I would even recommend having project specific preferences enabled whenever possible. This will ensure all developers are reported for problems and their workspace settings doesn't have them ignored.

PDE Good Practices: #7 Keep build.properties synced
We often land up in situations like "it was working in my workspace but exported plugins are behaving differently". An important thing to notice is that workspace is build considering the project classpath settings. However, the Export wizard or headless build does not have access to it. They reply on build.properties file. Thus it is very important to keep it in sync with the project settings. Eclipse Helios (3.6) added a bunch of preferences to help you do just that.
