Upgrading to Eclipse plug-in 1.0.19
If you have an earlier version of the plugin and try to update 10 1.0.19 you will probably get an error saying there is a conflict with the earlier version. In this case you will need to uninstall the earlier version, but BEFORE you do this make sure you save the KF plugin settings. The KF plugin stores data in two places, as preferences and as launch configurations. Preferences holds information about which frameworks, environments and repositories that have been configured. Launch configurations is all your debug/run configurations.
To save the preferences select File/Export..., in the dialog shown select General-Preferences and select next. Check the knopflerfish preferences, specify where to save it and finish. This file can later be imported to restore these preferences. This is also described here http://www.knopflerfish.org/eclipse_preferences.html
To save launch configurations select File/Export..., in the dialog shown select Run/Debug-Launch Configurations and select next. Check the knopflerfish launch configurations, specify directory to save to and finish. These launch configurations can later be imported.
