Hi everyone,

Is the Netbeans plug-in still being maintained? We have Alice 3.9 installed on student stations but the plug-in seems to have to be paired with Alice 3.7. Is there a quick fix I can apply to get the students typing in Java and seeing their output in Alice 3?

Carlos,

The plugin is being maintained.
The most recent release (3.9.1.0), works with the latest NetBeans (30), as well as some recent earlier NetBeans versions.

The plugin does require the use a JDK 21 or higher that bundles JavaFX. Without this imported worlds will not run.
BellSoft Liberica has worked well.

https://bell-sw.com/?

As for typing in Java and seeing output in Alice 3, users can edit the java code created using the plugin, but we do not have a return path back to the Alice 3 IDE blocks.

My apologies, the plugin maintenance had not extended to the plugin web page.
I have now updated the page and links to reflect the current state.

As for the error file, it can contain substantive errors, but what you included looks like it is only our overly aggressive logging choices.

Hi,

I successfully created a new Alice 3 project in NetBeans but have some errors.
I attached the Alice 3 project and a screenshot of the NetBeans page.
Are you able to help?
