Java Forum / General / April 2006why filed updates by elipse cannot be detected by ant
After I update some files in eclipse, then if I execute ant to do a compile, the ant does not compile the updated files. Why? But if I use other editor, say ultraedit or eaven Dos's editor to eidt the file, ant can find the files are updated and compile these files. This is really annoying? What happened here, can anyone give me a direction? Thanks, David > After I update some files in eclipse, then if I execute ant to do a > compile, the ant does not compile the updated files. Why?

Ant build scripts? Something else? - Oliver david wolf schrieb: > After I update some files in eclipse, then if I execute ant to do a > compile, the ant does not compile the updated files. Why? Because eclipse by default compiles java source files imediately after saving. Therefore the class files are up to date if you run ant afterwords. So ant has nothing to compile. > But if I use other editor, say ultraedit or eaven Dos's editor to eidt > the file, ant can find the files are updated and compile these files. > This is really annoying? No, thats the opposite. A stupid text editor doesn't know how to compile your classes and only stores the modified java source files. If you run ant afterwords, it detects that the java sources are newer than the class files and compiles them. Just like good old make. Kind regards, Frank  SignatureGeld allein macht nicht glücklich. Es kommt auch auf die Menge an... Frank said is right. Thank you so much ! Another problem. The files I modified are java source files. If I made any modification, say errors, to the java source file. Why the time stamp of the class file also updated? > Frank said is right. Thank you so much ! > > Another problem.

Eclipse will compile and generate class file for sources which have errors in them. It simply replaces the body of the methods with errors to throw exceptions. - Oliver Free MagazinesGet these publications absolutely FREE for up to 12 months.
