'Java azure function not deploying dependencies
My app has a few maven dependencies. I am able to run the app locally as expected.
When deployed via mvn clean package followed by mvn azure-functions:deploy, it gets deployed. But when accessed, the function throws an exception.
Though when I deploy it via the IntelliJ plugin, it works as expected. What could be going wrong here?

Solution 1:[1]
This looks like the culprit:https://github.com/Azure/azure-functions-java-worker/issues/381
This issue is only with Java8.
Setting the flag FUNCTIONS_WORKER_JAVA_LOAD_APP_LIBS to True fixed it in the Configuration tab. (you can check this to know on how to set it)
