Grunt integration with Maven

Question

I am getting below error while integrating Grunt with Maven. I have gone through similar questions on stackoverflow and it didn't help me hence I am asking it again. I have a Gruntfile.js and package.json file both at the root level of project. I have also added relevant entries in pom.xml for installing npm , node and grunt. When I run the maven build , it does create 2 folders Node and Node_modules and I can see that grunt_cli and other modules are installed but still I am getting below error.

I am new to Grunt and Node. Please guide, what am I missing here?

Errors:- Error 1 ->Local Npm module "grunt-cli" not found. Is it installed?

Error 2 ->Failed to execute goal com.github.eirslett:frontend-maven-plugin:0.0.16:grunt (grunt build ) on project my_project: Failed to run task: 'grunt --no-color' failed. (error code 3)

Answer 1

Try to remove the following snippet from your pom.xml

<execution>
    <id> npm run build </id>
    <goals>
     <goal>npm </goal>
    </goals>
    <configuration>
     <arguments> run build </arguments>
    </configuration>
 </execution>

Default argument of grunt goal is build. If you put the argument --no-color you should also add the build argument.
