A. Download

https://maven.apache.org/download.cgi

II. Installation

Unzip apache-maven-3.6.1-bin.zip

The bin file with mvn command folder to the PATH environment variable (similarly configured java environment variables)

In cmd Input: mvn -v to confirm the following results

III. Create a project

In cmd, enter:

mvn -B archetype:generate -D archetypeGroupId=org.apache.maven.archetypes -D groupId=com.mycompany.app -D artifactId=my-app

The src/main/javadirectory contains the source code for the project, the src/test/javadirectory that contains the test source pom.xmlfile is a project object model of the project or POM.

Integrated IDEA, marked the district to replace its own download

IV. Project Inheritance

1

• |-- my-module
• | `- pom.xml
• `- pom.xml

1. <project>
2. <parent>
3. <groupId>com.mycompany.app</groupId>
4. <artifactId>my-app</artifactId>
5. <version>1</version>
6. </parent>
7. <modelVersion>4.0.0</modelVersion>
8. <groupId> com.mycompany.app </ groupId> ( overlapping portion )
9. <artifactId>my-module</artifactId>
10. <version> 1 </ version> ( overlapping portion )
11. </project>

  Sub-module may be removed redeclaration parent direct reference module

1. <project>
2. <parent>
3. <groupId>com.mycompany.app</groupId>
4. <artifactId>my-app</artifactId>
5. <version>1</version>
6. </parent>
7. <modelVersion>4.0.0</modelVersion>
8. <artifactId>my-module</artifactId>
9. </project>

• | - My - Modules
• | | | `- pom.xml
• `- parents
• `- pom.xml

1. <project>
2. <parent>
3. <groupId>com.mycompany.app</groupId>
4. <artifactId>my-app</artifactId>
5. <version>1</version>
6. <relativePath>../parent/pom.xml</relativePath>
7. </parent>
8. <modelVersion>4.0.0</modelVersion>
9. <artifactId>my-module</artifactId>
10. </project>

relativePath name suggests, it is from the module pom.xmlrelative to the path of the parent module pom.xml.

V. everyday use and conceptual understanding

1:

生命周期clean、validate、compile、test、package、verify、install、site、deploy.

Development in general can be performed by the following sequence

clean: In addition to the project file and compile local warehouse packed files (ie local install file)

compile: That file is compiled java project, compiled and stored in the project directory

install the package code stored in the local maven repository available for other projects depend on local use

Note: Package Penalty for is to hit the jar next target of this project, while install the target of a jar attached to a local warehouse for other projects.

SNAPSHOT version is the final 'publication' development 'versions of the previous version. SNAPSHOT version than its "older."
