This error means that maven shade plugin has modified one of your dependencies hence the signature for those libraries are invalid.

remove the signature files is a work around and a solution depending on your use case. For me it is a bad practice so I ended up replacing the maven shade plugin for Apache Maven Assembly Plugin to create the jar with the dependencies and seems to work https://maven.apache.org/plugins/maven-assembly-plugin/

example:

        
            org.apache.maven.plugins
            maven-assembly-plugin
            
                
                    package
                    
                        single
                    
                    
                        
                            
                                
                                    your.class.with.main.method
                                
                            
                        
                        
                            jar-with-dependencies
                        
                    
                
            
        

build your jar with dependencies included:

mvn package
