Older bundle version remain in plugin folder after update [message #1776881]

Hi,

i have migrated my application from rcp 3x to e4.

Before the migration the p2 update mechanism removed automatically older versions of updated bundles (at the same time two versions of a bundle exists in the build product). The plugin folder looks after an update from product version 3.0 to 3.1 like

bundle_x_3.0
bundle_x_3.1
bundle_y_3.0
bundle_y_3.1

and after an update from product version 3.1 to 3.2

bundle_x_3.1
bundle_x_3.2
bundle_y_3.1
bundle_y_3.2

After migration older bundles remain. After several updates the plugin folder looks like

bundle_x_3.1
bundle_x_3.2
bundle_x_3.3
bundle_x_3.4
bundle_y_3.1
bundle_y_3.2
bundle_y_3.3
bundle_y_3.4

Need help please.

Best regards

Stef

p2 doesn't clean up bundles immediately. Check your <<installDir>>/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info file and I suspect you'll only see your 3.4 versions referenced. Your bundles shouldn't be installed in your OSGi runtime, and p2 will garbage collect them eventually. The p2 FAQ has some details.

You can force a GC, which is covered in the p2 FAQ.

thank you very much for your response.

your are right, the bundles.info only contains the newest bundle version :)

i have tried to trigger the gc manually but nothing happens.
