C:\20170801\GitProject>Displaying BUILD SUCCESS means that the project is successfully built! ! !
The directory structure of the built java project is as follows:
Under the development directory src/main/java/com/sjmz/javademo, a default App class file is created with the following content:
package com.sjmz.javademo;
/**
* Hello world!
*
*/
public class App
{
public static void main( String[] args )
{
System.out.println( "Hello World!" );
}
}Under the test directory src/test/java/com/sjmz/javademo, a default AppTest class file is created with the following content:
package com.sjmz.javademo;
import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;
/**
* Unit test for simple App.
*/
public class AppTest
extends TestCase
{
/**
* Create the test case
*
* @param testName name of the test case
*/
public AppTest( String testName )
{
super( testName );
}
/**
* @return the suite of tests being tested
*/
public static Test suite()
{
return new TestSuite( AppTest.class );
}
/**
* Rigourous Test :-)
*/
public void testApp()
{
assertTrue( true );
}
}In actual project development, we usually have configuration files, such as log4j.properties, so we also need to manually create src/main/resources (storage configuration files used in project development) and src/test/resources (storage test Configuration file), as follows:
2. Description of the pom file in the project
Projects built through Maven will have a pom.xml file in the project root directory, which is the core of Maven.
1) pom means project object model
2) pom.xml contains project construction information, including project information, project dependencies, etc.
3) pom.xml file can be inherited, in large projects, sub-module pom.xml Generally inherited from the pom.xml of the parent module
The content of pom.xml is as follows:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.sjmz.javademo</groupId>
<artifactId>javademo</artifactId>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
<name>javademo</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>Description of the node elements of the pom.xml file:
<project> The top-level node of the pom file
<modelVersion> object model version, for Maven2 and Maven3, it can only be 4.0.0
<groupId> the identifier of the project creation organization, generally the domain name The reversed writing of
<artifactId> defines the unique identifier of the project under the identifier of the organization to which it belongs. There can be multiple projects under one organization.
<version> The version of the current project, SNAPSHOT, means a snapshot version, which is
packaged in <packaging> under development There are jar, war, ear, etc.
<name> project name
<url> project address
<properties> property configuration, such as: <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<dependencies > Build the jar that the project depends on
Among them, a project coordinate is uniquely determined by groupId, artifactId and version.

C: \ Users \ Administrator \ .m2 \ repository \ com \ sjmz \ javademo \ javademo \ 1.0-SNAPSHOT \ javademo-1.0-SNAPSHOT.jar
5. Run the jar package
Run the command java -cp target\javademo-1.0-SNAPSHOT.jar com.sjmz.javademo.App
C:\20170801\GitProject\javademo>java -cp target\javademo-1.0-SNAPSHOT.jar com.sjmz.javademo.App
Hello World!
C:\20170801\GitProject\javademo>Fourth, publish local projects to Gitee
1. Create a warehouse in Gitee
Enter the warehouse name, which is the same as the local project name
Select language-Java
Add .gitignore-Eclipse ( Generally we always have some files that do not need to be managed by Git, and we don't want them to always appear in the untracked file list. Usually they are automatically generated files, such as the target directory generated by maven, such as IntelliJ IDEA editor Idea directory generated by the compiler, such as log files, or temporary files created during compilation. We can create a file named .gitignore to list the file patterns to be ignored. )
Add open source license-Apache v2 License
Get the gitee address of the project:
2. [Prerequisite-git client installed] Enter the root directory of the local project javademo, right-click in the blank space, and select "Git Bash here"
Run the git clone https://gitee.com/sjmz30071360/javademo.git command
