with name 'JsonMapper' defined in class path resource [spring/config-beans.xml]; nested exception is org.mule.runtime.module.artifact.api.classloader.exception.CompositeClassNotFoundException: Cannot load class 'net.inspira.api.transformers.json.ObjectToJsonMapper': [

The error is related to the class net.inspira.api.transformers.json.ObjectToJsonMapper. This class seems to be coming from artifact net.inspira.api:api-transformers:2.0.0. Since a quick search in Maven Central founds nothing related to that, I'll assume it is a proprietary library that your company uses. You would need to ask inside where it comes and how to install it.
Having said that, if there was no Maven error at built time, the dependency has been accessible to the build and the issue may be that the application can not see it because of Mule 4 classloader isolation. Try adding a Shared Library entry to the pom to make it visible. Example:
<sharedLibrary>
<groupId>net.inspira.api</groupId>
<artifactId>api-transformers</artifactId>
</sharedLibrary>
Put it with the other similar entries.
As a side note, this application seems to have been migrated from Mule 3 using the Mule Migration Assistant tool. Such migrations are not fully automated and required developers familiar with Mule 3 and Mule 4 to complete them. If you are new to Mule and the migration is not complete it may be extra hard for you to make it work.
