[kepler-dev] Kepler source + eclipse

[David Welker]

Hi Michal,

1.) First, I made sure I was starting fresh by deleting both my old 
kepler.modules folder and my workspace and running "ant clean-cache."

2.) First I entered the following commands at the command-line.

First, I navigated to my home directory.

mkdir kepler.modules
cd kepler.modules/
svn co https://code.kepler-project.org/code/kepler/trunk/modules/build-area
cd build-area
ant change-to -Dsuite=kepler-trunk
ant eclipse

3.) I then clicked on eclipse to open it and had it open up a fresh 
workspace.

4.) Then I selected File --> Import... and chose General --> Existing 
Projects Into Workspace and hit selected Next.

5.) I ensured the Select root directory radio button was selected and 
chose browse. I then selected the kepler.modules folder and waited for 
the projects I had generated using the ant eclipse command to come up. 
All of the modules associated with kepler-trunk were visible and 
available. I then clicked on Finish.

6.) From the Package Explorer pane, I right-clicked on the loader folder 
and selected Run As --> Run Configurations. I then made sure that the 
Java Application item was highlighted and hit the "New launch 
configuration" button. I specified kepler-trunk as the name of the 
configuration (you can name it anything you want) and made sure that the 
Project: was specified as "loader." I entered in 
org.kepler.core.loader.Loader as the main class and selected the 
"Include inherited mains when searching for a main class" check box 
(this shouldn't be necessary in this case since 
org.kepler.core.loader.Loader in fact exists in the loader project, but 
for the sake of consistency, I just do it every time.) I then selected 
Apply and then Run.

It worked just fine. I am not sure what is going on for you. I am using 
a Mac OS X 10.5 and running with Java 1.5 and Ant 1.7.1. I am using 
Eclipse 3.4.1 (Ganymede). I am going to upgrade to 3.4.2 to ensure that 
it still works there, but I am assuming it will.

Please let me know when you figure it out...

David
