You want to compile your AspectJ project using Eclipse.
Download and install the AspectJ Development Tools (AJDT) plug-in into Eclipse.
AspectJ is run under the same open source collective as the Eclipse project and provides the most advanced AspectJ plug-in for an IDE. The AspectJ Eclipse plug-in can be downloaded by following the instructions available at http://www.eclipse.org/ajdt.
It’s a good rule of thumb to download the latest version of AspectJ, the corresponding latest version of the AJDT, and then download the supported version of Eclipse just in case the Eclipse tool is a step or so ahead of the AspectJ development. If you are ever confused by the options available, there is a compatibility table available on the AJDT downloads page to point you in the right direction.
To check that the plug-in has been correctly installed, click on File→ New→ Project... on the Eclipse menu bar. When the New Project dialog appears, the AspectJ project option should be available, as shown in Figure 2-1.
