* Where:
Build file 'C:\Users\Adib Samoon\Desktop\Projects\module-ballerinax-slack\ballerina\build.gradle' line: 22

* What went wrong:
Plugin [id: 'io.ballerina.plugin', version: '2.2.4'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
