I wrote an application in the Eclipse, which was successfully compiled and run. After that, in a corresponding directory I found *.java and *.class files. Then I have deleted the *.class file and now I do not know how can I get it back.
Eclipse writes me "A class file was not written. The project may be inconsistent, if so try refreshing this project and building it".
By the right click on the project I got a drop down menu in which I found "Refresh" but I cannot find out how can I "build" the project.
So, how can I generate the class file again?
Thank you in advance for any help.
- Cleaning the project should be enough to start the build. Menu:Project ->Clean
- Check that automatic build is enabled. Project -> Build Automatically
- If automatic build is disabled use build all. Menu: Project -> Build All
I get this error message when I have an inner class, and the total name of the main class and its inner classes exceeds 128 characters. This happens both on OpenJDK and Sun JDK 6. The solution for me was to shorten the inner class names.
