Eclipse exported Product file is not working. [message #1817710]

Hi Team,

I am working on Eclipse project where Ecore model is defined. On the model, I have developed a database plugin (eclipse plug-in project) where I am reading data from database (plugin functionality). For reading, a button on menu is added and on click of button in runtime eclipse, event to read happens. The plugin works when run as eclipse application.

I have created a product of this application. (windows and linux both) using export wizard. When I run product file (.exe) for the first time, on console I get "framework event error in eclipse" but product file is opened. When I try to click the button (database read, plugin functionality) in the .exe, it gives error as "org.eclipse.core.runtime.CoreException: plug-in was unable to load class" and "the proxied handler for could not be loaded "

I have added all required plug-ins in the product configuration.
What should be the issue? The button click event is not recognised and handled.

Did you add the recommended plug-in start levels in the 'configuration' tab of the product definition file?

Which version of eclipse are you using? Please provide stack-traces of the errors, from these short descriptions it is very hard to guess what is going on.

Eclipse version 2019-06 is being used. Earlier we were working on Eclipse Photon but while creating product, Antlr version issue was coming as it was expecting Antlr version 4.3 and Xtext need Antlr version 3.2. Eclipse had both but as a plugin content only one version was accepted. So changed to latest Eclipse version.

I have attached the documents having stack-trace of errors, product configuration and plugin details.

Thanks,
Snehal

The demo.handlers.ReplicationHandler class cannot be found by the class loader. Does org.abc.xyz.database have a dependency on the plug-in that provides that class? Does the packaged jar of the plug-in that provides the class contain the class (open the jar with zip)?

The project org.abc.xyz.database itself is the plugin developed. The demo.handlers.ReplicationHandler class is in that project only. For creating product, a separate product package is created.

The packaged jar of org.abc.xyz.database in the created product, has the ReplicationHandler class.
I have attached the package structure of the project.

Is the demo.handlers package exported in the manifest (runtime tab)?

Can you check that your .class file is actually in the jar?

Yes, I have .xtend file and it is already present in the jar file. I have attached screenshot also.

Hi Brian ,

Just realized, the .class files are not generated for the database plugin. There are compilation errors while doing the Export product. It says "Compilation errors occurred during the operation. A zip file containing the build logs has been generated and placed at G:\Config-Tool"

index.php/fa/36867/0/

How to remove the compilation error?

Hi Kirti.

My recommendation is to use Maven/Tycho for your builds. The Export wizard is very slow and is also very hard to diagnose when things go wrong. And it's also very slow compared to Maven/Tycho.

Thanks.

It is resolved Now. I missed .classpath and .project files to adding in Build tab. In database plugin already generated .classpath file. But not added to build tab because of that at the time of exporting product package folder database jar file have not created .class files.

It is odd that you have to include the .classpath and .project file as build targets.
- I have seen what you have warnings on your build.properties file, you should have checked them. Probably you missed including xtend-gen as source folder. (Note that these warnings are there to help you ...)
- I see that you have a libs folder. Make sure that your classpath is correctly set in the Manifest runtime tab. And that your .classpath file is consistent with your Manifest (Press 'update the classpath settings' in the Manifest overview tab).
