Bug ID: 1331470 Summary: swt hello world tutorial does not work Product: Fedora Version: 23 Component: eclipse Severity: medium Assignee: akurtako@redhat.com Reporter: rtc@helen.plasma.xg8.de QA Contact: extras-qa@fedoraproject.org CC: akurtako@redhat.com, andjrobins@gmail.com, eclipse-sig@lists.fedoraproject.org, jerboaa@gmail.com, krzysztof.daniel@gmail.com, mat.booth@redhat.com, rgrunber@redhat.com
Description of problem: The "Create a Hello World SWT application" fails to work as described; widget classes are inaccessible.
Version-Release number of selected component (if applicable): eclipse-platform-4.5.2-10.fc23.i686
How reproducible: always
Steps to Reproduce: 1. run eclipse 2. On the welcome tutorial screen, select "Create a Hello World SWT application" 3. do as instructed
Actual results: "Organize imports" has no effect, which leads to the following compile errors: Display cannot be resolved to a type Display cannot be resolved to a type Shell cannot be resolved to a type Shell cannot be resolved to a type
Expected results: imports for Display and Shell are added by the "Organize imports" command.
Additional info: 1. manually adding the necessary imports, like
import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell;
has no effect; the compile errors about missing Display and Shell are still present.
2. The workspace explorer shows some strange files in org.eclipse.swt.gtk.linux.x86, like org/eclipse/swt/widges/*.orig and library/*.orig. Should these files really be there? They look like leftover files from a patch that was applied.

You are right, these files should not be there are left overs from a patch that is not cleanly applied (there was fuzz) but this likely to be a red herring and not the cause of your problem.
Fortunately, our SWT patches go away with the update to Neon. :-)

I confirm it is not working. We're thinking it may have something to do with the way we package the org.eclipse.swt.gtk.linux.x86_64 project in fedora as it is working fine with upstream eclipse.

--- Comment #4 from Sopot Cela scela@redhat.com --- Created attachment 1152185 --> https://bugzilla.redhat.com/attachment.cgi?id=1152185&action=edit Screenshot
The issue is narrowed down to two jars not being present in org.eclipse.swt.gtk.linux.x86_64. See attachment for a comparison of fedora and upstream versions (left-fedora and right-upstream). They are in the upstream version but they're not in the fedora case. Also deleting the jars in upstream project gives same erroneous behavior (imports not resolved).

--- Comment #5 from Alexander Kurtakov akurtako@redhat.com --- Hmm, having the jars embedded that way looks wrong in the upstream version. And all the class files should be there already so I would say the example/whatever is run by the hyperlink needs fixing to setup the project proper.

--- Comment #6 from Fedora End Of Life jkurik@fedoraproject.org --- This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
