Error when compiling in Netbeans.

[greendog99]

I am getting the following error every time I try to compile our program in Netbeans.
Note: C:/Users/Student/Documents/NetBeansTestPRogram1/src/edu/wpi/first/wpilibj/defaultCode/DefaultRobot.java uses or overrides a depracated API.
Not:Recompile with -Xlint:deprecation for details.
The computer we are using to compile isn't the first one that wrote to the cRIO since the Netbeans firmware was flashed.
