The JHipster Mini-Book The JHipster Mini-Book is a guide to getting started with hip technologies today: Angular, Bootstrap, and Spring Boot. All of these frameworks are wrapped up in an easy-to-use project called JHipster.

This book shows you how to build an app with JHipster, and guides you through the plethora of tools, techniques and options you can use. Furthermore, it explains the UI and API building blocks so you understand the underpinnings of your great application.

Maven 2 hates Commons Logging

It's true that most people hate commons-logging, but Maven 2 hates it even more. There are many open source projects that use this library, so you're likely to depend on it when you never intended to. Of course, this is Maven 2's transitive dependencies fault - but currently there's no option to turn transitivity off. I tried changing to SLF4J, but that causes some Maven plugins to fail.

Since the Maven team refuses to fix this (even though it's an *obvious* exception to their rule about not changing anything), I've fixed it myself. The AppFuse repo has a fixed version of commons-logging's pom.xml. To get the fixed version of commons-logging, delete it from your local repo, then add AppFuse's repository to your pom.xml:


Since the burden of this issue clearly rests upon the shoulders of the commons-logging developers - can we please get a new release with a fixed pom? Pretty please?

Update: I tried to get slf4j to work again today. While I succeeded, I found a critical bug. The bug is that log messages don't print out the method name, just debug(), info() or whatever from your classes. It's possible to fix this by using slf4j instead of clogging. However, that won't help you get method names printed when cranking up the logging for 3rd party libraries like Spring and Hibernate. Since this won't be fixed, it seems better to stick with commons-logging. I doubt I'd have any luck getting all the libraries that AppFuse uses to move away from commons-logging.
