What's New in 4.24 (PDE)

Here are descriptions of some of the more interesting or significant changes made to the Plug-in Development Environment (PDE) for the 4.24 release of Eclipse. They are grouped into:

Dialogs, Wizards and Views

Event Spy added to PDE

The Event Spy allows to view the events sent using an IEventBroker and is now available via PDE, using the Spies menu or the Alt+Shift+F8 shortcut (on windows).

Start capturing events, and check the event's contents in the table. For instance, here the spy window has moved, and all the location events were caught.

Include requirements automatically when launching an application The Launch Configuration Wizard offers a new option in the Plug-ins tab to include required but missing plug-ins or features automatically while launching an Eclipse or Equinox application. By default this is enabled for Launch Configurations based on Features and disabled for those based on products, which reflects the previous behavior.

Missing plug-ins/features are only added to the launched application but not to the Launch Configuration. This allows to specify only the 'root' features/plug-ins you actually want in your application and to let Eclipse include only the minimal set of requirements in each launch. Consequently new dependencies don't have to be added to the Launch Configuration anymore.

Automatically include requirements in launch

Editors

Include requirements automatically when launching a product The Product Editor offers a new option in the Contents tab to include required but missing features or plug-ins automatically when launching the product from the IDE.

This controls if the corresponding option, which is described above, is activated or not for the Launch Configuration associated with the product launch. By default this option is enabled for Feature and Plug-in based products to behave the same like when the product is build with Eclipse Tycho.

Automatically include requirements in product

Products launched from IDE now better behave like products built with Maven/Tycho Launching a Product from within the IDE via the Product Editor has been improved in the following aspects to result in an application whose set of plug-ins/features is as close as possible to what is assembled when the product is build by Maven and Eclipse Tycho:
  • Launching a product based on features creates a feature-based Launch Configuration
  • Missing requirements are included by default (as described above)
  • When launching a plugin-based product optional requirements are ignored by default when computing missing requirements
  • When automatically including requirements, fragments are not added just because their host-plug-in is included
Together with the Improved launching of Eclipse/Equinox applications in the previous release Eclipse 2022-03 it is now much simpler to set up products. As an example, to create the Eclipse SDK as a Product you only have to create a Product with basic settings via the Wizard, configure it to use features and add the org.eclipse.sdk feature. The Product is ready to launch. If you want Git support, just add the org.eclipse.egit feature and in case you want to develop Maven projects in your Product, just add org.eclipse.m2e.feature.
