Remove the ${buildKey} from Clover plugin URLs

Problem:

The 'aggregate' view of the Clover plugin contains ${buildKey} in the URL. It is fine for the standalone Bamboo installation:

but fails on OnDemand (I guess there are some security restrictions applied):

Steps to reproduce:

Enable Clover in the project. Run build with Clover to generate HTML/XML reports. Open the Plan Summary page, click on the Clover tab.

Suggested fix:

Change the <web-item key="..."> so that it will not contain anything with ${...}

Workaround for OnDemand:

Replace the buildKey by the actual project-plan-job identifier, for instance:

https://your.bamboo.server/builds/build/viewCloverSummary.action?buildKey=PROJECT-PLAN-JOB1
