Texlipse preferences crash in Eclipse Photon Release (4.8.0)

[ykazakov]

Bug report

What is the current behavior?

Opening Preferences > Texlipse > Builder Settings as well as Preferences > Texlipse > Viewer Settings result in a popup message: "The currently displayed page contains invalid values"

Configuring texlipse is thus not possible.

What is the expected or desired behavior?

Preferences should be displayed in wich it is possible to set paths to latex / viewer commands

Please provide steps to reproduce:

• Install Eclipse Photon Release (4.8.0)
• Install texlipse 2.0.1 from Eclipse Marketplace
• Restart Eclipse as required
• Open Preferences > Texlipse > Builder Settings

Please describe your environment:

• TeXlipse version: 2.0.1
• Eclipse version: 4.8.0

Operating system:

• [ ] Windows
• [x] macOS
• [ ] Linux

Further details: The problem is probably caused by the crash:

Exception:java.lang.NoClassDefFoundError: org/eclipse/ui/help/WorkbenchHelp
     at org.eclipse.texlipse.properties.ViewerSettingsPreferencePage.createFieldEditors(ViewerSettingsPreferencePage.java:52)
...

and

Exception:java.lang.NoClassDefFoundError: org/eclipse/ui/help/WorkbenchHelp
     at org.eclipse.texlipse.properties.BuilderSettingsPreferencePage.addBuilderList(BuilderSettingsPreferencePage.java:185)

The likely reason is the removal of deprecated APIs from Eclipse 4.8.0.

I observe the same issue with the latest Eclipse.

The same in Windows.

I confirm this. Plus: I can't find TeXlipse wizard via File > New > Project… nor via File > Import…

Thanks for the detailed bug report! Please try the build at https://ci.eclipse.org/texlipse/job/continuous/ws/org.eclipse.texlipse-site/target/repository/ – I'll prepare a new release as soon as possible.

Thanks for the fix! Looking forward for v2.0.2.

[turesheim]

I think I'll be able to get it out before Friday. The marketplace entry has been updated to indicate that the 2.0.1 version does not work with Eclipse Photon https://marketplace.eclipse.org/content/eclipse-texlipse

Tested, works now. Thanks for the quick fix!
