Maven installation tutorial and maven tutorial

I. Preparations

1. Confirm that JDK and later are successfully installed on your computer.

2. win10 Operating System

3. maven installation package: http://maven.apache.org/download.cgi

Ii. decompress the Maven installation package

Download the latest Maven version from the above address and decompress it to the specified directory (based on your needs). I decompress it to the D: \ install \ maven \ apache-maven-3.5.0 directory, contains bin and lib

Conf and other folders.

3. Configure Maven Environment Variables

In my computer ------- properties ------- advanced system settings --------- environment variable --------- system variable -------- new

Variable name: M2_HOME

Variable value:D: \ install \ maven \ apache-maven-3.5.0.

Find the Path and add it to the end of the environment variable value:; % M2_HOME % \ bin; // note the semicolon before

4. Check whether the environment variables of jdk and maven are successfully configured.

Open the dos window and run the command mvn-v. the information shown in shows that the installation is successful;

 

5. Modify the location of the local repository (skip this step if you do not want to modify the location of the local repository)

Maven places the downloaded class library (jar package) to a local directory (By default, maven's local repository is located in C: \ My Documents \. m2. \ repository.), If you want to redefine the location of this directory, You need to modify the configuration of the Maven local repository:

1. Create a folder in your favorite location. The path created here is (F: \ Maven \ repo)

2,Find the conf folder in the Maven installation directory, find the settings. xml file in the folder, and copySettings. xml fileStored inF: \ Maven, As shown in:

3. Modify the settings. xml file, as shown in:

4. Find the conf folder in the Maven installation directory, find the settings. xml file in the folder, and change the default repository location, as shown in Figure :( note that the settings. xml file must be modified in both places)

Based on this configuration, Maven will save the downloaded class library to F:/Maven/repo.

5. Experiment what we just did does not work. On the console, enter mvn help: system.

 

After executing this command, many files will appear under F:/Maven/repo. These files are downloaded from the central repository of maven to the local repository.
