My RCP plugin refuse to load

Question

i'm making a little Eclipse plugin. When i launch it inside the eclipse RCP, all works fine. But when i export it as feature and install it on a standard Eclipse i get this error :

Plug-in foo.bar was unable to load class foo.bar.Editor.

I have searched into the generated feature and plugin jar and the Editor.class is inside bin/foo/bar/Editor.class.

So what is the problem?

This is my plugin build.properties :

bin.includes = META-INF/,\
               plugin.xml,\
               icons/,\
               bin/info/
jars.compile.order = cucumber-core-1.2.4.jar,\
                     cucumber-html-0.2.3.jar,\
                     cucumber-java-1.2.4.jar,\
                     cucumber-junit-1.2.4.jar,\
                     cucumber-jvm-deps-1.0.5.jar,\
                     gherkin-2.12.2.jar
src.includes = src/,\
               icons/,\
               plugin.xml,\
               META-INF/,\
               .project,\
               .classpath,\
               .settings/,\
               build.properties

This is my MANIFEST.MF

Assuming your source code is in the src folder and the output classes are in the bin folder the build.properties should contain something like:

source.. = src/
output.. = bin/
bin.includes = META-INF/,\
               .,\
               icons/,\
               plugin.xml

(plus your jar.compile.order)

If you want those jars to be included in the plugin they need to be listed in the 'bin.includes' as well.
