java - 无法在 Openshift 中部署 Spring Boot 应用程序

Question

我正在按照以下步骤运行我的 Spring Boot 应用程序:https://github.com/debasen/springboot-demo.git在 Open shift :

1. 将 Red Hat OpenJDK8 添加到我的项目中。

2.下一步 3.添加命中库

完成后。我在构建时收到以下日志:

由于在构建时没有创建 jar，部署失败。而示例存储库中的项目 https://github.com/jboss-openshift/openshift-quickstarts工作正常。我尝试使用 Heroku 来托管我的应用程序。它在 Heroku 中运行良好.但不在 Openshift 工作。请告诉我我错过了什么。

Answer 1

构建日志没有报告明确的错误，而是表明实际上没有构建任何东西:

S2I source build with plain binaries detected
Copying binaries from /tmp/src to /deployments ...
... done

作为your repo “隐藏”父文件夹中的应用程序源，请尝试指定 contextDir (即 / ，默认情况下)到 springboot-demo为您的构建，或将应用程序源移动到您的 git 存储库的根目录。

您可以使用 oc 编辑构建配置CLI oc edit bc/<build_config_name>或者在从目录部署应用程序期间提供 git 存储库 URL 时，通过单击 “高级选项” 链接或使用 操作 -> 编辑浏览现有构建配置时的菜单项。
