Preselect default workspace location in Eclipse Launcher [message #1746284]

I know that I can use the -data argument in the Eclipse.ini to force Eclipse to always use the given directory. This is not flexible enough for me. Is it also possible to prepropagate the "Workspace" drop down in the Eclipse Launcher with the default workspace location? How do I achieve that?
Thanks,
Konrad

The configuration setting for this is stored (on a Mac) below

Eclipse.app/Eclipse/configuration/.settings/org.eclipse.ui.ide.prefs

and read out in the code via

new ScopedPreferenceStore(ConfigurationScope.INSTANCE,
IDEWorkbenchPlugin.IDE_WORKBENCH);

.
Can I use the setup:PreferenceTask to write values to this PreferenceStore. If yes, what of key do I have to provide for scope ConfigurationScope.INSTANCE?

Well you could use a preference task, but the preference task must run in the IDE where the preference is to be set, so of course by then it's to late to change the workspace. You can manipulate the file where it's stored directly. That's what this task that's in each project catalog does:

<?xml version="1.0" encoding="UTF-8"?>
<setup:ResourceCreationTask
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup="http://www.eclipse.org/oomph/setup/1.0"
    content="MAX_RECENT_WORKSPACES=5&#xD;&#xA;RECENT_WORKSPACES=${workspace.location|property}&#xD;&#xA;RECENT_WORKSPACES_PROTOCOL=3&#xD;&#xA;SHOW_WORKSPACE_SELECTION_DIALOG=true&#xD;&#xA;eclipse.preferences.version=1"
    targetURL="configuration:/.settings/org.eclipse.ui.ide.prefs"/>

So if you're provisioning a project setup, this should already be happening automatically...

Found out that /conference/ is the right prefix (https://www.eclipse.org/forums/index.php/t/1069172/). For further information look at http://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fcore%2Fruntime%2Fpreferences%2FConfigurationScope.html.. So just using the key

/configuration/org.eclipse.ui.ide/RECENT_WORKSPACES

with key

${workspace.location}

works.
In addition the key

 /configuration/org.eclipse.ui.ide/RECENT_WORKSPACES_PROTOCOL

has to be set to 3.
