Where are the Luna Eclipse log filess [message #1575189]

Hi,

I've installed Luna and did some web development and that was okay. I just now wrote a short stand-alone java program executable from the command line. And when I tried to run it from within eclipse, I get the following message in the console window: Error: Could not find or load main class MergeSort. But when I tried to execute it from the command line, there was no issue with finding and it ran just fine. Since in the console window, Eclipse isn't providing any useful I want to look at the log files Eclipse generated. Back when, they were in a dot directory (hidden directory) at the top of the workspace, but I can't find them anywhere.

Where does Eclipse write it's internal logs?

Thanks,
Rob

Hi,

It seems that I found them. They are at the top of the workspace in .metadata/.log. But, there are no log entries that correspond to the time I try to run the program. So a new question: Any ideas about why executing the program within Eclipse returns a can't find main error, or at least some ideas about where I might look?

Thanks,
Rob

Often, then "things don't run at all", there is a configuration.log
file, in the configuration directory.
And, if running "from within Eclipse" you have to find the "runtime"
directory specified in that launcher.
By default, it's buried, deep under .metadata/plugins/<something>
<something>,
but you can specify it to some other location that's easier to find.
(Similar for the "runtime workspace" ... it's different than the
"workspace" associated with
the "outer" Eclipse instance you are running from.
Good luck!
