Hi

I am developing a plug-in for Eclipse 2.1. It uses several external
jars. It compiles in the workbench but when I run the runtime and error
message in the view. I tried added the names of jars to the plugin.xml
but still there is an error. I am not deploying the plug-in as of yet.
Any suggestions?

Don't use external JARs.

1. Copy the JARs into the root of the plugin project.
2. Open the Plugin Manifest Editor on plugin.xml.
3. Select the Runtime tab.
4. Add your JARs to the list of run-time libraries.

I have a similar problem: my plug-in also requires some jars.

I have added them in my plug-in project (using "Add JARs..." on the
Libraries tab of the Project Properties), and they are shown as jar files in
the root of the plugin project.

On the filesystem, the jar is physically located in a subfolder of the
plugin project and not in the root. Is this a problem?

Also I have added a jar in the Runtime tab of the plugin.xml.

I can compile the plugin and also launch the runtime workbench and it also

shows the action that I added.

However, when I execute the action, I get a NoClassDefFoundError on a class

that is located in the jar that I added.

Any further suggestions?

Thanks in advance,
Frank

Just found out that I need to specify the relative path for the jar file on
the Runtime tab instead of just the name of the jar file.
My guess is that I should specify as much as possible on this runtime tab
and look upon the Project Propeties libraries as information derived from
the runtime tab?

Yes, exactly. Modifying the project properties directly for a plugin
project is a sign of danger.

Go to Window > Preferences > Plug-In Development > Java Build Path
Control and make sure you have all options checked. Then, whenever you
modify your plugin manifest using the manifest editor, the Java build
path for your project will be automatically updated.

Try looking at the build.properties file. When I added our icons folder
to the bin.include build script variable they were included in the
exported plugin, and they weren't when I included them in the runtime
library.
