【问题描述】：

我正在尝试在 Heroku 上部署一个 Spring Boot 应用程序。这是我的 heroku 错误日志：

remote:        [ERROR] COMPILATION ERROR :

remote:        [ERROR] /tmp/build_ffefd73b56c7017473a0b98cce9d815d/src/test/java/com/ticketbooking/ticketbooking/TicketbookingApplicationTests.java:[3,29] package org.junit.jupiter.api does not exist

remote:        [INFO] -------------------------------------------------------------
remote:        [INFO] ------------------------------------------------------------------------

我很困惑，因为我没有任何测试类，我不知道它从哪里获得 TicketbookingApplicationTests 类。

这是我的 pom.xml：

标签： spring-boot heroku maven-compiler-plugin

【解决方案1】：

如果您没有找到这些类，请尝试构建跳过测试步骤：

mvn install -DskipTests

【讨论】：

我认为 heroku 在您尝试部署时使用 --DskipTests 选项：“git push heroku master”，它运行“./mvnw -DskipTests clean dependency:list install”

【解决方案2】：

我解决了这个问题： How can I reconcile detached HEAD with master/origin?

我的 git 处于与 origin/master 分离的 HEAD 状态，其中包含一些 junit 测试。

【讨论】：

【解决方案3】：

Heroku 必须知道您的项目中使用的是哪个 JDK 版本（我的系统的 JDK 版本是 11）。将以下行添加到 system.properties 文件。如果该文件不存在，则在项目根目录下创建它。用你的替换 11。

java.runtime.version=11
