When CruiseControl attempts to determine the modification set using Subversion, it may quietly fail. 'Quietly' in the sense that the build will be reported as a success. However, if you check the CruiseControl log, a nasty Subversion exception will be reported even though the build did not fail:
2007-09-14 23:40:28,319 [Thread-5128] ERROR SVN - Error executing svn log command svn log --non-interactive --xml -v -r {2007-09-14T21:32:04Z}:{2007-09-15T05:40:28Z} --username autobuild svn://mm:3691/trunk
org.jdom.input.JDOMParseException: Error on line 3: XML document structures must start and end within the same entity.
at org.jdom.input.SAXBuilder.build(SAXBuilder.java:468)
...The CC log does not show the actual error from Subversion. The problem appears to be that SVN issues an error or warning message prior to or in lieu of its XML output. CC, however, seems to parse out partial results and returns a bogus count of modifications. As a result, the build will continue using source code whose exact revision level is undetermined.
