hi folks, i have:

IntelliJ IDEA 2016.3.2
Build #IU-163.10154.41, built on December 21, 2016

JRE: 1.8.0_66-b18 amd64
JVM: Java HotSpot(TM) 64-Bit Server VM by Oracle Corporation

on Windows 7 64 bit

i would like run cygwin bash as my terminal, but when in tools i set as a shell path: C:\cygwin\bin\bash.exe --login -i

i raise error "java.io.IOException: Couldn't create a PTY"

when i create a .bat file bash.bat and into i include 'C:\cygwin\bin\bash.exe --login -i' and run this .bat file, it works.

why?

I'm using Git Bash in my IntelliJ and for the path I had to put quotes around the path for it to work.

Try  "c:\cygwin64\bin\sh.exe" -c "/bin/xhere /bin/bash"

Try "c:\cygwin64\bin\sh" -lic "cd ${OLDPWD-.}; bash" @Glli80's Answer worked for me! Thanks! Choosing the path to Cygwin.bat in the root of Cygwin directory as the command worked for me. For me it was - c:\software\cygwin\Cygwin.bat I would like to improve the Glli80's answer (since by default my bash profile was not executed): "c:\cygwin64\bin\sh" -lic "source ~/.bash_profile; cd${OLDPWD-.}; bash"

Affkar's answer worked for me. I had to reread his comment to understand it's the root directory of the Cygwin folder (cygwin\Cygwin.bat) not the bin folder (cygwin\bin\Cygwin.bat). His answer also ran all of the profiles correctly.

thnak you for improving Esgorbachev

I believe the root problem is that the Cygwin shell is executed by Idea using the full source path rather than using the environment PATH variable.  And since Cygwin doesn't add the /bin path to the Systems Environment Path, a lot of basic commands (like ls) aren't available when sourcing your .bash_profile and .bashrc files.

The solution is trivial.
And take the -i and --ignore out of your shell path, like so:

Finally, clear any value you may have stored in the "Start directory" setting.  This will make your terminal open in the correct directory for each project.

You'll need to restart Idea so it sees the correct Path, but after that your Terminal Shell will work perfectly.

I was having nothing but problems getting IntelliJ to work with Cygwin + my bashrc + cd to project root.

Cygwin.bat calls bash --login -i from the bin directory; however, using "C:\path\to\cygwin\bin\bash" -li in IntelliJ would leave me at my home directory (the cd to project root wasn't working). Using the sh -lic "cd here; bash" trick to run a command and leave the terminal open was failing completely due to my cd function (pushd not available). Even tried sh -c "cd here; bash -li". Nothing worked. That is, until I tried Dave's answer. I figured it wouldn't work, since -li seems to be important. However, I was so wrong.

1. Ensure bin is in Path (you should have done this as part of your initial Cygwin installation). (Not 100% sure this is required, as I already had it set.)
2. Call bash with no arguments. Shell path C:\tools\cygwin\bin\bash

My bashrc was processed and the terminal opens to the project root. So simple! Too simple to think it works, but it does.

@Derek White

Thanks Derek, Glad to help out.  It seems that every accepted solution out there (including StackExchange) goes with the incorrect "-li" approach.  Very frustrating.  It was nice to see that IntelliJ code actually behaves correctly when the env (Path) was correctly defined.

@Gill80's answer works great except for paths with spaces. To fix this do:

"c:\cygwin64\bin\sh" -lic 'cd "\${OLDPWD-.}"; bash'`

The additional double quotes will force the environment variable into a single entity even if it has a space.

@Glli80's Answer worked for me! Thanks!
