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

I ran into this because a JAR packed with the Shade plugin generated both the file and directory META-INF\version\9.

By excluding these files the JAR could be run again. The following is the configuration section for the maven-shade-plugin.

                
      
        
          *:*
          
            META-INF/*.SF
            META-INF/*.DSA
            META-INF/*.RSA
            META-INF/versions/9
            META-INF/versions/9/*
