2. Create a folder under any directory, under which you create a pom.xml file, a bat batch script;
4. Select the bat batch script right-click Edit and copy the following:
   

    Call Mvn-f pom.xml dependency: Copy-dependencies@Pause

5. Pom.xml does not need to be as complex as the actual project, the example is as follows (<?xml version= "1.0"?> must be in the first line of text):

   <?XML version= "1.0"?><Projectxmlns= "http://maven.apache.org/POM/4.0.0"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelversion>4.0.0</modelversion>    <groupId>Temp.download</groupId>    <Artifactid>Temp-download</Artifactid>    <version>1.0-snapshot</version>     <Dependencies><!--what jar packages need to be downloaded add the rest of the dependencies without care -        <Dependency>            <groupId>Mysql</groupId>            <Artifactid>Mysql-connector-java</Artifactid>            <version>5.1.34</version>        </Dependency>    </Dependencies></Project>
