This document provides an overview of source control and version control using Git and GitHub. It discusses setting up projects with Maven and developing projects locally before pushing changes to GitHub repositories. The key points covered include: setting up source control with Git, forking and cloning repositories on GitHub, making changes locally and pushing updates via pull requests. Maven is also introduced for building Java projects and managing dependencies in an automated way.

2. 1. A very brief introduction to source control
◦ What is source control
◦ Why we need it
◦ How to manage (commands can be used/ things needs
to be considered before commit)
2.
◦ “Hello Jaffna” Compile it and run using command line
◦ Development tools and build tools
◦ Create project structure with specified archtype
◦ Simple maven targets
◦ Build and run using maven

3. 3.
◦ create account and repository on github
◦ Install and setup github
◦ fork and clone project
◦ pull/push request
4.
◦ Fork and clone yshool
◦ Pull yschool to local repo
◦ Clean and deploy using maven
◦ Make some change push it back

4.  tracks and provides control over changes to
source code
 Examples :
• Github
• SVN(Subversion)
• CVS
• etc

5.  track files
 Periodically commit
 history will help to collaborate with other
developers
 merge between other developers
 compare and revert with previous version of
project/individual files

6.  Getting and Creating Projects
 Basic Snapshotting
 Branching and Merging
 Sharing and Updating Projects
 Inspection and Comparison

7.  Make sure that you are working on the latest
version of a file.
 Check out only what you need.
 Check in promptly.
 Write good check-in comments.

8.  public class AppTest{
public static void main(String [] args){
System.out.println("Hello Jaffna!");
}
}
 Compile using command line
• Javac AppTest.java
• Java AppTest

9.  Build process is repetitive process where
programmer builds the project again and
again to test the changes in the project code
 Build tools automate the repetitive process
and allows the programmer to concentrate on
the project development
 Building in a single click

10.  Dependency management
 Versioning
 Compile Java code, build jars
 Execute tests and report results, fail build on
failed tests
 Run quality-check tools (PMD, Findbugs,
Checkstyles)
 File generation (XmlBeans, Xsl, Velocity,
AspectJ)
 Property expansion / token substitution

11.  software project management and
comprehension tool
 Based on the concept of a project object
model (POM),
 Maven can manage a project's build,
reporting and documentation from a central
piece of information.

12.  In Maven, an archetype is a template of a
project which is combined with some user
input to produce a working Maven project
 mvn archetype:generate -
DarchetypeArtifactId=maven-archetype-
webapp -DgroupId=package-name -
DartifactId=project-name

13.  Project – Top level
 modelVersion - what version of the object model
this POM
 groupId - unique identifier of the organization
 artifactId - unique base name of the primary
artifact/context
 packaging - package type
 version
 name - display name
 url - where the project's site can be found
 description - basic description of your project

15.  mvn compile
 mvn test
 mvn install
 mvn package
 mvn clean
 http://maven.apache.org/guides/getting-
started/index.html#How_do_I_compile_my_a
pplication_sources

16.  git is a distributed version control system
 Is a place where we store our publicly
available source code for client libraries.

17.  Getting and Creating Projects
• Init
• clone
 Basic Snapshotting
• add
• status
• diff
• commit
• reset
• rm, mv

18.  Branching and Merging
• branch
• checkout
• merge
• log
• tag
 Sharing and Updating Projects
• fetch, pull
• push
• remote
 Inspection and Comparison
• log
• diff

19.  Set Up Git
 Add git plugin

 Create A Repository
 Fork A Repository

20.  Created a maven project
 Setup git
 Push that to your account
 Fork and clone and existing project
 Send fetch & pull requests
