I have a standard web project which no longer builds automatically. At first I realized it wasn’t recognizing my changes… e.g.modifying a simple System.out.println did not change the output of the program. The code changes were not being compiled.

Then I tried running Project > Clean which removed the existing class files and displayed “building workspace” for about 30-45 seconds and completes without any error message. However no class files are created.

What is wrong? I have other My Eclipse projects in my workspace which build O.K.

thanks in advance for any assistance,

James.

Try cleaning your workspace using the -clean command:-

Also, make sure you are updating and checking the same files within the project.

Thanks. I just added the -clean and restarted eclipse. However the problem still remains. When I try to rebuild no class files are created. I forget to mention last time I have eclipse 3.1 and MyEclipse 4.0.

I have created an ant build file as a temporary fix. This does successfully compile the source so I know the files are good. However I would much rather have MyEclpse compile the source automatically so I can take advantage of the hot-sync etc.

What else can I try?

Hello?

I would like you to try a few things:-
1. Make sure the project is Refreshed.
2. Check the end of the log file for any build exceptions. The log file can be found at <workspace>/.metadata/.log
3. Do you have any build errors for your project, like invalid JARs? If you go to the library tab under Java Build Path, are there any error or warning markers on any of the libraries?
