maven-frontend-plugin構建錯誤

Question

我一直在研究在eclipse中獲取角度2設置。設置maven時遇到錯誤。我對maven相對來說比較陌生，我不確定如何克服這個錯誤。任何幫助，將不勝感激。

兩件事情我可以看到馬上，可能是問題，但我不知道如何解決，或者爲什麼它造成的錯誤：npm ERR! missing script: build &

[INFO] +-- UNMET PEER DEPENDENCY rxjs@5.0.0-beta.6 
[INFO] `-- UNMET PEER DEPENDENCY zone.js@^0.6.12 

的package.json文件

{ 
    "name": "budget_calculator", 
    "version": "1.0.0", 
    "dependencies": { 
    "angular2": "2.0.0-beta.17", 
    "es6-shim":"^0.35.0", 
    "reflect-metadata":"0.1.2", 
    "rxjs":"5.0.0-beta.6", 
    "zone.js":"^0.6.12" 
    } 
} 

我用來安裝插件的pom.xml部分

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-compiler-plugin</artifactId>

        <!-- Optional configuration which provides for running any npm command -->

Answer 1

看來你缺少這些依賴於package.json

"dependencies": { 
    ... 
    "es6-shim":"^0.35.0", 
    "reflect-metadata":"0.1.2", 
    "rxjs":"5.0.0-beta.6", 
    "zone.js":"^0.6.12" 
} 

您還缺少一個劇本叫build，您可以在package.json添加它，因爲在你pom.xml，你有<id>npm run build</id>

{ 
    ... 
    "scripts": { 
    "build": "..." 
    }, 
    "dependencies": { 
    ... 
    } 
}
