[HELP] No robot Code

Here is a screenshot of our netbeans. The code doesn’t work anymore and the file keeps saying needs to be compiled. The error is exactly like this one:
“Need to Compile” badges
The Need to Compile icon badge (a little wrench next to the node in Projects) is shown whenever the class file is not up to date, such as when the source file was changed after the last compilation. If the build directory is populated by classes produced by the internal compiler (e.g. after Run is selected) this cannot happen: compilation is always performed after the file is saved. If the build directory contains classes generated by Ant (e.g. after Clean and Build) the sources need to be compiled explicitly to get rid of this badge. The cause is described earlier: the class files in the build directory are not updated upon save in this case.

Can anyone tell us how to fix the problem so we can get the robot back and running?
