Description Jesse Glick 2008-09-03 19:49:19 UTC 
I have an XP installation in which I have added hg.cmd to my %Path%, so that running 'hg version' etc. from command.exe
works fine. (I use hg.cmd so I can build Hg from sources under Cygwin: './setup.py build -c mingw32' where hg.cmd runs
'python ....\scripts-2.5\hg') But NetBeans is not able to find the Mercurial command, even if I specify the containing
directory in the Options dialog. I should be able to have hg.cmd somewhere, and NB should use 'cmd /c hg.cmd ...' to run
it. (See org.netbeans.nbbuild.HgExec for ideas.)
Comment 1 Jesse Glick 2008-09-06 16:02:56 UTC 
I consider it a DEFECT (perhaps not P3) that running "hg" from a command shell works fine, yet NetBeans fails to do the
same, and does not even offer any kind of explanation. I only knew that the issue is *.cmd vs. *.exe because I happened
to be fixing a similar bug in nbbuild recently.
Comment 2 Jesse Glick 2008-09-06 16:04:41 UTC 
Note that there is also no good workaround: you can install a prebuilt public release of Hg, or go through the very
complex set of steps required to build hg.exe from sources.

> ...you can install a prebuilt public release of Hg
well, this is, i guess, how it was supposed to work and usually also works. Otherwise i would consider it a defect either.

anyway, nb explicitly checks for hg.exe. Even, if i'm not quite sure why, it looks like the fix shouldn't be a big deal.
Will fix asap.
Comment 4 Jesse Glick 2008-09-10 03:57:57 UTC 
You cannot Runtime.exec a *.bat or *.cmd directly; you have to 'cmd /c' it. (Similar to a Unix shell script with the
execute bit off.)
Comment 5 Tomas Stupka 2008-09-10 11:12:55 UTC 
nb already runs hgk.cmd, so this shouldn't be an issue here
Comment 6 Marian Petras 2009-04-29 14:38:21 UTC 
Done.
