Maven shade jar throw exception

Question

I have the following Exception:

Exception in thread \"main\" java.lang.SecurityException: no manifiest section for signature file entry javax

Answer 1

The SecurityException comes up because one of your dependencies is a signed jar. As the shade plugin is repacking this jar, it gets invalid. -> SecurityException at launch

To solve the problem, you have to unsign the dependency jars while repacking them. This can be done by simply not repacking the files that make the jar signed, using a filter:

    org.apache.maven.plugins
    maven-shade-plugin
    1.5
    
        
            stand-alone
            package
            
                shade
            
            
                true
                stand-alone
                
                    
                        
                        *:*
                        
                            META-INF/*.SF
                            META-INF/*.RSA
                            META-INF/*.INF
