1. Preparation
1. Make sure that jdk7.0 or above has been successfully installed on the computer
2, win7 operating system
3. maven installation package download address: http://maven.apache.org/download.cgi
2. Unzip the Maven installation package
Download the latest Maven version from the above address, extract it to the specified directory (here according to your own needs), I extracted it to the D:\install\maven\apache-maven-3.5.0 directory, which contains bin, lib
conf, etc. folder.
3. Configure Maven environment variables
In My Computer-------Properties-------Advanced System Settings---------Environment Variables---------System Variables------ --new
Variable name: M2_HOME
Variable value: D:\install\maven\apache-maven-3.5.0
Find the Path and add it at the end of the environment variable value: ;%M2_HOME%\bin; //Pay attention to the semicolon before
Fourth, check whether the environment variables of jdk and maven are configured successfully
Open the dos window and run the command mvn -v, the information shown in the following figure appears, indicating that the installation is successful;
5. Modify the local warehouse location (if you do not want to modify the local warehouse location, this step can be omitted)
Maven will place the downloaded class library (jar package) in a local directory (by default, maven's local repository is located in C:\My Documents\.m2.\repository ), if you want to redefine this The location of the directory needs to modify the configuration of the Maven local warehouse:
1. Create a folder in your favorite location, the location I created here is (F:\Maven\repo)
2. Find the conf folder in the directory where Maven is installed, find the settings.xml file in the folder, copy the settings.xml file and put it in F:\Maven , as shown in the following figure:
3. Modify the settings.xml file as shown below:
4. Find the conf folder in the directory where Maven is installed, find the settings.xml file in the folder, and change the default warehouse location as shown below: (note that the settings.xml in both places must be modified)
According to this configuration, Maven will save the downloaded class library to F:/Maven/repo.
5. Experiment to see if what we just did has any effect, console input: mvn help:system
After executing this command, there will be many files under F:/Maven/repo. These files are the files downloaded by maven from the central repository to the local repository.
