我正在尝试将一个简单的Spring Boot Web应用程序部署到Pivotal Cloud代工厂，但是当我执行cf push时，我的日志中出现以下错误

java.lang.ClassNotFoundException: org.springframework.context.ApplicationContextInitializer

这是我的pom.xml

同一个应用程序部署在我的本地主机上，我没有问题构建战争。有什么想法吗？

正如Andy Wilkinson所指出的，这是Spring Boot 1.4和java_buildpack之间不匹配的问题。它可以通过明确提到java_buildpack的URL来解决：

$ cf push -b https://github.com/cloudfoundry/java-buildpack.git …

Answer 2

由于SSL握手异常，似乎jar在maven构建期间没有下载。出于某种原因，尽管丢失了jar，我的构建并没有失败。通过在mvn clean install期间启用调试来找到它

Spring Boot - java.lang.ClassNotFoundException：org.springframework.context.ApplicationContextInitializer
