Open Source Mac Build Tools

ProGuard has moved to Github now: https://github.com/Guardsquare/proguard ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. ProGuard is useful for making code more compact and more efficient, on the desktop, on tablets, on smartphones, and on embedded devices. It also makes code more difficult to reverse engineer.

JavaGuard is a general purpose bytecode obfuscator, designed to fit effortlessly into your regular build and testing process, providing peace of mind that your valuable Java code is more secure against decompilation and other forms of reverse engineering

The project provides a set of Ant tasks for developing J2ME/MIDP applications based on the J2ME Wireless Toolkit. The new tasks allow for compilation, preverification, packaging, and obfuscation of a MIDlet suite as well as for making a PalmOS PRC file.

Jymini is a JavaScript minifier and obfuscator. While there are several of these out there, I couldn't find one that did exactly what I needed. This program is very flexible and has features that others don't.

Yet another Java obfuscation tool. This one has a bit of a different twist, in that it can obfuscate native methods by generating a .h file which #defines the original method names to the obfuscated ones. Built with Apache BCEL.

Obclipse manage the obfuscation of an ready build eclipse product. It collects the necessary information of a product, configure a third party obfuscator, obfuscate the product and fixes the textual files of the plugins by the obfuscated class names.

obfuscate4e is an Eclipse feature to obfuscate plugins during their export. This feature provides an integrated proguard obfuscator, other obfuscators might be added as plugins. The project moved to http://code.google.com/p/obfuscate4e/
