Some aspects of system implementation, such as logging, error handling, standards enforcement and feature variations are notoriously difficult to implement in a modular way. The result is that code is tangled across a system and leads to quality, productivity and maintenance problems. Aspect Oriented Software Development enables the clean modularization of these crosscutting concerns. The AspectJ Development Tools (AJDT) project provides Eclipse platform based tool support for AOSD with AspectJ. Our goal is to deliver a user experience that is consistent with the Java Development Tools (JDT) when working with AspectJ projects and resources.

News and Releases

  • Finally updated the downloads page so it is obvious what the update site is for 4.7 - no guesswork required. AspectJ 9 enabled AJDT dev build are also available for Eclipse 4.7. Regular 4.7 builds include AspectJ 1.8 currently, this will likely switch to AspectJ 9 only when AspectJ 9 is released (currently at RC1).
