Since yesterday, Eclipse is not updating the .class files of my project. For example the filename.java is up to date, but the filename.class file has a modified date of yesterday. It used to work just fine. Why is this happening?

Few things I would do or double check:

  1. Project > Clean on the project you're working on.
  2. Project > Build Automatically - turned on so the code rebuilds in your workspace on saved changes.
  3. Window > Preferences and make sure your Installed JRE's and Compilers are matching Java versions

I would suggest doing the following

  1. Make sure Java builder is active in the Project -> Properties -> Builders menu
  2. Clean the project and re-build it.
  3. If that doesn't work, remove the .class files manually via File Explorer and give it another try.
