intellij idea的maven下载不到内容怎么办？

Question

找个地址明明是从maven的网站复制下来的，怎么下载不了呢，

<!-- http://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-jpa -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
            <version>${spring.boot.version}</version>
        </dependency>

如图，第一个都可以下载的...

完整的pom.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns = "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>DemoOne</groupId>
    <artifactId>DemoOne</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <spring.boot.version>1.3.5.RELEASE</spring.boot.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>${spring.boot.version}</version>
        </dependency>

        <!-- http://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-jpa -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
            <version>${spring.boot.version}</version>
        </dependency>

        <!-- http://mvnrepository.com/artifact/mysql/mysql-connector-java -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.8</version>
        </dependency>

    </dependencies>

</project>

Answer 1

我是初学者，没有用过你的这种写法，但是 intellij idea在第二个

<version>${spring.boot.version}</version>

有报错，你看一下报错信息再做一下修改吧

Answer 2

已经解决，换了默认的maven就行了。
