如何将 Spring Boot 和 Angular 应用程序部署为单个 war 文件？

Question

我想将 Spring Boot 和 Angular 应用程序部署为单个 war 文件。我尝试过如下操作，

在 Angular 应用程序中创建了一个 build.gradle 文件

plugins {
  id 'java'
  id "com.moowork.node" version "1.3.1"
}

// 2
node {
  version = '10.15.3'
  npmVersion = '6.9.0'
  download = true
}

// 3
jar.dependsOn 'npm_run_build'

// 4
jar {
  from 'dist/projectName' into 'static'
}

在spring boot项目的build.gradle文件中添加如下内容，

implementation(project(':angularProject')

在 Spring Boot 项目的 settings.gradle 文件中添加以下内容，

include ':angularProject'
project(':angularProject').projectDir = new File('../angularProject')

当我构建 spring boot 项目时，我可以在 spring boot 项目位置看到 angularProject，但我希望它自动显示在 spring boot 项目的资源文件夹中的 static 文件夹中。我错过了什么吗？非常感谢任何帮助。

编辑：

现在，在构建项目时出现以下错误

Could not determine the dependencies of task ':war'.
> Could not resolve all task dependencies for configuration ':runtimeClasspath'.
   > Could not resolve project :frontendProject.
     Required by:
         project :
      > No matching variant of project :frontendProject.was found. The consumer was configured to find a runtime of a library compatible with Java 8, packaged as a jar, and its dependencies declared externally but:
          - Variant 'apiElements' capability backendProjectName:frontendProject:unspecified declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component compatible with Java 15 and the consumer needed a runtime of a component compatible with Java 8
          - Variant 'runtimeElements' capability backendProjectName:frontendProject:unspecified declares a runtime of a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component compatible with Java 15 and the consumer needed a component compatible with Java 8

谢谢。

使用Maven插件frontend-maven-plugin https://github.com/eirslett/frontend-maven-plugin 。见https://marco.dev/deploy-java-angular-one

如果您使用 Gralde，请使用此插件 https://github.com/siouan/frontend-gradle-plugin 。但是frontend-maven-plugin更稳定。

在 frontend-maven-plugin 上，我们正在构建 angular，在 maven-war-plugin 上，我们将 angular 构建文件包含到 war 文件中或排除一些文件
