Description Matthew Webber CLA 2011-01-07 12:33:19 EST 
In an rmap I have the following:
  <rm:propertyElement key="subversion_authentication_string">
    <bc:replace pattern=".*not\.set.*" replacement="">
      <bc:constant value="${svn.username}:${svn.password}@"/>
    </bc:replace>
  </rm:propertyElement>
  <rm:propertyElement key="subversion_url">
    <bc:constant value="https://${subversion_authentication_string}myserver/svn"/>
  </rm:propertyElement>

The idea here is that is svn.username and svn.password are both set (on the command line or in the CQUERY), then ${subversion_authentication_string} will contain the appropriate text, otherwise it will be the empty string.

However, this results in
org.xml.sax.SAXParseException: pattern but no replacement
(I get the same result if I omit the replacement= attribute entirely).

I can work around this, but it seems to me that an empty string should be a valid replacement.
