Bug ID: 1331470
Summary: swt hello world tutorial does not work
Product: Fedora
Version: 23
Component: eclipse
Severity: medium
Assignee: akurtako(a)redhat.com
Reporter: rtc(a)helen.plasma.xg8.de
QA Contact: extras-qa(a)fedoraproject.org
CC: akurtako(a)redhat.com, andjrobins(a)gmail.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.

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).

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(a)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.

Using Fedora 26, I solved by downloading and installing jdk from
