[cross-project-issues-dev] Strange Problems with

[Ed Merks]

Hi,

I'm having strange Tycho build problems when using
http://download.eclipse.org/eclipse/updates/4.10-I-builds and was hoping
someone might have an idea.

Otherwise identical builds that are using
http://download.eclipse.org/eclipse/updates/4.9-I-builds work fine.

I see log entries like this when building:

[INFO] Adding repository http://download.eclipse.org/releases/2018-12

Hunting around a bit, I think its probably because of these touchpoint
instructions in the p2 metadata for the 4.10-I-Builds:

          <instruction key='configure'>
addRepository(type:0,location:http${#58}//download.eclipse.org/eclipse/updates/4.10,name:The
Eclipse Project
Updates);addRepository(type:1,location:http${#58}//download.eclipse.org/eclipse/updates/4.10,name:The
Eclipse Project
Updates);addRepository(type:0,location:http${#58}//download.eclipse.org/releases/2018-12,name:2018-12);addRepository(type:1,location:http${#58}//download.eclipse.org/releases/2018-12,name:2018-12);mkdir(path:${installFolder}/dropins);
          </instruction>

I think that leads to strange errors like this:

ERROR] Failed to execute goal
org.eclipse.tycho.extras:tycho-eclipserun-plugin:1.0.0:eclipse-run
(default) on project org.eclipse.emf.activities: Execution default of
goal org.eclipse.tycho.extras:tycho-eclipserun-plugin:1.0.0:eclipse-run
failed: Failed to load p2 repository with ID 'juno' from location
http://download.eclipse.org/releases/2018-12: No repository found at
http://download.eclipse.org/releases/2018-12. -> [Help 1]

But I have other strange errors as well that suggest SWT is somehow missing:

[ERROR]
D:\sandbox\USER-HOME\emf-2.16-master\git\org.eclipse.emf\examples\org.eclipse.emf.examples.databinding.project.ui.rcp\src\org\eclipse\emf\example\databinding\project\ui\rcp\handlers\CreateCommittershipHandler.java:[1]
[ERROR] /**
[ERROR] ^
[ERROR] The type org.eclipse.swt.widgets.Shell cannot be resolved. It is
indirectly referenced from required .class files
[ERROR]
D:\sandbox\USER-HOME\emf-2.16-master\git\org.eclipse.emf\examples\org.eclipse.emf.examples.databinding.project.ui.rcp\src\org\eclipse\emf\example\databinding\project\ui\rcp\handlers\CreateCommittershipHandler.java:[18]
[ERROR] import org.eclipse.swt.widgets.Shell;
[ERROR] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

So although the dependencies all resolved, there's perhaps something
wrong with the repo structure...

*Perhaps the problem will go away if someone creates an empty repo
located at http://download.eclipse.org/releases/2018-12.*
