Hi,

I tried running ProM 6.0 UITopia using Eclipse, and it gave me this error:

I would appreciate some help if anyone could explain to me what this error is about, and how do I solve it? Thank you for your help!

Hi,

I never encountered this error, but I would have tried the following:

1. Do a fresh checkout of the source.

2. Clear the plugin cache and retry running.

Have you already tried these?

Thanks,

PCoder

Hi PCoder,

Thanks for the suggestion. I did a fresh ckeckout of the source and deleted the .ProM and the UITopia folder before trying to run it again. It's working now, just that it got stuck every time it tries to download/update its packages (I just cancelled the update and proceed).

Thank a lot again.

Cheers,

Keith
