Guillaume Boué commented on MANTRUN-206:
----------------------------------------
I don't think this can be solved at the plugin level. Once the plugin sees the
POM, the basedir is already replaced with its absolute value in the plugin
configuration, and it would need to make the distinction between a real
pattern, and something that should be escaped. This is not always possible (is
{{\target}} the literal string or a tabulation character followed by arget?).
A possible solution is to escape the pattern manually:
{code:xml}
<configuration>
<target>
<loadresource property="baseDirEscaped">
<propertyresource name="basedir"/>
<filterchain>
<tokenfilter>
<replacestring from="\" to="\\"/>
</tokenfilter>
</filterchain>
</loadresource>
<condition property="dir"
value="${project.reporting.outputDirectory}/xsddoc">
<matches string="${project.reporting.outputDirectory}"
pattern="^${baseDirEscaped}" />
</condition>
</target>
</configuration>
{code}
> Plugin fails with conditional property containing a Windows path.
