How to open cygwin & execute bash in Eclipse? - eclipse

Question

I am trying to build my custom-commands in Eclipse.
This is Eclipse plugin which I am using: https://marketplace.eclipse.org/content/startexplorer
It looks like this (link to image):
Custom commands in Eclipse
I need eclipse variables in custom commands:
${resource_loc} , ${selected_resource_loc} , ${workspace_loc} , etc...
It should be something like this:
D:\cygwin64\bin\mintty.exe /bin/bash -l -c "cd ${workspace_loc}"
But mintty will close this window immediately. I need to execute command based on eclipse variable and go to bash interactive mode, without closing window.

Answer 1

To create a StartExplorer custom command, that opens a Cygwin terminal and
starts an interactive Bash shell in the filesystem location of the selected
resource, follow these steps:
Make sure to install chere
Cygwin package;
Install StartExplorer
Eclipse plugin;
In Eclipse Preferences for plugin StartExplorer, create a new custom
command:
Command: D:\cygwin64\bin\mintty.exe -e /bin/xhere /bin/bash
"${selected_resource_loc}"
Enabled for Resources: yes
Name for Resources Menu: Cygwin Bash Here
Resource Type: Folders
Alternatively to steps 2 and 3, if you don't care about context-menu entry, no
need to install the StartExplorer plugin.
Eclipse Extenal Tools Configuration standard feature will do the trick.
In Run > Extenal Tools Configuration, create a new Program:
Name: Cygwin Bash Here
Location: D:\cygwin64\bin\mintty.exe
Arguments: -e /bin/xhere /bin/bash "${selected_resource_loc}"
Basically, the xhere script (part of chere package) performs the following steps:
indicate to the login shells not to cd $HOME (export CHERE_INVOKING=true, which is checked for in /etc/profile);
change to the directory passed as 2nd argument (cd "$2");
Execute the shell passed as 1st argument as a login shell (exec -l $1).
Note: if you replace /bin/bash with /etc/passwd, the current user's login shell read from /etc/passwd is used instead of bash.
