Let’s get Project 0!

• Open the class BitBucket address:– https://

bitbucket.org/cmsc433_spring2012/project0

• Fork Project 0– Don’t forget to concatenate your Directory ID to

your forked repository!

• Now you’re… almost ready to get the project skeleton code on your machine! – Before you can do it, you have to get a Git client

first…


7

Git

• Download a Git client. Tutorials for all:– Windows 7:

10

Git (Windows users)

• Some tricks– Set the Git home directory (by default, it’s C:\

Users\<username>):• Create a directory with this purpose (for example, D:\

CMSC433\Git)• Create a HOME environment variable


11

Git (Windows users)

• Some tricks– Set up your name and email (so they appear nicely in

BitBucket when you make changes to your repository)• In Git Bash, type the commands:

– git config --global user.name “<first name> <last name>“– git config --global user.email “<your_email>@umd.edu“

– (notice that Git creates a file called .gitconfig with the information you provided)

• Now you’re… almost ready to get the project skeleton code on your machine! – In the repository page, look for the HTTPS link…


13


• Now you’re… almost ready to get the project skeleton code on your machine! – In the repository page, look for the HTTPS link…– Copy it, and paste it in the Git command window.

Git will create a clone of the repository on your local machine…• … but how annoying: you need to supply the password

for your account. Can we get rid of that?


14

Git (Windows users)

• Let’s create a default ssh identity.– Run the command: ssh-keygen


15

Git (Windows users)

• Let’s create a default ssh identity.– Create a config file (indentation is important)

(~/.ssh/config):

– Restart your Git bash terminal


16

Git (Windows users)

• Let’s create a default ssh identity.– Let BitBucket know about your ssh identity:• In your Account Settings page, look for the SSH keys

section


17

Git (Windows users)

• Let’s create a default ssh identity.– Let BitBucket know about your ssh identity:• In your Account Settings page, look for the SSH keys

section• Open the public key generated by ssh-keygen. (For

example, D:\CMSC433\Git\.ssh\id_rsa.pub)• Paste the contents into the text box, and click Add Key


18


• Now you’re… almost ready to get the project skeleton code on your machine! – In the repository page, look for the HTTPS SSH link…– Copy it, and paste it in the Git command window. Git will

create a clone of the repository on your local machine!

• Let’s import Project 0 in Eclipse! – File > Import > General > Existing Projects into

Workspace• Or… use magic: CTRL+3


20



Workspace– Select root directory:• (point to the path

where you clonedthe project)


21



Workspace– Select root directory:• (point to the path

where you clonedthe project)

– Finish!


22


• Let’s import Project 0 in Eclipse! – There’s a nicer way to do it:• Window > Open Perspective > Other… > Git Repository

Exploring• Or… use magic: CTRL+3


23



Exploring• Add an existing Git repository


24



Exploring• Add an existing Git repository• Point to the location of your project 0 clone, and hit

Search:

Exploring• Add an existing Git repository• Point to the location of your project 0 clone, and hit

Search. Select your clone, and click ok.


26


• Let’s import Project 0 in Eclipse! – There’s a nicer way to do it (cont’d):• Import project into your workspace


27


• Let’s import Project 0 in Eclipse! – Actually… there’s an even nicer way to do it:• Instead of using Git Bash, you could do everything from

Eclipse!• File > Import… > Git > Projects from Git > Clone…• In the URI field, paste the SSH URI from BitBucket.• In the protocol field, select SSH

• Let’s import Project 0 in Eclipse! – Actually… there’s an even nicer way to do it:• Choose a Local Destination• Select the Git repository to import


31


• Let’s import Project 0 in Eclipse! – Actually… there’s an even nicer way to do it:• Choose a Local Destination• Select the Git repository to import• Done!


32


• Let’s import Project 0 in Eclipse!– Note: Whenever you import a Git project to

Eclipse via the Git UI, you get some additional Eclipse functionality, via the Team menu:


33

Let’s solve Project 0!

• Taking a look at Project 0 (ParallelSum)– Run test– Implement the test method:

ParallelAdderTest.testTotalSum() – Run test again…– Implement ParallelAdderWorker.run()– Run test again…– Implement ParallelAdderWorker.getPartialSum()– Run test again…


34

Let’s solve Project 0!

• Submit your solution:– Run git add on your modified files. (in Git Bash)• Or use the Eclipse Team menu

– Run git commit –m “…”– Run git push– See your changes online:

https://bitbucket.org/<user>/project0-<dirId>
