老师您好，在搭建认证框架的时候使用较新版本的依赖会报错

Question

在父pom中配置如下
都是Spring 官网中的较GA新版本

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>io.spring.platform</groupId>
                <artifactId>platform-bom</artifactId>
                <version>Cairo-SR7</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-dependencies -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR1</version>
                <type>pom</type>
            </dependency>
        </dependencies>
    </dependencyManagement>

在执行mvn clean install的时候，会抛出如下错误

错误指向的子pom.xml文件如下：

<dependencies>
        <dependency>
            <groupId>com.learn.security</groupId>
            <artifactId>learn-security-core</artifactId>
            <version>${learn.security.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session</artifactId>
        </dependency>
    </dependencies>

我看了下Spring官网的cloud版本，G这个版本应该是2.0的 应该兼容之前的才对，所以想请问下老师这是为什么。

课程中使用的是Spring Boot 1.5,使用2.0版本可能会出现问题。还是用1.5版本的吧。

  老师 后续会继续会把课程更新到 springboot 2.0 以上的吗 或者项目更新
