Situation:
I have an Eclipse RCP Application, which I am trying to build with tycho plugin for Eclipse.
When I am executing my Eclipse Application inside of the IDe – the Application is executed normally.
When using tycho to build the Application – the following error is thrown:

The type org.eclipse.swt.widgets.Button cannot be resolved. It is indirectly referenced from required .class files

What I did :
In other cases where a “missing requirenments” exception was thrown, which I found
– a missing transitive plugin-dependency was the reason.

In my case an SWT widget “Button” is missing, so I am trying to import swt.
SWT is platform dependant so I am importing swt inside of the product, as described here.

Anyway, during compilation the error occurs again.

Question:
Do someone have any Idea, how to solve this Problem?

    I got the answer from the mailing list (Thnx Jeff MAURY!) – it seems to be a bug of tycho.
    Here is a patch available.

    For those, who do not know GIT yet, like me:

    • When checking out the patch on windows use TortoiseGit or MSYGit clients, not the EGit Client – it wont recognize the repository.
    • Additionally use the https repository, not the git repository – git didn’t work for me
    • And the checkot syntax is git clone https://git.eclipse.org/r/tycho/org.eclipse.tycho.git – https://git.eclipse.org/r/tycho/org.eclipse.tycho.git is the repository URL here
