Todays update of the Eclipse plugin causing errors

[Stefan Eder]

I updated the eclipse plugin.

After every start of Eclipse I get this error now:

The projects contect menu is blocked and can only be invoked using [Alt]-[Return].

I am unable to open the Codename One Project settings page.

The log entries from trying to open the projects context menu are:

The designer cannot be opened, too.

Looking in the ~/.codenameone directory the designer_1.jar is still as of 1nd of January

[Chen Fishbein]

Thanks, we are looking into this.

I will update this thread once I'll have a fix this

[Chen Fishbein]

Ok, should be fixed now.

Update the plugin again, sorry for the inconvenience 

[Stefan Eder]

After update and restart of Eclipse, now the project menu opens, but without the CodenameOne entry.

Ther is still the error "java.lang.Error: Unresolved compilation problem: Override cannot be resolved to a type"

[Stefan Eder]

I cleared the log, restarted Eclipse and went into the project context menu. See the log:

[Stefan Eder]

I "found" the CodenameOne entry in the breakpoint properties of a member access breakpoint - see:

[Chen Fishbein]

What version of eclipse are you using?

[Stefan Eder]

I use the ordinary one - see:

[Chen Fishbein]

That's a strange error.

Not sure about this, I tried this new plugin on 3 different eclipse versions (including yours) and it works fine.

can you try this: (found it somewhere on the net)

Windows–>Preferences–>Java–>Compiler–>Building–>Output folder–>”Rebuild class files modified by others”.

Then try restart the IDE

[Stefan Eder]

That worked. Thanks
