Swagger Compliance Assertion - Is it possible to use a relative swagger url path?

Is it possible to provide a relative path as the URL for a Swagger Compliance Assertion? I know it is possible when using the Schema Compliance assertion for SOAP requests. I've tried various combinations (for example: using ${projectDir} etc.) but with no luck thus far...

 

Swagger Example:

 

<con:assertion type="SwaggerComplianceAssertion" 
	id="678ae158-9e15-418d-b145-65aa7a32bc5e" 
	name="Swagger Compliance Assertion">
	<con:configuration>
		<swaggerUrl>C:\ABC\API\metrics\metrics-v1\swagger\Test.swagger.json</swaggerUrl>
		<strictMode>true</strictMode>
	</con:configuration>
</con:assertion>

WSDL Example:

<con:assertion type="Schema Compliance" id="710c1657-1fa0-491a-98b9-c8e4d66169c3" name="Schema Compliance">
    <con:configuration>
        <definition>../mds/apps/services/Testing/App/Proxy/Trial_Business_v1.wsdl</definition>
    </con:configuration>
</con:assertion>

If anyone has had any success with this, please let me know.

 

Thanks!
