Description Alexander Pepin 2011-03-09 14:52:18 UTC

While working with full remote project on windows exclamation window with the message "Error syncronazing project to <login>@<host> null" appears quite often.

IDE log contains:
INFO [cnd.remote.logger]: Error synchronizing project to tester@amkar: null

Comment 1 Vladimir Kvashin 2011-03-10 05:57:12 UTC

I made a better diagnostics for this (just pushed: http://hg.netbeans.org/cnd-main/rev/8eb9ca043685) - a stack is printed in log in addition.
Should this happen again, please attach the stack.

Comment 2 Quality Engineering 2011-03-11 09:40:16 UTC

Integrated into 'main-golden', will be available in build *201103110400* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: better diagnostics for #196501 Error synchronizing project

Comment 3 Leonid Lenyashin 2011-03-12 12:52:34 UTC

Is it "incomplete"?

Comment 4 Vladimir Kvashin 2011-03-14 06:46:02 UTC

I'm not able to reproduce this.
Should it repeat, please reopen and attach stack trace from IDE log.

Comment 5 Alexander Pepin 2011-03-14 14:55:37 UTC

Now "Error synchronizing..." appears on deleting imported full remote project:

Comment 18 AlyonaStashkova 2011-04-05 11:51:45 UTC

Added to NB 7.0 Release Notes

Comment 19 Vladimir Kvashin 2011-04-05 12:25:20 UTC

Workaround: just ignore this message. 
Your project will be synchronized to remote host next time (when you change project or item properties or just build the project).

Comment 20 Vladimir Kvashin 2011-05-04 11:38:32 UTC

No shadow projects - no issue :)
