  == Overview of what's going on ==
--We're going to check out the latest source for WOLips, build it and arrange for Eclipse to launch is a debug mode to test it out.  It's very handy that Eclipse has a built in ability to launch itself in debug mode and load the local versions of the plugins.  If you read the old and out dated instructions floating about that talk about building an entire release and installing them into a new copy of Eclipse then you're going to like this method a whole lot better ;-)

  === Check out the source code into a local folder ===
  You're checking out a local copy of the code from the source repository.  Next, we're going to selectively import (but **not** copy) parts of that code into Eclipse.   I'm using command line subversion to check out the lastest version however feel free to use a different tool or different version, as you like.
--git clone [[git://github.com/wolips/wolips.git]] /woproject
++svn co https:~/~/svn.objectstyle.org/repos/woproject/trunk/woproject ,,/woproject,,
  Note that I've checked out the source code into my home folder.  It doesn't matter where you put the source code as long as you can find it in the steps below.

  Launch a clean copy of Eclipse with no plugings installed.  Strictly speaking, probably not necessary however these are the steps which I took.
  Create a new Workspace
--I chose /WOLipsDebugging
--[[image:Workspace.png]]
++I chose ,,/WOLipsDebugging
++[[image:Workspace.png]],,
--=== Import woenvironment ===
++=== Import woenvironment  ===
--Start off by importing the woenvironment project.  From the File menu, select Import
--[[image:ImportMenu.png]]
--Click the disclosure triangle for General and select Existing Projects into Workspace
--[[image:ExistingProject.png]]
--Click Next button.
--Ensure that "Select root directory" is selected and click Browse
--Browse to the folder where you checked out the woproject source code above and select woenvironment.
--[[image:woenvironmentCheckout.png]]
--Eclipse should scan the folder and notice one project in the folder called woenvironment.
--**It's important that you don't have 'Copy the project into your workspace' selected.**
--[[image:woenvironmentProject.png]]
--Click Finish.
--
--Once Eclipse has finished building the project, there should be no errors  If that's not the case, then you need to back up and make sure that you've followed all the steps above.
--
  === Import wolips projects into your workspace ===
--Repeat the steps above and import all the wolips projects except for 3
--EntityModler, eomodeldoc and org.objectstyle.wolips.eomodeler.factories
--are special projects which require special setup and caffination before touching.
--
--The import of wolips should look like this:
--[[image:wolipsImport.png]]
--
--And Eclipse should identify a whole bunch of projects.
--**Make sure that you deselect the 3 special cases noted above**
--The list of projects should look something like this:
--[[image:wolipsProjects.png]]
--
--Click Finish and the projects should all be imported.
--
--{{note}}
--
--When I did this I got the following error message.
--I have no idea what this means...
--!ResourceErrorMessage.png!
--
--{{/note}}
--
--Once Eclipse finishes building the projects there are going to be a whole bunch of build errors.  Don't Panic.  Most of them will resolve themselves after the next steps.
--
  === Import wolips plugins ===
--In the same way as above, import the core plugins from wolips/core/plugins.  Something like this:
--[[image:corePluginImport.png]]
--[[image:corePluginProjects.png]]
--
  === Import 3rd party plugins ===
--Finally, import the third party plugins from wolips/3rdparty/plugin.  Something like this:
--[[image:thridPartyImport.png]]
--[[image:thirdPartyProjects.png]]
--
  === Close special projects ===
--In case you missed the notices above, close these projects.
--
  * EntityModeler
  * eomodeldoc
  * org.objectstyle.wolips.eomodeler.factories
--(Note: Working on these projects is beyond the scope of what I needed to do. Sorry.)
  === Close projects which require additional resources to compile ===
--These projects require additional resources to compile.  As I didn't need them, I just closed them.
--
--* org.objectstyle.wolips.apple.mavenintegration
  * org.objectstyle.wolips.groovy.ui
  * org.objectstyle.wolips.jprofiler.launching
--=== Error message: Libraries not found for JavaEOAccess and other WebObjects libraries ===
--
--A couple projects have been committed to the repository with references to WebObjects libraries in /Library/WebObjects/lib.  You'll need to update these to the correct location on your machine.  If you've done nothing special to your WebObjects environment then this should be something like: /System/Library/Frameworks
--If you've done something else then you'll need to change the library locations (or perhaps update your WOLips properties file.)
--
--=== Error message: Cannot find artifact for parent POM... ===
--
--When building woenvironment, you might hit this error:
--Cannot find artifact for parent POM: org.objectstyle.woproject:woproject-all-parent::2.1 for project org.objectstyle.woproject.ant:woenvironment:jar:2.1-SNAPSHOT at /Users/...
--
--The simple solution is delete the pom.xml file.  Full details are here: [[http://wiki.objectstyle.org/confluence/display/WOL/mail/6259075]]
--
--== The configuration setup ==
--
--At this point, you should have a long list of packages which should all be compiling.
--If that's not the case, please document additional steps here, making special note of your setup.
--
--Getting on with the configuration to be able to test the software which is now compiling.
--From the Run menu, select "Debug Configurations ..."
--[[image:debugConfiguration.png]]
--
--Select "Eclipse Application" from the list on the left
--and then click the "New" button at the top.
--[[image:newLaunchConfiguration.png]]
--This creates a new launch configuration which you can customize as you like.
--By default it's called 'New//configuration'.  For this session, I named it DebugEclipse//
--
--My preference is to explicitly set the workspace for testing however I'm sure the default will be fine if you like it.
--I chose: $workspace//loc}/../WOLipsDebuggingWorkspace
--My setup looked something like below however there are lots of configuration options which I didn't need to explore:
--[[image:debugConfigured.png]]//
--
--== Launch the debug version ==
--
--Click the Debug button in the debug configuration window to launch the test version.
--This will be a clean version of Eclipse with the workspace which you set and any other settings.
--By default, all of the plugins are loaded and ready for testing
--And now, you should be running inside the debug version of Eclipse with all the wolips bits to play with
--
--== Snow Leopard Update ==
--
--I was running the carbon version of Eclipse 3.4.2 Build id: M20090211-1700 on Snow Leopard 10.6.2
--Up to this point, I was following the instructions above however when I tried to launch Eclipse, I got this error:
--
--{{code value="java"}}
--
--java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM
--	at org.eclipse.swt.internal.Library.loadLibrary(Library.java:177)
--	at org.eclipse.swt.internal.Library.loadLibrary(Library.java:151)
--        ...
--
--{{/code}}
--
--This is a known problem and is documented here: [[http://www.eclipse.org/swt/faq.php#cocoa32launch]]
--The fix is to add the d32 parameter to the launch arguments.
--
--Original:  os $target.os} ws $target.ws} arch $target.arch} nl $target.nl}
--Updated:   os $target.os} ws $target.ws} arch $target.arch} nl $target.nl} d32
--
--A second problem which I encountered was running out of memory while running test version of Eclipse
--I had to add the VM argument "-Xmx2G" and then 'Run' as opposed to 'Debug' the app.  For the most part, that worked.
--
--My final setup looked like this:
--[[image:32Bit_jvm_2GB_mem.png]]
--
--== There was more than one SQL reverse engineer factory defined. ==
--
--[[image:MoreThenOneReverseEngineeringFactory.png]]
--This exception occurs when you've forgotten to close the org.objectstyle.wolips.eomodeler.factories project.
--The fix is to close the project.  Thanks to Mike Schrag for putting me on the right path when I was at my wits end with this damn problem.
