How to stop backslashes being escaped when filtering with maven-resources-plugin?

Question

I'd like to use the Maven Resources Plugin to set the XML schema location within an XML resource file:

<root xsi:noNamespaceSchemaLocation="${env.myxsdpath}" ...>

This works except for one thing - the substituted path has double backslashes instead of a single blackslash, e.g:

<root xsi:noNamespaceSchemaLocation="C:\\mypath\\myschema.xsd" ...>

So two questions:

1. Is this a valid format for specifying the XSD file?
2. Is there a way to tell Maven to use a single backslash instead of double backslashes?

The environment variable myxsdpath is C:\mypath\myschema.xsd. The maven-resources-plugin doesn't have any special configuration other than specifying the files that are to be included with filtering turned on.

Answer 1

This behaviour is controlled by the escapeWindowsPaths attribute of the maven-resources-plugin, introduced in version 2.4. It defaults to true meaning that, by default, all back-slashes will be escaped, turning single \ into double \\.

Whether to escape backslashes and colons in windows-style paths.

Sample configuration to disable this:

<plugin>
  <artifactId>maven-resources-plugin</artifactId>
  <version>2.7</version>
  <configuration>
    <escapeWindowsPaths>false</escapeWindowsPaths>
  </configuration>
</plugin>
