If you encounter a problem with Nexus, you can use the Nexus UI to report a bug or file an issue against the Nexus project in Sonatype's JIRA instance. To file a problem report, you will first need to sign up for an account on http://issues.sonatype.org. In Nexus 1.6, you can click on "File Issue" in the Nexus menu, supply your Sonatype JIRA credentials, and file a problem report. Supply your JIRA username and password along with a short title and a description as shown in the following figure. When you file a Nexus problem report, Nexus will create a new issue in JIRA and attach your configuration and logs to the newly filed issue.
