Continuous integration (CI Continuous integration/CD Continuous Deployment) The meaning of "team development" is actually the team development members in the R & D process continued Sex will be their work Integrate To a complete process , Typically each member integrates at least once a day , Each integration is through an automated build （ Including the compilation , Release , automated testing ） To verify , This enables early detection of integration errors . The main process of continuous integration is as follows ：

Sort out the R & D system , Development 、 test 、 The operation and maintenance process and Integrable parts include ：

• • Development ： Complete code writing or modification , Submit the code to the version library and package the project after merging , The parts that can be integrated are ：

• • • From the source code version management tool （ such as SVN、git） Pull the source code
    • Based on the version source code, use the compilation tool to complete the packaging （maven/gradle/ant etc. ）, Perform unit tests , Form applications that can be deployed or installed to run (war perhaps jar Bag, etc )

• • Operation and maintenance ： After compiling and packaging the deployable project , Deploy to various environments , The whole process can be continuously integrated

• • • Projects that will be deployable , By deploying the script process (shell、bat、docker Orders, etc ) Complete the deployment on the server environment

A lot of times , When developing your own continuous integration operation , At this stage, the project can be deployed normally , It's over .

• • test ： After the project is deployed to the test environment , Carry out smoke test （ Execute through automated tests ）, The integrable part is ：

• • • Execute the automated test script on the deployed test environment

Before continuous integration , Please make sure that each process can be executed separately ！

Next, let's say Windows Started under the server Jenkins Deployment in China Java Written in the course SpringBoot Take project operation as an example , Complete the operation of each part of the process .

Create build tasks

newly build Item

Fill in the name , choice freestyle project, Complete the creation of the build task .

Pull the source code of the project

Communicate with the developer to obtain the address and authentication method of the source code version warehouse , Make the relevant configuration .

If the authentication method needs to be configured , Click on credentials Add button under , You can quickly configure authentication methods , Take the private key configuration as an example ：

To his own git Private key file id_rsa（ It usually exists in the user directory by default .ssh In the folder ） Copy and paste the contents in .

Compile package project

According to the compilation and packaging method of the company's project , Select the corresponding compilation execution scheme .

For our project , Use maven Of clean package Command can complete unit test execution and packaging operations during the construction process , Form an executable jar.

P.S： Pay attention to the inspection items pom In the document packaging The element value is Jar.
