This file should be located at the top of the jdk Mercurial repository.
See http://openjdk.java.net/ for more information about the OpenJDK.
Simple Build Instructions:
1. Download and install a JDK 6 from
http://java.sun.com/javase/downloads/index.jsp
Set the environment variable ALT_BOOTDIR to the location of this JDK 6.
2. Download and install the Binary Plugs for the most recent JDK7 from
http://download.java.net/openjdk/jdk7/
Set the environment variable ALT_BINARY_PLUGS_PATH to the location of
these binary plugs.
3. Either download and install the latest JDK7 from
http://download.java.net/openjdk/jdk7/, or build your own complete
OpenJDK7 by using the top level Makefile in the OpenJDK Mercurial forest.
Set the environment variable ALT_JDK_IMPORT_PATH to the location of
this latest JDK7 or OpenJDK7 build.
4. Check the sanity of doing a build with the current machine:
cd make && gnumake sanity
See README-builds.html if you run into problems.
5. Do a partial build of the jdk:
cd make && gnumake all
6. Construct the images:
cd make && gnumake images
The resulting JDK image should be found in build/*/j2sdk-image
