4.14.5 is work in progress. Please use https://github.com/apache/camel-karavan/releases

Thanks @mgubaidullin, Still i am facing same issue. I have attached full logs

>  git checkout 4.14.2                                  
Note: switching to '4.14.2'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false


HEAD is now at 1901f4cc Default credentials

[arockiaraj1994]

I found the cause

This is because of

public final class KaravanGenerator {

    public static void main(String[] args) throws Exception {
        String rootPath = args.length > 0 ? args[0] : "";
        
        ......
    }

}

Fix 1: Compile level
Pass current path as part of building generator.

mvn clean compile exec:java -Dexec.mainClass="org.apache.camel.karavan.generator.KaravanGenerator" -Dexec.args="." -f karavan-generator

Fix 2: Code level

public final class KaravanGenerator {

    public static void main(String[] args) throws Exception {
        String rootPath = args.length > 0 ? args[0] : ".";
        
        ......
    }

}
