IntelliJ Idea gpg failed to sign data

Question

i can't commit with IntelliJ and an activated gpg in config. Currently I can only do this with git bash manuel. I use windows and i found a lot of informations for OSX but that didn't helped me.

How can I use VCS in IntelliJ without doing anything about git bash?

This is the error from IntelliJ when i try to commit something.

11:52   Commit failed with error
        0 files committed, 1 file failed to commit: update
        gpg failed to sign the data
        failed to write commit object

Answer 1

IDE is not a terminal and cannot handle the prompt issue by gpg on the command line.

As a workaround, you could create a wrapper and tell git to use it as gpg app.

Wrapper code:

# file /home/user/gpg-no-tty.sh
#!/bin/bash
/usr/bin/gpg --batch --no-tty "$@" 

and then set your git config for the repo where you want to gpg sign commits:

[gpg]
        program = /home/user/gpg-no-tty.sh

In Windows + (IntelliJ / AndroidStudio), your global git config should look like this:

user.name=<username>
user.email=<email>
user.signingkey=<key>
commit.gpgsign=true
gpg.program=<path to gpg.exe>
