We have a build system based on ant and use parallel subproject directories.
We use Hudson 1.146 and cobertura-plugin 0.8.2. This Hudson version starts the
build from the first module checked out from CVS.
We get
No coverage results were found using the pattern
'../*/target/reports/cobertura/xml/coverage.xml'. Did you generate the XML
report(s) for Cobertura?

The coverage file is located at
<subproject>/target/reports/cobertura/xml/coverage.xml

I could not think of any pattern for the cobertura plugin that would catch these
coverage files, since the search starts at the umbrella project that is located
parallel to the actual software projects.

Is this an incompatibility caused by a change in hudson itself?

Martin.
