Maven some summary

1.maven installation and configuration   download Maven's installation package from Maven's official website, http://maven.apache.org/download.html.   Unzip it in the directory you want to place.   Then configure MAVEN's environment variables (m2_home), such as my maven installed under D:\Maven\apache-maven-3.0.3, then m2_home=d:\maven\apache-maven-3.0.3. If you want to use the MAVEN command in any directory, add the bin directory under the M2_home directory to the System environment variable path.   Use MVN-V to see the current version of Maven, indicating that the installation was successful.   NOTE: Before you install MAVEN, you must make sure that your computer has a JDK installed and that the Java environment is configured. 2. Set HTTP proxy   In some cases security considerations, the host cannot directly access the external network of the central warehouse, but instead of a security-certified proxy server, through the proxy server to access the Central warehouse.   How do I configure an HTTP proxy?   First after MAVEN is installed, MAVEN configuration information (Setting.xml) is placed in the m2_home/conf directory, and we can set up the proxy by modifying the file. However, if you modify the file directly, the impact will be global and not conducive to future upgrades. So we copy the file and put it under ~/.M2, then the file will overwrite the Setting.xml under m2_home/conf and only be valid for the current user. This allows each user to configure Maven to suit their preferences and needs. Specifically how to configure the HTTP proxy in Setting.xml, code into:  <proxies>       <proxy>       <id>my-proxy</id>       <active>true</active>       <protocol>http</protocol>
