what does git gui output

Pushing to https://[email protected]/des1roer/newmining.git
To https://[email protected]/des1roer/newmining.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to ' https://[email protected]/des1roer/newmining.git '
hint: Updates were rejected because the remote contains work that you do
hint : do not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (eg, 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

Answer 1

You need to first get the changes you don't have - git pull. I don't know what it's called in NetBeans.
In error, in fact, everything is written.
