[FIXED] The class folder is not associated to any output library entry

Issue

My Eclipse plugin project which holds libraries used by other OSGi plugins gives me the following warning:

The class folder 'lib/' is not associated to any output library entry.

What does it mean? Can I safely ignore it?

The whole feature consisting from 20 plugins works well, but I do not like to have any warnings in my code.

My build.properties file is:

source.. = src/
output.. = bin/
bin.includes = META-INF/,\
           bin/,\
           lib/,\
           .

The search on google gave me this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=297483, but I'm still not sure how to fix this warning.

Solution

I found this hint to be helpfull (first google hit, as of 03-SEP-2013) http://dev.eclipse.org/mhonarc/lists/pde-dev/msg01822.html

I removed META-INF from my bundle build path, cleaned (rebuilt) the project and the warning disappeared.
