angular-cli + mvn：无法启动构建

Question

我使用angular-cli生成了我的angular 2项目。 由于项目和客户的限制，我无法升级到角度4。

我尝试使用frontend-maven-plugin来编译我的角度应用与maven，但是当我启动mvn干净安装时，构建脚本失败。

我得到了错误：

我POM：

Answer 1

您使用的是旧版本的NodeJS和防范机制，你只需要切换到你在maven之外使用的版本。

在终端

运行以下命令：在我的电脑上

npm --version 
node --version 

，这些命令输出v6.11.2为的NodeJS和3.10.10为NPM所以pom.xml应该是这样的：

<nodeVersion>v6.11.2</nodeVersion> 
<npmVersion>3.10.10</npmVersion> 

Answer 2

其实你并不需要一个特定的前端插件任务。

如果在你的环境中你能够运行NPM运行构建比你可以使用exec-Maven的插件，像这样的东西：

<build> 
    <plugins> 
     <plugin> 
     <groupId>org.codehaus.mojo</groupId> 
     <artifactId>exec-maven-plugin</artifactId> 
     <executions> 
      <execution> 
      <id>install npm dependencies</id> 
      <phase>initialize</phase> 
      <goals> 
       <goal>exec</goal> 
      </goals> 
      <configuration> 
       <workingDirectory>${project.basedir}</workingDirectory> 
       <executable>npm</executable> 
       <commandlineArgs>install</commandlineArgs> 
      </configuration> 
      </execution> 
      <execution> 
      <id>build webapp</id> 
      <phase>compile</phase> 
      <goals> 
       <goal>exec</goal> 
      </goals> 
      <configuration> 
       <workingDirectory>${project.basedir}</workingDirectory> 
       <executable>npm</executable> 
       <commandlineArgs>run build</commandlineArgs> 
      </configuration> 
      </execution> 
     </executions> 
     </plugin> 
    </plugins> 
    </build>
