我已将项目更新为使用springboot 2.3.0，并尝试使用默认的springboot gradle任务bootBuildImage构建docker映像。
该项目是一个简单的其余项目，分为两个部分：-接口定义和接口实现。在使用Dockerfile生成映像时，所有这些都在尝试，但是我正在尝试使用新功能。
我没有更改任何配置，也没有添加任何自定义项。我只是普通的任务，但遇到了以下问题。

这似乎是build cache related（构建缓存已损坏）。您的构建日志显示已使用的构建缓存：
...
> Executing lifecycle version v0.7.5
> Using build cache volume 'pack-cache-defc64ac2d6d.build'
由于Spring Boot Gradle插件（与spring-boot-maven-plugin相同）是Paketo.io的抽象，所以它是pack CLI，它使用Docker进行本地构建，因此您应该能够使用以下命令找到构建缓存卷pack-cache-defc64ac2d6d.build
docker volume ls
这给出了类似的内容：
$ docker volume ls
DRIVER VOLUME NAME
local bellsoft-jre-config
local pack-cache-defc64ac2d6d.build
local pack-cache-defc64ac2d6d.launch
local spring-cloud-config
现在分别删除构建缓存（docker volume rm pack-cache-defc64ac2d6d.build-或仅通过以下方式删除其他容器未使用的所有本地Docker卷：
docker volume prune
现在您的构建应该再次运行。
