java.lang.ClassNotFoundException: org.springframework.core.ErrorCoded

Question

我在 spring 引导 shell 应用程序中使用以下依赖项。

<dependencies>

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter</artifactId>
      <version>2.0.0.RELEASE</version>
    </dependency>

    <dependency>
      <groupId>org.springframework.shell</groupId>
      <artifactId>spring-shell-starter</artifactId>
      <version>2.0.0.RELEASE</version>
    </dependency>

  </dependencies>

但是当我尝试 运行 应用程序时，我收到类似 'ClassNotFoundException: org.springframework.core.ErrorCoded'

的错误

Caused by: java.lang.ClassNotFoundException: org.springframework.core.ErrorCoded
    at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
