我的项目结构是这样的：
demo-welcome
+-- pom.xml
+-- package.json
+-- src
| +-- files
+-- dist
| +-- files
我想要实现的是，在maven的构建阶段，我得到一个目标，用最终结果生成我的dist文件夹。
所以我正在读这个例子： build angular 2 project in maven
我的package.json
"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看起来像这样：
<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">

<groupId>com.avaloq.denv</groupId>
<artifactId>demo-welcome</artifactId>
<packaging>war</packaging>
<version>1.0</version>
<name>Welcome Page for Sales</name>

</configuration>
<executions>
<execution>
<phase>package</phase>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
</project>
我的想法是让NPM构建创建我的dist文件夹，然后将其打包
但似乎frontend-maven-plugin从未真正运行过，我不明白为什么。
这是输出

我还尝试从pom中运行删除所有插件并仅运行frontend-maven-plugin，但它似乎与它没有任何关系，即使它没有失败也没有做任何事情。
