Expected behavior

Azure function which uses a class from any dependent jar (which in this case is azure-storage) fails to execute after starting it locally using mvn azure-functions:run

Actual behavior

While starting the azure function the dependent jars loaded in the lib folder (target/azure-functions/<function-name>/lib/) by mvn azure-functions:package should be added to the functions classpath. This doesn’t seem to be happening, and failing to find the dependency makes the function hang indefinitely at the place where a class from a dependent jar is referenced.

As per the closing comment on #86, this should have work, and was suggested not to generate a fat-jar using the maven-shade-plugin

Steps to reproduce the problem

• Generate a azure function using the documented archtype mvn archetype:generate -DarchetypeGroupId=com.microsoft.azure -DarchetypeArtifactId=azure-functions-archetype -DarchetypeVersion=1.8
• Add a external dependency to the POM
• Reference a class from the dependent JAR in the Function.java file generated by the archtype
• Package and run the function using mvn azure-functions:package & mvn azure-functions:run
• Call the function using HTTP GET
• The function fails to respond

@jdneo yes it was azure-functions-core-tools. After the upgrade, it worked as expected.

@lovababu Thanks for your report, I tried the same pom configuration in an demo project and it seems that all the dependencies has been copied to lib of staging folder correctly. Could you please help share the output of maven package?
