Netbeans 无法在 MAVEN Web 应用程序上运行 package.json

问题描述

使用 Netbeans 8.2，我创建了一个新的 MAVEN Web 应用程序.我在 Web Pages 文件夹中放置了一个有效的 package.json 文件，所以它的路径是

C:\Users\xxx\Documents\NetBeansProjects\MyApp\src\main\webapp\package.json

我左键单击 package.json 文件，然后单击 npm install 选项.然后我收到了这些错误/警告

"C:\Program Files\nodejs\npm.cmd" "安装"npm WARN ENOENT ENOENT:没有这样的文件或目录，打开C:\Users\Nick\Documents\NetBeansProjects\MyApp\package.json"npm WARN EPACKAGEJSON C:\Users\xxx\Documents\NetBeansProjects\MyApp 没有描述npm WARN EPACKAGEJSON C:\Users\xxx\Documents\NetBeansProjects\MyApp 没有存储库字段.npm WARN EPACKAGEJSON C:\Users\xxx\Documents\NetBeansProjects\MyApp 没有 README 数据npm WARN EPACKAGEJSON C:\Users\xxx\Documents\NetBeansProjects\MyApp 没有许可证字段.完毕.

我注意到 Netbeans 试图在错误的位置寻找 package.json

C:\Users\Nick\Documents\NetBeansProjects\MyApp\package.json'

而且我似乎不知道如何告诉 IDE 去哪里寻找它.

当我去

项目属性 > JavaScript 库 > npm

我用

得到一个空视图

找不到package.json

我的问题是，如何设置 netbeans 以查看package.json"并运行它?当我尝试在 HTML5 项目中使用它时，它运行良好，但我需要对 Java Web 应用程序项目的 npm 支持.

解决方案

我回答我自己的问题真的很晚，但我最终找到了内置 IDE 机制之外的解决方案.我使用

然后插件将运行并安装一个 package.json 和一个节点运行时在一个单独的目录中，该目录不会与您的项目捆绑在一起，您可以在那里编辑它并重新运行目标.

Using Netbeans 8.2, I've created a new MAVEN web application. I have placed a working package.json file inside the Web Pages folder so it's path is

I left click on the package.jsonfile and click the npm install option. I was then greeted by these errors/warnings

"C:\Program Files\nodejs\npm.cmd" "install"
npm WARN ENOENT ENOENT: no such file or directory, open 'C:\Users\Nick\Documents\NetBeansProjects\MyApp\package.json'
npm WARN EPACKAGEJSON C:\Users\xxx\Documents\NetBeansProjects\MyApp No description

npm WARN EPACKAGEJSON C:\Users\xxx\Documents\NetBeansProjects\MyApp No README data
npm WARN EPACKAGEJSON C:\Users\xxx\Documents\NetBeansProjects\MyApp No license field.
Done.

I noticed Netbeans attempted to look for the package.json at the wrong place

And I can't seem to figure out how to tell the IDE where to look for it.

When I go to

I get an empty view with

My question is, how can I setup netbeans to see that 'package.json' and run it? It worked fine when I tried using it in a HTML5 project, but I need npm support for a Java web app project.

解决方案

I'ts really late to answer my own question but I eventually found a solution outside the the builtin IDE mechanics. I used the frontend-maven-plugin to setup a local npm repo for my project.Than instead of using the npm install option given by the IDE, I used maven to define a goal, and run it using nbactions.xml.

1. To install the plugin, edit your pom.xml (snippet from here), add the plugin descriptor and the execution that will download and install npm inside your repo

   <plugins>
       <plugin>
           <groupId>com.github.eirslett</groupId>
           <artifactId>frontend-maven-plugin</artifactId>
           <version>1.8.0</version>
           <executions>
               <!-- Installs node + npm in your repo -->
               <execution>
                   <id>install node and npm</id>
                   <goals>
                       <goal>install-node-and-npm</goal>
                   </goals>
                   <phase>generate-resources</phase>
               </execution>
               ...
   

2. I've appended this code to the one above, it's an execution that runs npm install(snippet found here)

       ....
       <execution>
           <id>npm install</id>
           <goals>
               <goal>npm</goal>
           </goals>
   
           <!-- optional: default phase is "generate-resources" -->
           <phase>generate-resources</phase>
   
           <configuration>
               <!-- optional: The default argument is actually
               "install", so unless you need to run some other npm command,
               you can remove this whole <configuration> section.
               -->
               <arguments>install</arguments>
           </configuration>
       </execution>
   </plugin>
   

3. Create a package.json file (in the same directory where your pom is) and start putting stuff into it (example)

4. I've added a reference to the npm install goal inside nbactions.xml, I've gave it a display name of npm-install

   </actions>
       ...
       <action>
           <actionName>CUSTOM-npm-install</actionName>
           <displayName>npm-install</displayName>
           <goals>
               <goal>npm</goal>
           </goals>
       </action>
   </actions>
   

5. Then, right click on the Project (from the projects view) -> Run Maven -> npm-install

The plugin will then run and install a package.json and a node runtime in a seperate directory that won't be bundled with your project, you can edit it there and re-run the goal.
