Fehlermeldung beim Kompilieren?

Hallo zusammen,

kann mir jemand sagen, was dieser Fehler bedeutet?

------ Build started: Project: Stromsensor, Configuration: Debug AVR 
------
    Build started.
    Project "Stromsensor.cproj" (default targets):
    Target "PreBuildEvent" skipped, due to false condition; 
('$(PreBuildEvent)'!='') was evaluated as (''!='').
    Target "CoreBuild" in file "C:\Program Files (x86)\Atmel\Atmel 
Studio 6.0\Vs\Compiler.targets" from project 
"C:\Users\Dejan\Desktop\Software_Test_Home\BMS_ATMega328P_Soft\Stromsens 
or.cproj"  (target "Build" depends on it):
      Task "RunCompilerTask"
========== Build: 0 succeeded or up-to-date, 1 failed, 0 skipped 
==========

Nutze das Atmel Studio 6.

Danke im Voraus.
