With recent improvements to the GlassFish code base, developers are now able to build the entire GlassFish trunk in only a few minutes.
In addition to all the work that has consistently been done to have a fast and robust build, we're now putting both Maven 3.0.3 as well as JDK 7 to work. This is all fully documented in this GlassFish Full Build Instructions wiki page.
This can only help the entire team deliver promoted and milestone builds for the upcoming GlassFish releases. More on that in another post.
