MissingResourceException: Can't find bundle base name - spring

Question

When running a jar file that i created from a maven project as such:
java -jar basictool.jar
I get this error exception:
Exception in thread "main" java.lang.reflect.InvocationTargetException

I created the jar file by using the maven jar creation wizard:
Right-click on project, select Export > Java > Runnable JAR file with options
Launch configuration: BasicTool - work
Export destination: C:\Users\Victor\Documents\basictool.jar
Library handling: Package required libraries into generated JAR
The version.properties file is kept inside of the src/main/resources, as com/kit/version.properties.
I have checked that the version.properties file is found inside of the jar file by running:
jar tf basictool.jar > output.txt
where i find the version.properties file as such:
resources/com/kit/version.properties
I attempt to load the resource like this:
ResourceBundle.getBundle("com/kit/version");
My machine and environment specifications are as followed:
Windows 7, Spring version: 3.7.2.
Note:
I found many questions similar to the one i have, but the answers i have found point to the properties file being properly named or placed in the correct location. From those answers i learned that version.properties is fine, since ResourceBundle.getBundle("com/kit/version") will first look for version.class then version.properties by default. It will also look for version_en_US.properties before ultimately looking for the base name version.properties.
I seem to be in line with the above, since the file version.properties is in the correct location and named correctly. I also seem to be in line with what other answers have offered :(
I would also like to point out that it finds the resource just fine when i run the program from spring, which brings me to suspect that something about the jar's creation process is the cause of the problem.
And it is also important to note that the properties file is in another maven project.
I hope i offered enough/clear details. Any help would be appreciated, thank you in advance!

If your application calls ResourceBundle.getBundle("com/kit/version"); from with in Eclipse everything works fine.
But when you create a jar file in the way you described (export -> java -> runnable jar), the version.properties is placed within the jar file at resources/com/kit/version.properties. Mind the "resources" in front of the path.
If you call this jar with java -jar basictool.jar outside Eclipse the version.properties cannot be found and java.util.MissingResourceExceptionis thrown.
If you change the path and call ResourceBundle.getBundle("resources/com/kit/version"); it won't work within Eclipse but java -jar basictool.jar will do.
It seems exporting the project from Eclipse causes the problem.
I would suggest to create the jar file to use without Eclipse with the maven-assembly-plugin.
An example can be found here.
This plugin creates a jar file without the resources directory and so the call of ResourceBundle.getBundle("com/kit/version"); works within and outside of Eclipse.
