Cannot find Java class from standalone EOL plugin [message #1793304]

Hello everyone,

I am trying to call a java class from my EOL file as described in https://www.eclipse.org/epsilon/doc/articles/call-java-from-epsilon/
which throws me an error Type "org.eclipse.xxx.JavaClass" not found. As I am new to plugin development in general and also epsilon, I am stuck at this point. I am able to call standard tools from Epsilon such as FileSystemTool, but the custom java class I wrote do not work. Any help is appreciated.

Thanks
Milan

Hi Milan,

Could you please attach a copy of your custom tool plugin so that I can have a look?

Cheers,
Dimitris

Thank for the quick reply. Please find attached the plugin. Ans here goes the very "simple" class which I was calling from the same work space.


package org.eclipse.epsilon.examples.tools;

public class Importer {
	protected String name;
	public void setname(String name) {
		this.name= name;
	}

}

I have created dependency of org.eclipse.epsilon.common.dt and an extension point with attribute class org.eclipse.epsilon.examples.tools.Importer.

Both the plugins are in the same work space.

Cheers
Milan

Hi Milan,

The EOL program that uses the tool needs to be executed in a nested workspace. As state in [1]: "To invoke the tool you have two options: You can either run a new Eclipse instance, or export the plugin and place it in the dropins folder of your installation.".

Cheers,
Dimitris
