AWS Lambda Java: Lambda was not able to unzip the file

Question

I\'m trying to use Java with AWS Lambda. I created a jar file with all dependencies (using maven-assembly-plugin). Upon uploading, I cannot call the lambda. I receive the error

Answer 1

maven-assemply-plugin needs to be told to output a zip, not a jar. (I didn't even know there was a difference!)

Add this to its configuration:

     org.apache.maven.plugins
     maven-assembly-plugin
     ...
     
         ...
         
            zip
