Local runner: Invalid signature file digest for Manifest main attributes

[YannPerthuis]

Describe the bug
Hi, I'm currently working with the pulsar functions local runner and I got this following error when I run my application. It throws when I instantiate the FunctionConfig class like the example in the doc.

Error:

Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

To Reproduce
Steps to reproduce the behavior:

1. Create gradle project
2. Add following dependencies to your build.gradle :

dependencies { 
    implementation group: 'org.apache.pulsar', name: 'pulsar-functions-api', version: '2.7.1'
    implementation group: 'org.apache.pulsar', name: 'pulsar-functions-local-runner', version: '2.7.1'
}

3. Copy paste the ExclamationFunction class from the Debug with localrun mode example
4. Run the main method

Expected behavior
Be able to run the function on the local runner without getting this problem.

Desktop:

• OS: macOs v11.2.3
• Gradle: v7.0
• Java: v8
• Pulsar: v2.7.1

I am seeing this same issue on version 2.9.1 of the local runner, but works on 2.6.4
