I am using Maven to build an HTML webapp. I have one profile for debug and another profile for release. In the debug profile I’d like to have un-compressed Javascript used in the HTML page but in the release profile I concatenate all of the Javascript files and then compress them using Googles Closure compiler.

So basically I have 2 lists of Javascript files that I need to write out as <script> tags into the HTML page based on which profile is selected.

Is there a Maven plugin that I could configure with different lists for different profiles that could generate the HTML file as necessary?

    After much investigation I determined the best options was to write my own maven plugin. I have a simple .html template which contains directives on where to insert CSS and JS tags into the HTML:

    <!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Fifa Social - Hello World</title>
  <meta name="description" content="Hello World app for Fifa Social">

  <meta name="viewport" content="width=device-width">

  $cssIncludes$
  $jsIncludes$

</head>
<body>
    <p>Page content</p>
</body>
</html>

    I then have a Maven plugin that runs in the “generate-sources” phase of the Maven lifecycle which takes the template and replaces the $cssIncludes$ and $jsIncludes$ with the appropriate list of <script> and <link> tags. (Note: I am using the antlr stringtemplate Java library as a dependency for my plugin).

    I can’t post the actual plugin since it is a proprietary project but it is a single Java class that extends from AbstractMojo

    • it has @parameter properties to read the <configuratioon> from the POM
      • location of html template
      • location of output file
      • the list of JS files
      • the list of CSS files
    • during execute it
      • reads the html template from a file and stores is as a string
      • creates an org.antlr.stringtemplate.StringTemplate from the html template
      • using the default org.antlr.stringtemplate.language.DefaultTemplateLexer.
      • loops through the JS and CS files from the configuration creating the <script> and <link> tags as strings
      • uses template.setAttribute to bind the built string to $cssIncludes$ and $jsIncludes$
      • writes the template to the files system

    It works quite nicely. I simply send a different list of JS and CSS files to the plugin based on the current Maven profile.
