Error after removing scope.
I removed the scope. I am getting this error:Error occurred while running main from:
org.apache.camel.spring.Main java.lang.ClassNotFoundException:

Answer 1

Its a classpath issue, this class is not found org.apache.camel.spring.Main, which is from the camel-spring dependency. So you should remove the compile scope, eg just use
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-spring</artifactId>
<version>${camel.version}</version>
</dependency>

Answer 2

I got a similar error recently. Changing the target SDK to an OpenSDK got things working again.
