Maven <executions> 和 npm build

Question

我有一个hybrid application：Spring Boot and ReactJS. 在 running/building/generating WAR 时，我已将 pom.xml 设置为将 npm run build 生成的文件从 dist 文件夹复制到 template(spring) 文件夹。 但是在运行mvn clean install 时，会在npm run build 命令之前复制文件，然后生成npm run build 和WAR。这就是前端文件过时的原因。

我的pom.xml 示例是：

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <executions>
                    <execution>
                        <id>prepare-package</id>
                        <phase>prepare-package</phase>
                        <goals>

                </executions>
            </plugin>
        </plugins>
    </build>

如何配置以便在npm run build 之后复制文件？

Answer 1

对于类似的任务，使用 gradle 而不是 maven 是有意义的。任务更加灵活。 例如：

task buildFE(type: Exec) {
     workingDir '../../FrontEnd'
     commandLine 'buildFE.bat'
}

task CopyJava {
  copy{
    from '../OpenJDK'
    into '../../Release/OpenJDK'
  }
}
