Problema con el PATH de Netbeans

[cesmichael]

Bueno es la primer a vez que descargo lsoplugins para Netbeans. Descargue los plugins para el scala. Instale los Jar's y todo bien el problema es que a la hora de compilar los proyectos me sale el siguiente error adems de un mensaje de nullpointer esception. al aprecer he ehcho algo mal

Compiling 1 source file to C:\Documents and Settings\Administrador\Mis documentos\NetBeansProjects\ScalaApplication11\bui ld\classes
C:\Documents and Settings\Administrador\Mis documentos\NetBeansProjects\ScalaApplication11\nbp roject\build-impl.xml:405: The following error occurred while executing this line:
