Eclipse RCP - cant resolve importing libraries in final build - eclipse

Question

I try to build/export Eclipse RCP product. I have several JAR libraries (not external JARs but they are inside project root folder). I am able to launch application/product in Eclipse environment but i cannot export it as Plug-in Development/Eclipse product. There is no error during exporting but when i try to run my application .exe file the error occurs:
"An error has occurred. See the log file:
C://...configuration/123123.log"
Inside log there is:

EDIT: ok i see that when i export project to .exe, logs.zip file is created. Inside this log there are tons of errors.
Those errors looks like missing JAR: The import XXX cannot be resolved XXX - package that is inside JAR library
1. ERROR in
C:\Users\X\workspaceRPC\SmoothFlow\src\app\amazonCalls\BaseAmazonCall.java (at line 3)
import com.amazonservices.mws.orders._2013_09_01.MarketplaceWebServiceOrdersAsyncClient;
^^^^^^^^^^^^^^^^^^
The import com.amazonservices cannot be resolved
EDIT: Greg thank you for Your help, i have added in build.properties all the JARs but the problem still exists (the same errors). My build.properties looks like:
source.. = src/
output.. = bin/
bin.includes = plugin.xml,\
META-INF/,\
.,\
lib/,\
lib/FastInfoset.jar,\
lib/MWSClientJavaRuntime-1.0.jar,\
lib/MWSOrders_2013-09-01_v2015-09-24.jar,\
...
jars.compile.order = .,\

As well as listing the Jars in the MANIFEST.MF (shown on the Runtime tab in the editor) you must also list the jars in the 'build.properties' file. This is shown on the 'Build' tab of the MANIFEST.MF/plugin.xml/build.properties editor.
An example:
In this example I have three jars in a 'lib' directory included in the build.
The build.properties file itself will look like:
source.. = src/
output.. = bin/
bin.includes = META-INF/,\
.,\
plugin.properties,\
plugin.xml,\
about.html,\
about_files/,\
lib/,\
lib/jogg-0.0.7.jar,\
lib/jorbis-0.0.15.jar,\
lib/vorbisspi1.0.2.jar,\
icons/
Everything you want included in the plugin must be listed in the build.properties.
