Overview

The Apache Sling HTL Maven Plugin provides support for validating HTML Template Language scripts from projects during build time, reporting issues like:

  • syntax errors;
  • expression warnings (e.g. missing required display contexts, sensible attributes with dynamic values, etc.);
  • incorrect usage of block elements.

It is compatible with m2eclipse and supports executing its goals during Eclipse incremental builds.

The HTL Maven Plugin has only one goal:

  • htl:validate is bound to the generate-sources phase and is used to validate/transpile HTL scripts.

Usage
