How do I solve this error? I tried:
Refreshing the project, and rebuilding.
Cleaning the project, and rebuilding.
Closing and reopening the project, and rebuilding
Deleting the project (but not deleting the files — that's a checkbox on the project deletion confirmation dialog), and re- importing it as an existing project, and cleaning and rebuilding.
Deleting the project, deleting the
.project
and.classpath
files in the project, and creating a new project using my files as existing sources.
None of these worked. How do I solve this problem?
