Eclipse Plugin Development Tutorial

[giancarlo.capone]

Good evening to all !!!
I'm a student and I want to learn more abut the development of Eclipse
plug-in.
I was trying your tutorial : http://www.vogella.de/articles/EclipsePlugIn/article.html#contribute,
but I'm not able to make the "conversion to HTML" works.
When I right-click on the file .java and click on "Create HTML", I
can't see the HTML file.
Where can I find it ????
Thanks all .

Hi,

try F5 on your project.

Best regards, Lars

I've tried with F5, but nothing happen.
I've noticed that when I right-click on MANIFEST.MF file and click on
Run-As "Eclipse Application", I've the following errors in the
console :

I think the message is pretty clear: java.lang.ClassNotFoundException:
de.vogella.plugin.htmlconverter.Convert

Check your runtime configuration.

Thank you very much!!!

Now I have another problem :

I need a plug-in so when I right-click on a file (for example an html
file) and choose for example the Option "Modify HTML" I can open and
modify that file. I think I need only to know the path of the file
that I right-click, and so I can open that file using the class File.

The example given in the tutorial is similar, but with that code I can
only open java files.
I think the problem is ICompilationUnit that represents an entire Java
compilation unit, but I hadn't understood how I can modify that code
to re-use it.

Who can help me ????

Thanks.

Probably I don't need the path of that file, but I need each code-line
of the HTML page that I select (right-click on a file in the Package
Explorer and choose for example the option "Modify" I've created).
Does anyone know how can I write this plug-in ???
Which classes should I use to read that file ?

Thank you very much !!!

[giancarlo.capone]

I've partially resolved, but it reads only java files. I need to read
html files.

I think the problem is ICompilationUnit.

How can I resolve it ???

Thanks.
