Eclipse plugins not loading automatically

I have done a few Eclipse plugins, and when developing, I always place the new versions of the plugin into the eclipse\plugins folder on the installed Eclipse target, and when I launch Eclipse, they are loaded.

I'm now updating a plugin that was targeting Luna, now to work in Oxygen.3. I've rebuilt the plugin using Oxygen.3 Eclipse for Eclipse Committers, and then place the resultant output .jar file into the target Eclipse plugins folder, along with the new dependencies my plugin needs (namely several WST modules). But when I launch Eclipse, the plugin won't load automatically.

If I launch Eclipse with -console option, I can then try to manually load the plugin from the console:

osgi> install reference:file:plugins/com.mystuff_1.0.0.201805181701.jar

Then using the console diag command to check if the dependencies were satisfied, it gives:

  Unresolved requirement: Require-Bundle: org.eclipse.wst.sse.ui; bundle-version="1.3.600"

I can then load that via console via install command:

install reference:file:plugins/org.eclipse.wst.sse.ui_1.3.600.v201707042340.jar

diag again shows that the wst.sse.ui plugin has unresolved requirements - basically, repeat the cycle for each of the 8 WST related plugins that are in the dependency tree. Finally, all dependencies are satisfied, the diag command gives:

osgi> diag 355
com.mystuff [355]
  No resolution report for the bundle.

At this point, my plugin is active and can be debugged.

What am I missing? Why won't the plugins load automatically?

Since the introduction of the Provisioning platform (p2) in Eclipse Ganymede (3.4) the plugins folder is no longer scanned for changes. Instead, the dropins folder is scanned (see also Eclipse 3.4 - New and Noteworthy - New dropins folder):

  • Place the new versions of your plug-ins into the dropins folder instead of into the plugins folder.
  • Alternatively, you can install the plug-ins directly into your running Eclipse IDE when exporting the plug-ins (see Eclipse Help: Export and Install into the Running Host).
