Graphic tutorial on maven environment configuration in Java

Because I want to build the project on maven, I did some research. Let’s talk about my process of building the maven project.

1. Download maven

Click to enter http://maven.apache.org/download.cgi?Preferred=http%3A%2F%2Fmirror.bit.edu.cn%2Fapache% 2F, click apache-maven-3.5.0-bin.zip to download.

2. Deploy maven

Computer right-click properties

Advanced System Settings--"System Properties--"Environment Variables--"Create MAVEN_HOME and configure the variable as the local maven address

Enter the path environment and add at the end of the variable value ;%MAVEN_HOME%\bin;

Test whether the maven configuration is successfulOpen the command line window and enter mvn -v. If there is maven version information output, it proves that the configuration is successful. Otherwise, please check your own configuration Are the paths etc. correct?

Note: Before installing maven, please ensure that the JDK has been installed and its environment variables have been successfully configured.

3. Modify the maven local warehouse

Introduction: The local warehouse is a buffer and subset of the remote warehouse. When you build a Maven project, you will first Find the resource from the local repository. If it is not available, Maven will download it from the remote repository to your local repository. This way you don't need to download it remotely the next time you use it. If the jar package version you need does not exist in the local warehouse and does not exist in the remote warehouse, Maven will report an error when building. This situation may be that the new version of some jar packages has not been updated in the Maven warehouse in time

The default address of maven is found in the m2\repository folder under C:\Users\Administrator. You can modify the default address by modifying setting.xml

Operation:

1. Find the setting.xml file in the maven conf folder

2. Add a new one in the setting.xml file (indicating that the address of the local warehouse is: D:\m2\repository)

<localRepository>D:\m2\repository</localRepository>
3.将setting.xml复制一份到D:\m2\repository目录下
四、修改eclipse中maven配置
打开eclipse点击windows->preferences->maven->installations下add一个已经安装到D:\maven\目录下的maven，如：D:\maven\apache-maven-3.3.3，并勾选此新加项。并点击下面的browse按钮打开maven的全局配置文件,如：D:\maven\apache-maven-3.3.3\conf\setting.xml
五、修改maven默认jdk版本
其实http://www.cnblogs.com/Hxinguan/p/6132446.html这篇文章已经讲的很详细了，在这里我只简单的讲一下我的操作
1.在maven的conf文件夹下找到setting.xml文件
2.在setting.xml文件下添加以下代码

<profiles>  
<profile>    
<id>jdk-1.8</id>     
<activation>          
<activeByDefault>true</activeByDefault>          
<jdk>1.8</jdk>      
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile>
<profiles>

3.右键maven项目--》maven--》updateproject即可
