Every wanted to make this unsigned prompt dialog go away when you’re installing things into Eclipse?
Well, the best way to get rid of this dialog is to actually sign your JARs like most mature Eclipse.org projects do. At first I didn’t think it was possible to remove this dialog without signing your JARs, however, after working with a colleague I discovered the eclipse.p2.unsignedPolicy system property (you learn something new everyday, right?). For example, if you didn’t want this dialog to appear, you can set -Declipse.p2.unsignedPolicy=allow when your Eclipse-based application starts up. The valid values for eclipse.p2.unsignedPolicy are:
- prompt – user is prompted for confirmation when installing unsigned content (default value)
- fail – installing unsigned software is never allowed and the install will fail
- allow – installing unsigned software is always allowed and the user is never prompted (3.4 – 3.5 behavior)
