JavaDoc fails with "Illegal package name"-error

Question

I using eclipse and have 8 packages in my java project. I try to generate my javadoc with eclipse (Project->Generate JavaDoc).. but after I start the process the following errors appears:

javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.core.databinding.property_1.4.200.v20130515-1857.jar;C:UsersPhilworkspaceBachelor_Thesislibjunit-4.10.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\org.eclipse.text_3.5.300.v20130515-1451.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.core.runtime_3.9.0.v20130326-1255.jar;C:UsersPhilworkspaceBachelor_Thesisliblog4j-1.2.17.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\org.eclipse.jface_3.9.0.v20130521-1714.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.ui.workbench_3.105.0.v20130529-1406.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\com.ibm.icu_50.1.1.v201304230130.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.swt.win32.win32.x86_3.102.0.v20130605-1544.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\org.eclipse.equinox.registry_3.5.300.v20130327-1442.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.ui.forms_3.6.0.v20130517-0139.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\org.eclipse.osgi_3.9.0.v20130529-1710.jar;C:\Users\Phil\Desktop\BALokal\ZipsUndJars\antlr-4.2.2-complete.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.core.databinding.beans_1.2.200.v20130515-1857.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\org.eclipse.core.commands_3.6.100.v20130515-1857.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.equinox.common_3.6.200.v20130402-1505.jar;C:UsersPhilDesktopBALokalZipsUndJarseaapi.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\org.eclipse.jface.text_3.8.100.v20130515-1957.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.jface.databinding_1.6.200.v20130515-1857.jar;C:UsersPhilDesktopEclipse" javadoc: error - Illegal package name: "s\javaeclipse\eclipse\plugins\org.eclipse.core.databinding_1.4.1.v20130515-1857.jar;C:\Users\Phil\Desktop\Eclipse" javadoc: error - Illegal package name: "sjavaeclipseeclipsepluginsorg.eclipse.core.databinding.observable_1.4.1.v20130515-1857.jar -private -source 1.7 -use -version -author -splitindex controller "

Anybody have a solution for this problem? I use the WindowBuilder in Eclipse to create my GUI. It seems that all the named jar's in the errors are windowbuilder jar's.

Here is my ant file:

Edit(Solution)

With the help from the comments under my question I had solve the problem. In the path of my first build_path entry a folder was named "Eclipse's". Without an apostrophe it work's!:-)
