在战争中打包javascript应用（使用grunt和browserify）

Question

I have a project that consists of a javascript client app and a maven+spring based REST web service.

The javascript app is built using browserify and grunt. For this reason I am unable to simply place the html/js source in the src/main/webapp directory of my maven based web service project. What really needs to end up in there is the contents of the javascript app's dist directory after browserify/grunt compilation.

Question is: how can I set things up so that the javascript app is packaged w/ the web service war (note that this will need to include the grunt/browserify build steps)?

Answer 1

This is possible by using the frontend-maven-plugin for maven. I use it do these steps during every maven build:

• Downloading and installing Node.js (if it doesnt exist already)
• Update npm packages
• Executing my frontend build (gulp)
• Gulp will compile my SASS and JS to folders specified in plugin

I can also trigger gulp build by changing files. Part of my POM (should work similar for grunt):

        <plugin>
            <groupId>com.github.eirslett</groupId>
            <artifactId>frontend-maven-plugin</artifactId>
            <version>0.0.26</version>

                <workingDirectory>src/main/frontend</workingDirectory>
                <installDirectory>.</installDirectory>
            </configuration>
            <executions>
                <!-- Config from: https://github.com/eirslett/frontend-maven-plugin -->
                <!-- phase optional for all executions: default phase is "generate-resources" -->
                <!--  disable some of the following executions to improve build speed -->
                <execution>
