Version History

No longer documented here. Go to the releases tab

Version 1.7.7

  • Bug fix whereby sometimes the Waiting page would sit there for ever. Due to content script not being injected. Seems the content script is always injected now as I inject it with code rather than in the manifest.json declaration

Version 1.7.6

  • Release fixes

Version 1.7.5

  • Added

Version 1.7.4-Styling

  • Styling of User interface

Version 1.7.3-All URLS

  • Supports running IQ Server on any URL
  • Fixed various bugs

Version 1.7.2-added new formats

  • added new formats
  • Fixed various bugs
  • Added unit tests
Formats/package manager pages supported as of 1.7.2

Version 1.7.1 - Fixed popup

  • Fixed popup logic bug.
  • Began adding testing

Version 1.7 - initial release

Complete rewrite to fix cookie problem with calling Nexus IQ Server. I have decided the best way to fix the security issues for now is to limit access to http://iq-server:8070. So you will have to alias your localhost as iq-server in your /etc/hosts/ file to use this plugin for now. I will think about a change which gives access to all URLS like so below

Add *://*/* to permissions section like so

"permissions": [ "*://*/*",

This would then mean you would not need to alias Nexus IQ.

Supports scanning components in the following repos

The Fine Print

It is worth noting that this is NOT SUPPORTED by Sonatype, and is a contribution of ours to the open source community (read: you!)


  • Use this contribution at the risk tolerance that you have
  • Do NOT file Sonatype support tickets related to chrome-extension support in regard to this project
  • DO file issues here on GitHub, so that the community can pitch in

Phew, that was easier than I thought. Last but not least of all:

Have fun creating and using chrome-extension, we are glad to have you here!

You can’t perform that action at this time.
