[Bug 1479088] New: cdtdebug cannot start: java.lang.ClassNotFoundException : org.eclipse.core.runtime.adaptor.EclipseStarter

https://bugzilla.redhat.com/show_bug.cgi?id=1479088

Bug ID: 1479088
           Summary: cdtdebug cannot start:
                    java.lang.ClassNotFoundException:
                    org.eclipse.core.runtime.adaptor.EclipseStarter
           Product: Fedora
           Version: 26
         Component: eclipse-cdt
          Assignee: [e-mail]
          Reporter: [e-mail]
        QA Contact: [e-mail]
                CC: [e-mail],

                    [e-mail], [e-mail]

Description of problem:
I cannot start cdtdebug at all.

Version-Release number of selected component (if applicable):
eclipse-swt-4.7.0-2.fc26.x86_64
eclipse-cdt-9.3.0-0.3.gitbfe45e8.fc26.x86_64
gtk3-3.22.17-2.fc26.x86_64
glib2-2.52.3-1.fc26.x86_64
java-1.8.0-openjdk-1.8.0.141-1.b16.fc26.x86_64
gdb-8.0-20.fc26.x86_64

How reproducible:
always

Steps to Reproduce:
1. Start cdtdebug (by command line or from its menu entry)

Actual results:
Does not start. Instead I get an error message dialog:
> Eclipse
> An error has occurred. See the log file
> …

The log file contains nothing but these lines:
> !SESSION [Date] [Time] [Timezone] 2017 -----------------------------------------
> !ENTRY org.eclipse.equinox.launcher 4 0 [Date-Time]
> !MESSAGE Exception launching the Eclipse Platform:
> !STACK
> java.lang.ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter
>    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)

>    at org.eclipse.equinox.launcher.Main.run(Main.java:1499)
>    at org.eclipse.equinox.launcher.Main.main(Main.java:1472)

Expected results:
Start fine.

Additional info:
Starting with the "-clean" command line option does not work around this bug,
nor does deleting the ~/fctdebugger folder or the ~/.eclipse or ~/.swt or
~/.cache/eclipse folder.

Hmm, I cannot reproduce this on my F26 machine.

What if you tried a fresh workspace? For example:

$ cdtdebug -data workspace-$(date -u +%Y%m%d%H%M%S)

What other eclipse packages do you have installed? Maybe I need to replicate
your install more precisely.

Bug is still present. Command line output:

Oh, that's interesting. Maybe the launch script is doing something wonky. Can
you please try invoking like this and attaching the stderr output, e.g.:

$ bash -x /usr/bin/cdtdebug 2> logfile

It looks like this problem is related to the fact that I have an executable
file at /usr/local/bin/eclipse with this content (not quoted, of course):
> #!/bin/sh
> export GTK_THEME=Adwaita:light
> /usr/bin/eclipse $@

--- Comment #5 from Christian Stadelmann  ---
After removing /usr/local/bin/eclipse, running

$ LC_ALL=C bash -x /usr/bin/cdtdebug 2> logfile2

works fine. The other command

$ LC_ALL=C cdtdebug -data workspace-$(date -u +%Y%m%d%H%M%S)

also works fine after cd'ing to a folder I can write to.

--- Comment #6 from Mat Booth  ---
Yep, your script causes the output of "which eclipse" to be something that
cdtdebug does not expect.

I suppose it is safe these days for cdtdebug to always assume that the eclipse
executable lives in /usr/lib/eclipse
