Eclipse plug-in RCP failing while exporting [message #299521]

Hello there,

I have a project which is running well inside Eclipse, but as soon as I am
exporting it to a directory outside of Eclipse it says:

1. ERROR in D:\eclipse3.1WTP0.7Sysdeo31b\project1\packg\xyz.java
(at line 25)
import org.eclipse.ui.forms.FormColors;
^^^^^^^^^^^^^^^^^^^^
The import org.eclipse.ui.forms cannot be resolved

I am importing this class in a jar to the project. I have tried to
signalise this in many places in the plug-in configuration files without
success. Why is the wizard not including the external jars?
I tried to add the jars to the target directory manually also
unsuccessfully...

any ideas?

PS: I tested exporting before adding the class with the import and it
worked.

Thanks

The simplified view: You cannot use external jars with plugins. A
plugin contains everything classpath related in itself, or gets it from
it's required plugins.

If you are using the form stuff, you need to open the manifest file, go
to the Dependancies tab, and add org.eclipse.ui.forms (and any other
plugins you require) in the Required Plugins section.

Thanks Paul!

I had to add it first to the xxxx.product and then as you said in the
manifest.
It failed to compile when I only had it in the manifest...
