Question

我正在运行Spring应用程序并收到以下错误：$ conda-build pybedgraph ... An HTTP error occurred when trying to retrieve this URL. HTTP errors are often intermittent, and a simple retry will get you on your way. Could not download https://pypi.io/packages/source/p/pybedgraph/pybedgraph-0.5.35.tar.gz

一个类似的问题已经回答in this question。在接受的答案中，Gergely Bacso指出问题是Spring Boot的多个版本。

堆栈跟踪列出了java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.websocket.WebSocketAutoConfiguration$TomcatWebSocketConfiguration.websocketContainerCustomizer中发生的错误，当我尝试单击它时，会提供两个不同版本的Spring Boot，如下图所示：

我的问题是：1）这就是为什么我遇到此异常吗？ 2）如果是这样，我如何摆脱多余的版本？（或者，如果没有，还有其他想法为什么会这样？）

作为参考，这是我的pom.xml

SpringBootCondition.java

这是我的应用程序。yml：

当我运行Maven依赖关系树时，我看到以下内容：

spring:
  datasource: #TODO replace application.yml with an xml or java config file
    url: jdbc:${DBURL} #localhost/taskorchard
    username: ${DBUSER}
    password: ${DBPASSWORD}
  tomcat:
    max-wait: 20000
    max-active: 50
    max-idle: 20
    min-idle: 15
  jpa:
    hibernate:
      ddl-auto: validate
    properties:
      hibernate:
        dialect: org.hibernate.dialect.PostgreSQLDialect
        format_sql: true
        id:
          new_generator_mappings: false

server:
   port: 8080 # This is the default port anyway, but you can change it here

security:
  jwt:
    token:
      secret-key: secret-key
      expire-length: 300000 # 5 minutes duration by default: 5 minutes * 60 seconds * 1000 miliseconds

UserController:
  signin: Authenticates user and returns its JWT token.
  signup: Creates user and returns its JWT token
  delete: Deletes specific user by username
  search: Returns specific user by username
  me: Returns current user's data

好的，我知道了。我去了File-> Project结构，在那里看到spring-boot-starter-test.2.2.0。当我删除它时，起初我不知道发生了什么，因为我以前排除了log4j.logger-classic模块，因为与log4j版本的冲突不同，所以当程序正确运行时我看不到日志，不知道它正在运行。

如果您有类似的问题，并且无法解决此问题，我会尽力帮助您。
