Starting with version 1.6.2, AJDT will be shipped with the JDT weaving plugin. This plugin uses Equinox Aspects to weave into JDT (more specifically, the org.eclipse.jdt.core, org.eclipse.jdt.ui, and org.eclipse.jdt.debug.core plugins).

This provides an opportunity for deep integration with Eclipse in ways that were not possible before. This release introduces the following features:

  • ITD-aware content assist
  • ITD-aware type hierarchies
  • ITD-aware reconciling/eager parsing
  • Ability to search for aspect elements using standard Java search and Open Java type

For information on how to use the JDT weaving plugin to provide deep integration with plugins and editors for other Java-like languages, see JDT weaving implementation.

Installation

Weaving AJDT is only available for Eclipse 3.4. Use the update site:

http://download.eclipse.org/tools/ajdt/34/dev/weaving

Installing from this update site will automatically install Equinox Aspects from a separate update site. Additionally, the install will update your config.ini file to allow the weaving service to be enabled at startup.

Due to Bug 257178, it is currently only possible to install Weaving AJDT in the same directory that Eclipse itself is installed in.


Runtime

To see if the JDT Weaving plugin is properly configured:

  1. Create a new aspect in an AspectJ project and save.
  2. Open the Open Types dialog (Ctrl-Shift-t on Windows).
  3. Type the name of the new aspect.
  4. If it appears, rejoice! The JDT weaving plugin is now working.

Uninstalling

Uninstall Weaving AJDT in the same way you uninstall any other Eclipse feature:

Help -> Software Updates -> Installed Software

Select AJDT, and click Uninstall.... This will also uninstall Equinox Aspects and reset your config.ini to its previous state.


Running Weaving AJDT without JDT Weaving

It is possible to disable the weaving service and still run AJDT 1.6.2. However, all the advanced features will be disabled.

In the file eclipse/configuration/config.ini, delete the line that looks something like this:

osgi.framework.extensions=org.eclipse.equinox.weaving.hook

For now, there is no automatic way of doing this. In the future, there will be an option in the preferences page for this.
