I'm working on standalone headless RCP. It works without problem when I execute the application and product in eclipse IDE, but when I export and execute it, I got this error in the log file.

Referring from this post, I understand that I've got a newer version of a plug-in without its dependencies, and there is something wrong in the runtime path. However, I'm not sure exactly what might cause this error.
What might be wrong? Why I have this error only when I execute it as standalone?
I have build.properties file
output.. = bin/
bin.includes = META-INF/,\
plugin.xml,\
.
source.. = src/

I have only one item: "." in Bundle-ClassPath.
There is also the possibility to add the missing bundle via extra dependency configuration, directly to the failing bundle:
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho.version}</version>
<configuration>
<dependency-resolution>
<extraRequirements>
<requirement>
<type>eclipse-plugin</type>
<id>org.eclipse.jface.text</id>
<versionRange>0.0.0</versionRange>
</requirement>
</extraRequirements>
</dependency-resolution>
</configuration>
</plugin>
