Jenkins Workspaces

• When we run a jenkins project, it needs some folder to
  • clone the git code
  • perform build or other actions
• This folder is called as workspace
• Lets create a new project
  
  
  
  
• This project should clone the git and execute the build steps
• Lets look into where this project is stored and how
  • Project definition is stored in ~/Jobs/<project-name>
  • config.xml file will have the steps defined in the job written as xml file
    
    
    
• Now lets try to build the job (Run the pipeline)
  
• In ~/Workspaces/<project-name> the code of git will be cloned. This folder will be pwd (present working directory) when the job is executing
  

Building the code, Packaging the code

• As discussed in the class the package is the format that will be used to run the application in enduser environment
• Building the code: Converting the code into
  • Executable that os understands (C,C++)
  • Bytecode that runtime understands (Java, .net)

Exercise

• what is makefile and how is used to build simple C program
• What is ANT and how did it help in building java code.
