Hello:

Nice technology!

I have downloaded and installed the ingeneration build
(I200708031400-200708031400) and configured the
Window->Preferences->Ruby->Interpreters manager as described in an earlier
note.

When I attempt to run a simple script I get the error message on the
console: "The system cannot find the path specified."

Any suggestion on how to proceed and troubleshoot?

I am operating on windows XP, eclipse 3.3, and europa. I've also provided
about a half dozed directories to the jruby system libraries.

Thanks in advance.

Steve

Upon further investigation I am seeing a java.io.FileNotFound exception
being throw because the file:
~/.metadata/.plugins/org.eclipse.core.runtime/.settings/ecli pse.dltk.debug.prefs
is expected but not found.

Can one of the dltk/ruby developers try creating a clean new run environment
and see if this problem is true?

I've also tried putting an empty file in this location, but there are
additional start-up problem. I believe I'm also seeing an IOException on
file metadata\.plugins\org.eclipse.dltk.core\path.rb (which is present), but
I'm not totally sure about this.

Thanks for any help.

Steve

Hello Steven,

The problem you described is very strange. I've created clean new
workspace and jruby works correctly there, at least the simple "puts
'Hello, World'". Interpreter search also works.

Please, if it possible, provide the stack trace of
FileNotFoundException, this should greatly help us to fix the problem.

By the way, I've also checked the ".settings" directory on my machine
and it doesn't contain "eclipse.dltk.debug.prefs". All files in this
folder has names begins with "org.eclipse", e.g.
"org.eclipse.debug.ui.prefs".

Hello Dmitriy,



Thanks for the assistance. The stack trace you requested is below.
Yes, something seems very strange, most likely some type of installation
problem, but I can't determine what.







Installation:

Windows NT

JDK 1.5.0

Eclipse 3.3

Europa

DLTK Integration Build I200708031400-200708031400





Configure:

Interpreter selected for both classical Ruby (1.8.6) and JRuby (1.0)

Note: I do not see external libraries automatically added when setting up
JRuby like is does for Ruby, but I manually add them anyway.



Run-time (.metadata/*) cleared out.



Project:

Create simple ruby project.

Create one line ruby script (i.e. puts "Hello World").



Works properly when script run with classical Ruby.



When run with JRuby, console gives error message: "The system cannot find
the path specified."



When run in debug mode with JRuby and exception break point set on
java.lang.FileNoFoundException, the back trace appended below is observed.
At one frame up from where exception is thrown in constructor
FileInputStream() I observer variable arg0->path =
" C:\\testlens\\proto7x\\dltkjruby\\.metadata\\.plugins\\org.e clipse.core.runtime\\.settings\\org.eclipse.dltk.debug.prefs "





Note: It seems odd to see observe error. It seems like running with
classical Ruby should have produced this error too. And furthermore, I'm
NOT even attempting to run the DLTK debugger. Something is strange.
However, I did install plugin org.eclipse.dltk.ruby.debug and debug.ui.



Steve
