Maven: XSLT transformation of pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
...

This won't work:

<xsl:template match="/project/version">...

pom.xml is namespaced, so your XSLT stylesheet needs some tweak.

You need to declare a namespace, effectively assigning it a prefix.

<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:pom="http://maven.apache.org/POM/4.0.0"
>
    <xsl:template match="/pom:project/pom:version">
        <xsl:value-of select="string()"/>
    </xsl:template>

Here you define the prefix for the POM's default namespace. The same applies for other namespaces, if others are ever used.
