ViewTracker Plugin failed to install
Asked by Erleene Lyder:

Hello,

I'd like to install the ViewTracker Plugin onto Confluence, however, after attempting to install it, I have the following error message:

body: Hi,

cannot help you in detail but maybe explain the stacktrace. The viewtracker 3.0.5 plugin requires additional libraries and has to make them available with OSGi dependencies. The three errors occur because the following packages (required) cannot be found by the UPM installer:

* org.randombits.supplier.core
* org.randombits.supplier.core.annotate
* javax.mail.internet

I made the experience that sometimes this is not because of the missing libraries - you can check this opening the obr file - the UPM itself seems to have a problem while trying to resolve the dependencies. Re-install the plugin or restart confluence might help.

BTW I tested to install the viewtracker 3.0.6 with the confluence 5.4.2 - it just worked.

HTH
