Life and death can not solve the eclipse Maven project to create the ultimate method - (maven comes with installation tutorial)

Recently maven project I was head of the whole big, what it feels like, that is, before you think it is a soft, but slowly becomes your answer, for this is the one I love into a dead end, it must Sa (Country love recently seen a lot! haha)

Step.1 First we have to install maven, then, need to go to the official website to download the source files

maven official website paper airplane to go from ~

Then click on the left side of the interface will download to the download page


after download is a compressed package, unzip it
** We need to change a configuration file into a local repository is the path, there is the address of a remote warehouse, concrete local warehouse, the concept of the two, I posted part in this diagram,

configure this

then

<!-- 阿里云中央仓库 -->
<mirror>
	<id>nexus-aliyun</id>
	<mirrorOf>central</mirrorOf>

	<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>

Finally Ctrl + S (Be sure to save !!!!)

Step.2 configuration environment variable

Open My Computer ---- "---- Right Properties> Advanced System Settings ----> Environment Variables -" lower-right corner of New

Finally, click ApplyAndClose

Step.4 Maven project

New-----》Other

Click Next

Take some time to download the environment after the finish, this time after another error on a (which many students are being given)

For example: This error is essentially a network problem, how to solve, find the location of the widget

Delete this folder, then go right project project ----> maven Options ----> Project and Update
(if it is reported that this was wrong, it has been deleted, has been update, and he has been a never-ending struggle down)
, etc. After a while, the project is created, it is like this
standard Maven project format

this time Maven project you're done, we can write a helloworld
there is also need to pay attention to step

web.xml file contents

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>此处为你的项目ID</display-name>
</web-app>

Create a new html file in webapp, we can access it (start Tomcat)

So far, maven project and you're done ~ ~ ~

Add this: Some update after students have become a problem jdk 1.5, we can click on POM
, add the following xml file

attached below Source

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.7.0</version>
                <configuration>
                    <source>1.8</source>  // 这里写你的jdk版本
                    <target>1.8</target> // 这里写你的jdk版本
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>
