README:
This file should be located at the top of the OpenJDK Mercurial repository
forest. This top or enclosing repository will include a "make" directory,
and a Makefile at the very top of the repository.
It should also include the 6 repositories: "jdk", "hotspot", "langtools",
"corba", "jaxws" and "jaxp".
This file should be located at the top of the OpenJDK Mercurial root
repository. This root repository will include a "make" directory,
and a Makefile for building the entire OpenJDK.
A full OpenJDK repository set (forest) should also include the following
6 nested repositories:
"jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp".
There are also several source downloads for the jax* repositories that
will be needed.
This one root repository can be obtained with something like:
hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7
To make sure you have all the nested repositories, you can run:
cd openjdk7 && sh ./get_source.sh
(This is identical to using the Mercurial Forest Extension command
'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7').
People unfamiliar with Mercurial should read the first few chapters of
the Mercurial book: http://hgbook.red-bean.com/read/
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.
0. Get the necessary system software/packages installed on your system, see
http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html
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.
1. If you don't have a jdk6 installed, 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 JDK 6.
3. Check the sanity of doing a build with the current machine:
2. Check the sanity of doing a build with your current system:
gnumake sanity
See README-builds.html if you run into problems.
4. Do a complete build of the jdk:
3. Do a complete build of the OpenJDK:
gnumake all
The resulting JDK image should be found in build/*/j2sdk-image

<h2><a name="hg">Use of Mercurial</a></h2>
<blockquote>
The OpenJDK sources are maintained with the revision control system
<a href="http://mercurial.selenic.com/wiki/Mercurial">Mercurial</a>.
If you are new to Mercurial, please see the
<a href="http://mercurial.selenic.com/wiki/BeginnersGuides">Beginner Guides</a>
or refer to the <a href=""http://hgbook.red-bean.com/">Mercurial Book</a>.
The first few chapters of the book provide an excellent overview of
Mercurial, what it is and how it works.
<br>
For using Mercurial with the OpenJDK refer to the
<a href=""http://openjdk.java.net/guide/repositories.html#installConfig">
Developer Guide: Installing and Configuring Mercurial</a>
section for more information.
The Forest Extension is not part of the Mercurial install,
and is optional,
but can be obtained with the following commands:
<blockquote>
<tt>
hg clone https://bitbucket.org/pmezard/hgforest-crew/overview/ <i>YourHgForest</i>
</tt>
</blockquote>
Once you have the file <tt>forest.py</tt>, you need to add these
lines to your <tt>${HOME}/.hgrc</tt> file:
<blockquote>
<tt>
[extensions]
<br>forest = <i>YourHgForest</i>/forest.py
</tt>
</blockquote>
<!-- ------------------------------------------------------ -->
<h3><a name="get_source">Getting the Source</a></h3>
<blockquote>
To get the entire set of OpenJDK Mercurial repositories
using the Forest Extension:
<blockquote>
<tt>
hg fclone http://openjdk.java.net/jdk7/jdk7 <i>YourOpenJDK</i>
</tt>
</blockquote>
To get the entire set of OpenJDK Mercurial repositories
without using the Forest Extension:
<blockquote>
<tt>
hg clone http://openjdk.java.net/jdk7/jdk7 <i>YourOpenJDK</i>
<br>cd <i>YourOpenJDK</i>
<br>sh ./get_source.sh
</tt>
</blockquote>
Once you have all the repositories, the
script <tt>make/scripts/hgforest.sh</tt>
can be used to repeat the same <tt>hg</tt>
command on every repository in the forest, e.g.
<blockquote>
<tt>
cd <i>YourOpenJDK</i>
<br>sh ./make/scripts/hgforest.sh pull -u
</tt>
</blockquote>
You may find this script <tt>make/scripts/hgforest.sh</tt> faster
than the <tt>hg</tt> forest commands provided by the
Forest Extension.

<blockquote>
Not all of the source code that makes up the JDK is available
under an open-source license.
This is a temporary situation and these binary plugs will be
replaced with fully open source replacements as soon as possible.
So currently, in order to build a complete OpenJDK image,
you must first download and install the appropriate
binary plug bundles for the OpenJDK, go to the
<a href="http://openjdk.java.net" target="_blank">OpenJDK</a> site and select
the
"<b>Bundles(7)</b>"
link and download the binaryplugs for
your particular platform.
The file downloaded is a jar file that must be extracted by running
the jar file with:
<blockquote>
<pre>
<tt><b>java -jar jdk-7-ea-plug-b<i>nn</i>-<i>os</i>-<i>arch</i>-<i>dd</i>_<i>month</i>_<i>year</i>.jar</b></tt>
</pre>
</blockquote>
A prompt will be issued for acceptance of these binary plug files.
During the OpenJDK build process these "binary plugs"
for the encumbered components will be copied into your
resulting OpenJDK binary build image.
These binary plug files are only for the purpose of
building an OpenJDK binary.
Make sure you set
<tt><a href="#ALT_BINARY_PLUGS_PATH">ALT_BINARY_PLUGS_PATH</a></tt>
to the root of this installation.
