With the transition of the
java.net site to a new infrastructure, the time has come to retire the long-hosted but dormant
apt mirror API project,
The old source bundles in the project are just the JDK 5
apt API; the implementation was not included. This
apt project predated OpenJDK; with OpenJDK, the
apt API and implementation (and much, much more!) has been available under an open source license for several years.
Additionally, annotation processing should transition away from the first-generation
apt to the much-improved and standardized JSR 269 annotation processing available since JDK 6 and supported directly in
javac. Moreover, the
apt tool and API have been deprecated as of JDK 7.
Purely for historical interest, I'm placing an archive of the
apt source bundles on this blog:
