I've been fighting with a problem where I could not package one of my tools as a geoprocessing package. After lots of trial and error I found that it was connected to a totally innocuous try/except in my code. When the try/except is in the code (see below - for illustration purposes only), the publishing fails with an error message that provides no clue. I noticed at some point that if I highlight the problem tool in the Catalog then click Properties -> Parameters I get this message
When I remove the try/except, I can view the properties OK, and more importantly the publish works. I'm not a python expert so maybe there is a good explanation about how a try statement like that could have such a side effect - I'd love to hear it.
For my tool I was able to do some recoding and get around the problem. But if you are having trouble with publishing, perhaps a good test is to make sure the tools parameters are viewable via the tool properties.
