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?
update platform sdk version to rev 21 it can be solved. I updated platform SDK from rev 20 to rev 21, and restart eclipse, it's solved.
