Re: [ptp-user] building ptp perspective issues

[Jonathan Chu <jrchu@xxxxxxx>]

I can't load any of the preference pages for PTP. I did not get any

The errors are like:
plug-in org.eclipse.ptp.simulation.ui was unable to load class
org.eclipse.ptp.simulation.ui.preferences.SimulationPreferencePage
