****/pom.xml

Problems:
Unresolved plugin: 'org.apache.maven.plugins:maven-compiler-plugin:3.1'

Unresolved plugin: 'org.apache.maven.plugins:maven-surefire-plugin:2.12.4'

Unresolved plugin: 'org.apache.maven.plugins:maven-install-plugin:2.4'

Unresolved plugin: 'org.apache.maven.plugins:maven-deploy-plugin:2.7'

学习了这篇笔记后成功解决该问题，笔记链接如下：

• 步骤一：在pom.xml里键入dependencies里的代码（代码已附在后面）
• 步骤二：等待包的下载
• 步骤三：点击下图中的Reload Project
• 步骤四：等待下载完成，报错解除
  

    <dependencies>
    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <type>maven-plugin</type>
    </dependency>

    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-install-plugin</artifactId>
        <version>2.4</version>
        <type>maven-plugin</type>
    </dependency>

    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-deploy-plugin</artifactId>
        <version>2.7</version>
        <type>maven-plugin</type>
    </dependency>

    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.12.4</version>
        <type>maven-plugin</type>
    </dependency>

    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-site-plugin</artifactId>
        <version>3.3</version>
        <type>maven-plugin</type>
    </dependency>

    </dependencies>

补充：

1. 在dependencyManagement中无法定义
2. 如下图中的version3.2报错时，需要在dependency中重新定义

在dependency中重新定义：

    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <type>maven-plugin</type>
    </dependency>
