We've just moved the HK2 repositories to the new JavaEE organization on Github.
The repositories can now be found at :
The previous organization is now a placeholder with a link to https://github.com/javaee/hk2
Note that this move will impact you only if you had direct clones of the HK2 repository.
Existing forks should not be impacted.
A new website is also available at https://javaee.github.io/hk2
The java.net redirect should come soon.
