Description

I have been trying to use latest Grails on Windows 7 SP1, Core i5, Cygwin - but the grails scripts are not accepting user input... it just hangs there waiting, even though I type 'y' to the question. When you CTRL-C, bash thinks the 'y' has been typed as the next command. (Everything was OK on 1.3.7 and 1.4.0.M1)

[03/11/2011 @ 21:58 - just tried 2.0.0.RC1 in Command Window and all OK, so this is an issue interacting in Cygwin/Bash. I also just dropped grails back to 1.4.0.M1 and Cygwin/Bash works OK. This issue is important to me as I am in a locked down environment and am blocked from using Command Window]

 You currently already have a version of the plugin installed

Any pointers / suggestions cos I am pulling my hair out...

I am also seeing this problem on Cygwin on Win7. Specifically, using the "Cygwin Terminal" provided by a brand new install of Cygwin (rather than older Cygwin terminal emulator approaches - though I haven't tried them), I can type grails to go into interactive mode, but then anything I type is ignored and when I give up and ctrl-C to escape grails, it then runs the text I typed as the command prompt. So something's not hooked up right. This is indeed a bit of a problem for Windows developers, though I can workaround it by using a normal Windows cmd prompt.

Does this problem occur with the 2.0 release? (the original issue was filed against 2.0-RC1)

Yes, this is still a problem as of release 2.0.0

In fact it's a show stopper for me in a locked down, corporate environment, within a major UK retailer.
Cmd Window is disabled, so I need to use cygwin to drive the command line.
The MSDOS prompt is available and allows me to run the scripts and enter input, but it's unusably clunky for day to day use.

I have dropped back to 1.3.7 for moment.

Does anyone know if STS uses Cmd Window as a background process to the IDE when running commnad lines, or is there something more sophisticated going on under the hood... was wondering if that might be another workaround for me?

Could be related to http://softwaremavens.blogspot.com/2009/10/cgwin-interpretersjline-carriage-return.html

Could someone try run the grails command inside cygwin with:

grails -Djline.terminal=jline.UnixTerminal

Below is output on WinXP SP3.

Interestingly, I have managed to install STS 2.9.0.M2 here, download grails support and grails 2.0.0 inside STS and I can create a simple domain and run it - however, I get the same RegCreateKeyEx error on stderr.

bash-3.2$ which grails

I installed Cygwin myself and if I use the jline.UnixTerminal parameter then user input works fine:

I've just had an AHA! moment regarding Grails on Cygwin on Windows - which I will share and hope it helps others...

I've been typing [b]grails[/b] because I thought that Cygwin would do the right thing and run the *nix commands on top of windows. I tried the command line options suggested but they don't make things work.

I presume the intention is still to fix [b]grails[/b] and not force use of [b]grails.bat[/b] ?

In the meantime I have managed to get STS 2.9.0.M2 up and running on both my personal Win7 laptop and corporate WinXP PC... so think I will try that route for a while...
