2 This file should be located at the top of the OpenJDK Mercurial root |
3 forest. This top or enclosing repository will include a "make" directory, |
3 repository. This root repository will include a "make" directory, |
4 and a Makefile at the very top of the repository. |
4 and a Makefile for building the entire OpenJDK. |
5 It should also include the 6 repositories: "jdk", "hotspot", "langtools", |
5 A full OpenJDK repository set (forest) should also include the following |
6 "corba", "jaxws" and "jaxp". |
6 6 nested repositories: |
|
7 "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp". |
|
8 There are also several source downloads for the jax* repositories that |
|
9 will be needed. |
|
10 |
|
11 This one root repository can be obtained with something like: |
|
12 hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7 |
|
13 To make sure you have all the nested repositories, you can run: |
|
14 cd openjdk7 && sh ./get_source.sh |
|
15 (This is identical to using the Mercurial Forest Extension command |
|
16 'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7'). |
|
17 People unfamiliar with Mercurial should read the first few chapters of |
|
18 the Mercurial book: http://hgbook.red-bean.com/read/ |
