Error with Papyrus Java CodeReverse (again) [message #1859806]

Hello,

I am facing the same problem as explained in
https://www.eclipse.org/forums/index.php/m/1838339/?srch=AbstractUIPlugin#msg_1838339

I have installed Designer 2.1.0 and when I trigger "right click > Java > Java Reverse", no "Preferences > Papyrus > Java Code Reverse" is opened.

error.log file is showing this message:
Caused by: java.lang.ClassNotFoundException: org.eclipse.ui.plugin.abstractuiplugin cannot be found by org.eclipse.papyrus.designer.languages.java.reverse.ui_1.1.0

I know where is a known bug
<569957 - ClassNotFoundException: AbstractUIPlugin for "Java Profile, Library and Code Generation"> dated December 2021 and it seems it has been solved with "current release" (cf. https://bugs.eclipse.org/bugs/show_bug.cgi?id=569957)

But which release ? Papyrus release or Designer release ?

Is there a more recent version of Designer which is fixing this bug ?

Where can I found Designer or Papyrus release (maybe a nightly build) for which Java reverse is working ?

Thank you for your attention.

Didier

Hi,

you can find version information for Papyrus SW designer on the getting started wiki page. Current version is 3.0.0.
There is also some information about the compatibility between SW designer and Papyrus versions.

Hello,

Thank you very much for theinformation you gave

I have installed SW Designer using "Artifacts of papyrus-designer-2023-03 " repository as mentioned in getting started wiki page.

Unfortunately when I run Papyrus, Error Log is showing the following error messages:

Plug-in org.eclipse.papyrus.designer.languages.java.reverse.ui was unable to load class org.eclipse.papyrus.designer.languages.java.reverse.ui.dnd.ReverseJobAndTransactionalDropStrategy.
...
Caused by: java.lang.NoClassDefFoundError: org/eclipse/ui/plugin/AbstractUIPlugin
...
Caused by: java.lang.ClassNotFoundException: org.eclipse.ui.plugin.AbstractUIPlugin cannot be found by org.eclipse.papyrus.designer.languages.java.reverse.ui_1.0.5

It looks like I have installed an older version of ,reverse_ui (1.0.5 insted of 1.1.0) and the same problem occured as before.

Thus I am still not able to use reverse engineering for my java package.

Nevertheless thank you for your support.

Hello,

At last I chose to upload a nightly build #1441 at getting started wiki page and I succeeded to get all the stuff this time (which was not the case up to know due to a poor slow connection).

And it seems now that the problem with AbstractUIPlugin disappeared.

I must practice with papyrus-designer sutdio to reverse my java code but today I am confident.

thank you very much again for your help.

Best regards.

Didier
