maven使用com.github.eirslett在maven中构建angular项目

我的项目结构如下：

demo-welcome
 +-- pom.xml
 +-- package.json
 +-- src
 |  +-- files
 +-- dist
 |  +-- files

  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

     <artifactId>demo-welcome</artifactId>
     <packaging>war</packaging>
     <version>1.0</version>
     <name>Welcome Page for Demo</name>
     <url>http://maven.apache.org</url>
     <build>
        <finalName>demo-welcome</finalName>
        <pluginManagement>
           <plugins>
              <plugin>
                  <groupId>com.github.eirslett</groupId>
                  <artifactId>frontend-maven-plugin</artifactId>
                  <executions>
                    <execution>
                      <id>ng build</id>
                      <goals>
                          <goal>npm</goal>
                      </goals>
                      <phase>generate-resources</phase>
                      <configuration>
                          <arguments>run build</arguments>
                      </configuration>
                    </execution>
                  </executions>
              </plugin>
              <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-war-plugin</artifactId>
                 <configuration>
                    <webXml>WEB-INF/web.xml</webXml>
                    <webResources>
                       <resource>
                          <directory>dist</directory>
                       </resource>
                    </webResources>
                    <encoding>UTF-8</encoding>
                 </configuration>
                 <executions>
                   <execution>
                     <phase>package</phase>
                   </execution>
                 </executions>
              </plugin>
           </plugins>
        </pluginManagement>
     </build>
  </project>

我想要实现的是，在maven的构建阶段，我得到一个目标，该目标生成我的dist文件夹，其中包含最终结果

所以我读了这个例子：

我的package.json中有

"scripts": {
  "ng": "ng",
  "start": "ng serve",
  "build": "ng build --prod",
  "test": "ng test",
  "lint": "ng lint",
  "e2e": "ng e2e"
},

然后，我的pom.xml如下所示：

demo-welcome
 +-- pom.xml
 +-- package.json
 +-- src
 |  +-- files
 +-- dist
 |  +-- files

  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
     <modelVersion>4.0.0</modelVersion>
     <groupId>com.denv</groupId>
     <artifactId>demo-welcome</artifactId>
     <packaging>war</packaging>
     <version>1.0</version>
     <name>Welcome Page for Demo</name>
     <url>http://maven.apache.org</url>
     <build>
        <finalName>demo-welcome</finalName>
        <pluginManagement>
           <plugins>
              <plugin>
                  <groupId>com.github.eirslett</groupId>
                  <artifactId>frontend-maven-plugin</artifactId>
                  <executions>
                    <execution>
                      <id>ng build</id>
                      <goals>
                          <goal>npm</goal>
                      </goals>
                      <phase>generate-resources</phase>
                      <configuration>
                          <arguments>run build</arguments>
                      </configuration>
                    </execution>
                  </executions>
              </plugin>
              <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-war-plugin</artifactId>
                 <configuration>
                    <webXml>WEB-INF/web.xml</webXml>
                    <webResources>
                       <resource>
                          <directory>dist</directory>
                       </resource>
                    </webResources>
                    <encoding>UTF-8</encoding>
                 </configuration>
                 <executions>
                   <execution>
                     <phase>package</phase>
                   </execution>
                 </executions>
              </plugin>
           </plugins>
        </pluginManagement>
     </build>
  </project>

我还尝试从pom中删除所有插件，只运行前端maven插件，但它似乎没有做任何相关的事情，即使没有失败，也没有做任何事情

我在React项目上也有同样的问题！不过，这只是偶尔发生的，它会通过运行两个连续的Maven构建而消失。我想这与缓存和清理有关
