[package] $ cmd.exe /C '"C:\hudson\tools\Ant_1.8.1\apache-ant-1.8.1\bin\ant.bat "-DCONFIG_BUILD_SELECTOR=^{<StatusBuildSelector}>
^<stable>true^</stable^>
^{</StatusBuildSelector}>" "-DPLATFORM_BUILD_SELECTOR=^{<StatusBuildSelector}>

^{</StatusBuildSelector}>" "-DIDE_BUILD_SELECTOR=^{<StatusBuildSelector}>

^{</StatusBuildSelector}>" clean && exit %%ERRORLEVEL%%"'
The syntax of the command is incorrect.

I believe you need to use the caret (^) to escape the newlines as well in the cmd.exe command line. (Hence, and ant/hudson core component fix?)

Alternative fix, the BUILD_SELECTOR values could remove newlines from the XML (I assume they are just for prettiness).
