JarCastingnvu-maven-plugin
maven plugin for HTML validation, using the Nu Html Checker (v.Nu)
The plugin can be configured to be run in the valdiation phase of the maven build and cause the build to fail in case errors are reported.
Usage
Add the plugin to your pom.xml:
<build>
<plugins>
<plugin>
<groupId>nu.validator</groupId>
<artifactId>vnu-maven-plugin</artifactId>
<version>1.0.0</version>
<!-- The plugin should hook into the validate goal -->
<executions>
<execution>
<goals>
<goal>validate</goal>
</goals>
</execution>
</executions>
<configuration>
<filesets>
<fileset>
<directory>...</directory>
...
</fileset>
</filesets>
[<validator>...</validator>]
</configuration>
</plugin>
</plugins>
</build>
The configuration is also made in the pom.xml. There are defaults in place, you only need to configure at least one fileset to point to the files to be validated.
The fileset configuration consists of a directory (relative to the maven project root) and an optional ant glob directive to filter the contents of the directory. Directories are scanned recursively by default. Example:
<fileset>
<directory>src/main/resources/templates</directory>
<glob>**.html</glob>
</fileset>
The validator can also be configured:
<validator>
<warnings>WARN</warnings>
<forceType>HTML</forceType>
<filters>
<filter>
...
</filter>
</filters>
</validator>
Here, all settings are optional.
Handling warnings
By default, warnings are displayed as such and don't cause the build to fail. It can be configured through the directive:
- WARN (default) - show warnings
- IGNORE - supress warnings
- ERROR - treat as errors (affects filtering, see below)
Forcing file type
By default, the file type (html/xhtml, css, svg) is determined by the file extension. Through the directive, it is possible to force all files to be considered on of types HTML, CSS, SVG or XHTML.
Filtering
It is possible to filter warnings and/or errors based on (WARN, ERROR, ALL, optional, default ALL) and a . Filtered items are completely ignored. Mutiple filters can be configured. Example:
<filter>
<regex>Duplicate ID "[a-zA-Z0-9.]*"</regex>
<type>ERROR</type>
</filter>
Additional (general) options
Failfast
Fail on first error (default is to process all errors and fail in the end if there are errors)
<failfast>true</failfast>
ASCII / Unicode quotes
By default, quotes in the errors messages will be displayed as ASCII quotes. It is possible to switch to unicode quites by setting this option to 'false'
<asciiquotes>false</asciiquotes>
