我使用docker运行我的spring boot应用程序和intellij idea。我可以构建我的应用程序的映像，但是，如果运行映像，我将得到如下消息：

Failed to deploy 'centre Image id: some/centre:latest': java.lang.NullPointerException

几天前，我可以使用相同的操作来运行我的docker映像，它只是一个spring启动应用程序。现在，我使用maven来构建我的项目，因此，单个应用程序是我项目的一个模块，在那之后，我遇到了问题。
我的相关文件如下：
dockerfile文件：

FROM java:8
VOLUME /tmp
ADD study-info-0.0.1-SNAPSHOT.jar app.jar
EXPOSE 80 443
ENTRYPOINT [ "java", "-jar", "/app.jar" ]
