带有npm安装的exec-maven-plugin

Question

我尝试在我的项目中使用exec-maven-plugin。

以下是代码

            <plugin>
          <artifactId>exec-maven-plugin</artifactId>
          <groupId>org.codehaus.mojo</groupId>
          <version>1.6.0</version>
          <executions>
            <execution>
              <id>npm install</id>
              <goals>
                <goal>exec</goal>
              </goals>
              <phase>generate-resources</phase>
              <configuration>
                <executable>${node.directory}/${npm.executable}</executable>
                <arguments>
                  <argument>install</argument>
                </arguments>
                <workingDirectory>src/main/angular2/tourism</workingDirectory>
                <target>
                  <echo message="Npm install" />
                </target>
              </configuration>
            </execution>
          </executions>
        </plugin>

下面是我的目录结构

​

上面提到的错误是

/Users/admin/Application-Marwen/workspace/Tourism/Tourism-Web/node/npm: line 34: node: command not found

你能帮帮我吗？

我使用know前端-maven-plugin

以下是代码

        </plugin>
        <plugin>

                </execution>
            </executions>
        </plugin>

和assembly.xml文件

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">
<id>distribution</id>
<formats>
    <format>zip</format>
</formats>

<includeBaseDirectory>false</includeBaseDirectory>

<fileSets>
    <fileSet>
        <outputDirectory>statics</outputDirectory>
        <directory>dist</directory>
        <includes>
            <include>**/*</include>
        </includes>
    </fileSet>
</fileSets>

​

目标是准备一个包含已编译代码的zip文件，以便将其部署到服务器上

下面是获得的目录结构

​

​

1)我不明白为什么dist文件夹没有包含编译后的代码(我还想知道它到底必须包含什么) 2) node和npm安装在tourisml/node目录中，为什么3)有一个错误，说明

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4:single (cfg-main-resources) on project tourism-web: Failed to create assembly: Error creating assembly archive distribution: You must set at least one file. -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4:single (cfg-main-resources) on project tourism-web: Failed to create assembly: Error creating assembly archive distribution: You must set at least one file.

通常我应该得到一个压缩文件(${project.artifactId}-${project.version}.zip)，我想它失败了，因为里面没有文件。对吗？

与使用exec-maven-plugin相比，我建议您查看一下使用npm install构建节点源代码的frontend-maven-plugin。

使用这个插件，你不需要在你的机器上安装npm或node：这个插件自己管理，所以你不会遇到像command not found这样的问题。如下所示的配置应该可以工作：

<plugin>
    <groupId>com.github.eirslett</groupId>
    <artifactId>frontend-maven-plugin</artifactId>
    <version>1.6</version>
    <configuration>
        <workingDirectory>src/main/angular5/tourism</workingDirectory>
        <!-- where to install npm -->
        <installDirectory>${project.build.directory}/install</installDirectory>
    </configuration>
    <executions>
        <execution>
            <id>install-node-and-npm</id>
            <goals>
                <goal>install-node-and-npm</goal>
            </goals>
            <configuration>
                <nodeVersion>v${node.version}</nodeVersion>
                <npmVersion>${npm.version}</npmVersion>
            </configuration>
        </execution>
        <execution>
            <id>npm-install</id>
            <goals>
                <goal>npm</goal>
            </goals>
            <configuration>
                <arguments>install</arguments>
            </configuration>
        </execution>
    </executions>
</plugin>

我已经安装了节点，并将安装的文件夹移动到${project.baseUri}/ node /下。

这个错误现在已经解决了，我可以在命令提示符下使用下面的命令来执行npm安装。

c:\main\prjt\apphost_prjt>mvn frontend:npm

最后，我使用了前端maven-plugin

下面是pom.xml的摘录

        <plugin>
            <groupId>com.github.eirslett</groupId>
            <artifactId>frontend-maven-plugin</artifactId>
            <version>1.6</version>
            <configuration>
                <workingDirectory>src/main/angular5/tourism</workingDirectory>
                <!-- where to install npm -->
                <installDirectory>temp</installDirectory>
            </configuration>                
            <executions>
                <execution>
                    <id>install node and npm</id>
                    <goals>
                        <goal>install-node-and-npm</goal>
                    </goals>
                    <phase>generate-resources</phase>
                    <configuration>
                        <nodeVersion>v8.11.3</nodeVersion>
                        <npmVersion>6.3.0</npmVersion>                      
                    </configuration>                        
                </execution>
                <execution>
                        <id>npm install</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                        <!-- Optional configuration which provides for running any npm command -->
                        <configuration>
                            <arguments>install</arguments> 
                        </configuration>
                 </execution>
                 <execution>
                     <id>prod</id>
                     <goals>
                       <goal>npm</goal>
                     </goals>
                     <configuration>
                       <arguments>run-script build</arguments>
                     </configuration>
                     <phase>generate-resources</phase>
                  </execution>                                                      
            </executions>
        </plugin>
