This page describes problems related with generation of Clover's HTML, XML, PDF or JSON reports, including but not limited to: lack of coverage data, lack of per-test coverage, wrong classification of application vs test classes, rendering source code view. 

• Can't connect to window server - not enough permissions thrown when building clover report.
• Clover registry file <path/to/clover.db> does not exist
• Coverage appears incorrect and code is not being matched to tests, per-test coverage
• Ignoring coverage recording files
• Inner classes of test classes shown as source code
• IOException during generation of HTML report
• No coverage recordings found. No report will be generated.
