Configuring IntelliJ's terminal to run Cygwin

.bashrc

# Add to your .bashrc so the terminal starts in the project directory
if [[ ${INTELLIJ} == "true" ]]; then
  cd ${OLDPWD}
fi

# Note that this works in IntelliJ 14, but not in 16.
# Change the shell path in IntelliJ's Tools > Terminal to:
# C:\cygwin64\bin\env INTELLIJ=true TERM=cygwin C:\cygwin64\bin\bash.exe --login -i

run_bash.bat

@echo off
set INTELLIJ=true
set TERM=vt100
set PATH="C:\cygwin64\bin";%PATH%

bash --login -i

REM This works in IntelliJ 16
REM Change the shell path in IntelliJ's Tools > Terminal to:
REM C:\path\to\this\script\run_bash.bat

I realize this is a bit of an older solution but I ran into an issue recently where installing chere -i -t mintty caused an issue with intellij setup using this configuration. The terminal will instead begin to start in the /home/user directory. To fix it, I had to comment out the .bashrc lines in this solution for the entire "if" statement including the "cd" statement. I then had to remove the "--login" and "-i" from the bash statement in line 6 of the run_bash.bat script.

Tools -> Terminal ->Application settings ->Shell Path: "c:\cygwin64\bin\sh.exe" -c "/bin/xhere /bin/bash"

Tools -> Terminal ->Application settings ->Shell Path: "c:\cygwin64\bin\sh" -lic "cd ${OLDPWD-.}; bash"

That last one worked for me in IDEA Ultimate 2018.2

Works for me as well 2018.3.4

Likewise, although I am using PhpStorm 2019.1.
I use zsh, so the command for me is "c:\cygwin64\bin\sh" -lic "cd ${OLDPWD-.}; zsh"
Works perfectly!

Tools -> Terminal ->Application settings ->Shell Path: "c:\cygwin64\bin\sh" -lic "cd ${OLDPWD-.}; bash"

Works like wonder

This worked for me in Intellij IDEA 2024:

C:\cygwin64\bin\bash -ilc 'cd -; exec bash'

The reply above me hung indefinitely.
