Add support for @component injection

[hugoduncan]

Support injection of component fields.

The code for this is in place, but requires the fix for two sisu bugs to function.

• https://issues.sonatype.org/browse/SISU-110
• https://issues.sonatype.org/browse/SISU-111

These bugs are fixed and are waiting on the next maven release.

So should this now be working with Maven 3.0.4?

[hugoduncan]

Sould be. Maven 3.0.4 depends on sisu 2.3.0 which seems to include the relavant fixes.

I confirm this works.
