Building Apache OpenJPA
Licensed under Apache License 2.0 - http://www.apache.org/licenses/LICENSE-2.0
--------------------------------------------------------------------------------

These instructions describe how to build OpenJPA 2.2 from source code using the
Apache Maven 2 build tool. They are written for use from the console, and are 
known to work on Windows, Linux and Mac OSX.

The most up to date version of these instructions may be found on the OpenJPA 
website at http://openjpa.apache.org/building.html

   1. Ensure that Java SE 6 is installed and on your path by running:
          java -version
      OpenJPA requires Java 1.6 or later to build and for runtime.
   2. Install the build tool Apache Maven 2.2.1 or later, from:
          http://maven.apache.org/
      If it is installed correctly, typing mvn -v from the console will result
      in the text like "Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)"
   3. Extract the source archive if you have not already done so. 
      The source will create a new directory named:
      openjpa-<version>-source. Where <version> is the OpenJPA 
      version, for example apache-openjpa-2.2.0-source.
   4. Change to the OpenJPA source directory, which has already been created in
      the previous step.
   5. Build OpenJPA by running: mvn package or better mvn install. 
      The first time you run the build, many dependencies are automatically 
      resolved and downloaded. It is common for dependency downloading to fail
      the first time, which will fail the build. If any of these dependency 
      downloads fail, just re-run the command. You may also add the following 
      to your ~/.m2/setting.xml file
      (see http://maven.apache.org/guides/mini/guide-mirror-settings.html)

       <settings>
           <mirrors>
               <mirror>
                   <id>repo.mergere.com</id>
                   <url>http://repo.mergere.com/maven2</url>
                   <mirrorOf>central</mirrorOf>
                   </mirror>
           </mirrors>
        </settings>

        If any tests fail, and you want to ignore the failures, instead run:
        mvn package -DskipTests

An example session is as follows:

$ cd /tmp/

$ java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode)

$ mvn -v
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
