Please dont create Jira issue for something, what is clearly your error and not a bug in Apache Camel. We are active on mailing list, zulip and StackOverflow and ready to help you. Jira is here for reporting bugs.

First read this - [https://camel.apache.org/manual/latest/support.html]
{quote}Please refrain from immediately opening a ticket in the issue tracker unless you are certain it’s a problem in the Camel software. If you are in doubt, we appreciate asking the [mailing list|https://camel.apache.org/manual/latest/mailing-lists.html], or [Chat room|https://camel.zulipchat.com/] first.

And then look at my answer to your question on SO - [https://stackoverflow.com/a/64018354/8576169]
{quote}Shadowing jars is quite magic, because you need to handle duplicate entries somehow. In Apache Camel there are many {{META-INF}} service files, which are getting overwritten with your simple {{jar}} approach. Use {{com.github.johnrengelman.shadow}} which is allowing you to customize merging process.
{code:java}
shadowJar {
    mergeServiceFiles() // Tell plugin to merge duplicate service files
    manifest {
        attributes 'Main-Class': 'com.eip.App'
    }
}
apply plugin: 'com.github.johnrengelman.shadow'
{code}
