Git pre-push hook executed twice

Does it happen only when you build in IntelliJ IDEA or when you run Maven build in the terminal as well?

Hi !

Yes, it happens only when I build/push in Intellij IDEA. From the command line, it is correctly executed :

bbo@work ~/B/project>git push origin xxx-branch

Are you sure it is the hook which is executed twice? Can it be possible that one of these `mvn clean install` commands are issued from IDEA Maven Integration? If you're not sure, to diagnose this you can add some output line to the hook that would clearly indicate that it it a hook which is being executed. 

At any case, please reproduce the issue and attach idea.log file.

The same is happening to me, if a use the UI the pre-push hook is executed twice. The second time, a modal window appears asking for credentials.

I reproduce it each time while using the UI. Running git push in the terminal executes pre-push only once.

I can provide more info if needed.

Right now I have this version:

What exactly does the hook do? Can you share it?

Also, what is the difference between output when you push via terminal vs inside IDE? Can you share both examples? 

Sure, pre-push hook:

#!/bin/sh
# Ejecuta los tests de Maven
echo "Running tests pre-push"
mvn test -DargLine="-ea -Duser.timezone=UTC"
# Verifica si los tests se ejecutaron correctamente
if [ $? -ne 0 ]; then
  echo "Test failed! Chech errors before trying again."
  exit 1
fi
echo "Test Pre-Push Successful!"
exit 0

Using IDE, after commit I use this UI:

After clicking Push:
14:54:40.080: [backend] git -c credential.helper= -c core.quotepath=false -c log.showSignature=false push --progress --porcelain origin refs/heads/develop:develop
Running tests pre-push
...
Test Pre-Push Successful!

14:58:57.776: [backend] git -c credential.helper= -c core.quotepath=false -c log.showSignature=false push --progress --porcelain origin refs/heads/develop:develop

It presents this modal window, because it is trying to push again

If  I introduce the token, it continues and runs again pre-push hook: Running tests pre-push

When running on terminal, just running the same command git -c credential.helper= -c core.quotepath=false -c log.showSignature=false push --progress --porcelain origin refs/heads/develop:develop

runs pre-push hook only once.

Are you using git lfs?
