[kepler-dev] Reg. problem running kepler

[Christopher Brooks]

Hi Sivagowri,

I updated the Kepler/Eclipse install instructions, see
http://www.kepler-project.org/Wiki.jsp?page=UsingEclipseForKeplerDevelopment

You should use org.kepler.gui.KeplerApplication instead of
VergilApplication.

I apologize for any confusion here.

Also, I selected ptII as a subproject instead of using ptolemy.jar 
and ptolemy-doc.jar. 

I can reproduce the ClustalW error in a tree when working from
within the Cygwin bash shell

I checked out a clean ptII and kepler tree and did
  ant ptolemy buildkarlib run-dev
and got

>kar:
>     [echo] Generating kar file: ClustalW

>C:\tmp\cxh\kepler\build.xml:806: The following error occurred while executing th

Dan's excellent suggestion of running cvs update -P -d fixes this for
me.  I did not see this error in when running from Eclipse though,
I only saw it when building from the shell.

    Hi Siva -
    
    Don't want to step on Christopher's toes, but I know he's busy, and I 
    don't think this is a Ptolemy problem, so here goes...
    
    I don't use Eclipse, but have seen similar problems with JBuilder. The 
    error message about "could not parse the argument '-kepler'" is 
    typically misleading, since the real cause is often something entirely 
    different, and you have to look further down the stacktrace for the real 
    problem. In your case, I see this:
    
      "...Caused by:
      java.lang.ClassNotFoundException: org.kepler.gui.LibraryPaneFactory..."
    
    - so I'd check that org.kepler.gui.LibraryPaneFactory is indeed present 
    in your source directory, and has been compiled successfully to your 
    build directory, and that the build destination is on Eclipse's classpath.
    
    (Since you had some manifest files missing, it sounds like you may have 
    an incomplete checkout of the kepler tree, so it would be worth 
    checking, if you didn't already)
    
    
    Other problems like this have been caused for me by:
    
    1)  not having the configuration files in the IDE classpath, too. My 
    current classpath additions for config files and other resources are as 
    follows:
    
    /Users/brooke/dev/KEPLER/kepler
    /Users/brooke/dev/KEPLER/kepler/lib
    /Users/brooke/dev/KEPLER/kepler/lib/images
    /Users/brooke/dev/KEPLER/kepler/configs
    
    Try adding those in Eclipse if you didn't already
    
    2) by the (yourHomeDirectory)/.kepler directory being corrupt/out of 
    date/otherwise wrong. To fix this, you can delete the 
    (yourHomeDirectory)/.kepler directory, the kepler/build directory, and 
    also the kepler/kar directory, and then do an "ant buildkarlib run-dev"
    
    Good luck!

   ain class. But when I run, it produced some errors saying , it could not par
   se the argument '-kepler'. In fact, the error happens for any argument and n
   o argument cases.
