Come escludere determinate dipendenze Jar quando si utilizza Maven per Jar Assembly

Question

Ci sono una manciata di domande apparentemente molto simili su StackOverflow, ma ho difficoltà a trovare qualcosa che funzioni.

Per ora, sto cercando di rimuovere log4j dal Jar costruito.

Anche se sono nuovo di Maven, e sono sicuro di aver sbagliato tutto, ecco quello che sto provando.

Tuttavia, il vaso risultante finisce con l'/ org/apache/log4j/classi inclusi.

Come sbarazzarsi di loro?

Grazie!

Puoi provare a dichiarare la dipendenza come un ambito fornito, ad es.

<dependency> 
     <groupId>log4j</groupId> 
     <artifactId>log4j</artifactId> 
     <version>1.2.17</version> 
     <scope>provided</scope> 
    </dependency>
