如何配置Docker以使用Maven构建和运行jar文件？

如何解决如何配置Docker以使用Maven构建和运行jar文件？

说明：

您好，所以我在这个问题上停留了一天多。我的目标是创建一个使maven生成jar文件的dockerfile。我想这样做的原因是允许使用CI / CD。我想创建一个工作流，该工作流允许我的主github分支创建docker映像，然后将其推送到Docker Hub。

以前，我有一个标准文件，可以通过添加构建的jar文件并运行它来创建映像。问题是我的github存储库没有目标文件夹，据我所知它也不应该拥有它。由于此设置，我必须构建映像并将其手动推送到docker hub。这是我要变成工作流程的东西。

我一直在使用什么：

FROM adoptopenjdk/openjdk11:alpine-jre
WORKDIR /app
COPY ../target/ur-codebin-1.0-SNAPSHOT.jar app.jar
EXPOSE 8080
CMD java -jar -Dspring.profiles.active=prod /app/app.jar

---

错误/问题：

我现在面临的这个问题是如何让Maven正确构建项目。每当我尝试构建以下更新的dockerfile时，都会出现一个错误，指示尚未安装节点。令我感到困惑的是，据我所知，vaadin依赖项是在构建项目时安装节点的。所以我为什么会收到这个错误没有道理。

更新的Dockerfile

FROM maven:3.5.2-jdk-8-alpine
WORKDIR /app
COPY pom.xml .
COPY src ./src/
COPY frontend ./frontend/
RUN mvn clean install -Pproduction  #I get the error at this step

CMD java -jar -Dspring.profiles.active=prod ./target/ur-codebin-1.0-SNAPSHOT.jar

令我感到困惑的是，如果我进入堆栈跟踪，就会看到以下堆栈跟踪，其中清楚地指出/root/.vaadin/node/node上的“节点安装成功”

有人对我如何解决此问题有任何想法吗？ 注意：如果您需要更多的堆栈跟踪，我很乐意发送带有完整跟踪的某种文件。
