I was working Eclipse RCP application and I was configuring p2 updates for it.
I came across this example.
package org.eclipse.equinox.p2.examples.rcp.cloud.p2;
import org.eclipse.equinox.p2.engine.query.UserVisibleRootQuery; import org.eclipse.equinox.p2.examples.rcp.cloud.Activator; import org.eclipse.equinox.p2.query.QueryUtil; import org.eclipse.equinox.p2.ui.Policy; import org.eclipse.jface.preference.IPreferenceStore; import org.eclipse.swt.graphics.Point;
/** * CloudPolicy defines the RCP Cloud Example policies for the p2 UI. The policy * is registered as an OSGi service when the example bundle starts. * * @since 3.5 */ public class CloudPolicy extends Policy {
public void updateForPreferences() {
IPreferenceStore prefs = Activator.getDefault().getPreferenceStore();
setRepositoriesVisible(prefs
.getBoolean(PreferenceConstants.REPOSITORIES_VISIBLE));
setRestartPolicy(prefs.getInt(PreferenceConstants.RESTART_POLICY));
setShowLatestVersionsOnly(prefs
.getBoolean(PreferenceConstants.SHOW_LATEST_VERSION_ONLY));
setGroupByCategory(prefs
.getBoolean(PreferenceConstants.AVAILABLE_GROUP_BY_CATEGORY));
setShowDrilldownRequirements(prefs
.getBoolean(PreferenceConstants.SHOW_DRILLDOWN_REQUIREMENTS));
setFilterOnEnv(prefs.getBoolean(PreferenceConstants.FILTER_ON_ENV));
setUpdateWizardStyle(prefs.getInt(PreferenceConstants.UPDATE_WIZARD_STYLE));
int preferredWidth = prefs.getInt(PreferenceConstants.UPDATE_DETAILS_WIDTH);
int preferredHeight = prefs.getInt(PreferenceConstants.UPDATE_DETAILS_HEIGHT);
setUpdateDetailsPreferredSize(new Point(preferredWidth, preferredHeight));
if (prefs.getBoolean(PreferenceConstants.AVAILABLE_SHOW_ALL_BUNDLES))
setVisibleAvailableIUQuery(QueryUtil.ALL_UNITS);
else
setVisibleAvailableIUQuery(QueryUtil.createIUGroupQuery());
if (prefs.getBoolean(PreferenceConstants.INSTALLED_SHOW_ALL_BUNDLES))
setVisibleAvailableIUQuery(QueryUtil.ALL_UNITS);
else
setVisibleAvailableIUQuery(new UserVisibleRootQuery());
}
}
Here the type IQuery and QueryUtil are not accessible as I am not able to access the package org.eclipse.equinox.p2.query
I am using eclipse Indigo (3.7) and the dependencies I have added in my plug-in are:
org.eclipse.equinox.p2.ui.sdk
org.eclipse.equinox.p2.ui
org.eclipse.equinox.p2.engine
Kindly guide me.
You need to import org.eclipse.equinox.p2.metadata
as dependency
