GIT: Pushing a remote branch with a different local branch name

Usually, when you are pushing like git push origin master, your remote branch name and local branch is same i.e, master

But if you're having a different branch name locally for your remote branch 'master

$ git push origin localbranchName:remotebranchName

example: git push origin testlocal:master

Git force merge

Here is my scenario - I've development and release branches. And I want to merge my changes from development to release branch and if any conflicts during merge and I want to overwrite with the development branch changes.

$ git checkout release  => switch from development to release branch
$ git merge -X theirs development  => merge changes from development to release branch

Showing progress dialog using Eclipse jobs API

Below piece of code shows how can we run the eclipse jobs interactively by showing eclipse progress dialog using Eclipse Jobs API.

Job installationJob = new Job("Creating a new creating catalog...")

{

@Override

public IStatus run(IProgressMonitor monitor)

{

try

{

monitor.beginTask("creating catalog...", 10);

//do your task here

}

finally

{

monitor.done();

}

return Status.OK_STATUS;

}

};

installationJob.setPriority(Job.INTERACTIVE);

//This is alternative to the installationJob.setUser(true);
//sometimes setUser(true) doesn't show up the progress dialog, in those cases below piece of code can be used.

PlatformUI.getWorkbench().getProgressService()

.showInDialog(Display.getDefault().getActiveShell(), installationJob);

installationJob.schedule();
