Wouldn't it be nice to combine simplicity and power of stringtemplate (http://www.stringtemplate.org/) with convenience and power of Maven build tool? I think so -- yet could not find such combination. But this small project aims to fix this deficiency.

Usage

Required information for running is to know:

• groupId: com.fasterxml
• artifactId: maven-stringtemplate-plugin

and goal, which is usually 'process'.

Given this, you would add something like this in your Maven pom.xml:

<plugin>
  <groupId>com.fasterxml</groupId>
  <artifactId>maven-stringtemplate-plugin</artifactId>
  <version>{LATEST YOU CAN FIND}</version>
  <configuration>
      <inputDir>src/templates</inputDir>
  </configuration>
</plugin>

Current status

Plug-in works as is. If you want more features, go ahead, fork and when you are done send a pull request.

Configuration

Following properties can be configured (note that these are properties to add in pom.xml, within -- equivalent system properties use "stringtemplate." prefix)

Input settings

• inputDir (no default): Defines input directory (relative to project base directory) -- all files (with suitable suffix) will be processed, recursively
• inputSuffix (defaults to ".st"): Suffix of input files to process; only files that end with the suffix are processed
• encoding (defaults to "UTF-8"): Character encoding of input files; also used for (re)encoding results
• templateDir (defaults to value set for 'inputDir'): Defines directory (relative to project base) that contains templates included by input files (if any). Note that Stringtemplate requires suffix of '.st' for included templates.

Output settings

• outputDir (defaults to '${project.build.directory}'): Directory under which processed template output is stored; retains input structure for sub-directories
• outputSuffix (defaults to ""): Suffix to use for output files, instead of input suffix (i.e. inputSuffix is replaced with outputSuffix)

Template settings

• attributes (no defaults): Map of key/value pairs; attributes that Stringtemplate can use. Added under 'attributes' element in configuration so that key is element name, and value is textual element value
