Patching a Maven library with your custom class.

Sometimes you use a library that has a bug. Or maybe it doesn’t has a bug but you want to change something. Of course if it is an open source you can get the sources… build them … with your change and so on. However this first takes a lot of time and second you need the sources.What you usually want .. is to just replace one class.. or few classes with something custom… maybe add a line .. or remove a line and so on. Yesterday… I had an issue with jboss-logging. The version I was using was 3.2.0Beta1 and it turns out that using this version and log4j2 2.0 final basically meant that no log is send to log4j2. The reason was a null pointer exception that was catched in jboss logging class called Log4j2Logger. The bug I submitted is here https://issues.jboss.org/browse/JBLOGGING-107 and it was fixed at the same day. However I will use it as an example since I didn’t knew when this will be fixed.. and I didn’t want to wait till it is fixed.So I was thinking what I want.. to take the jboss-logging  jar  and replace the file called Log4j2Logger. Basically as you can see in the bug I wanted to replace line 54 to be :instead of : this.logger.log(null, loggerClassName, translatedLevel,parameters == null || parameters.length == 0 ? this.messageFactory.newMessage(message) :this.messageFactory.newMessage(String.valueOf(message), parameters),thrown); to become : this.logger.log(translatedLevel, parameters == null || parameters.length == 0 ? this.messageFactory.newMessage(message) : this.messageFactory.newMessage(String.valueOf(message), parameters), And that’s it. Of course I didn’t wanted to do this manually with zip but to use maven as well. So what I did: 1)...
