I am trying to automatically hit our update site when I launch our
application. I can get to it and browse all of the features, but when I
try to install the feature I get an UnsupportedOperationException. Here
is the code:
feature.install(feature, new FeatureInstallVerifyListener(), new
NullProgressMonitor());
Any ideas? Am I going about this completely wrong?
The javadoc for IFeature.install(...) states:
"Install the contents of this feature into the specified target feature.
All optional features will be installed"
What is the target feature supposed to be? I think that is screwing me
up, but I am not sure. The full code is below.
Thanks in advance,
-Phil
try {
String featureID = "foo.bar";
ISite site = SiteManager.getSite(new
URL("http://foo.com/bar"), new NullProgressMonitor());
ISiteFeatureReference[] featureReferences =
site.getFeatureReferences();
IFeature remoteFeature = null;
for (int x = 0; x < featureReferences.length; x++) {
if
(featureReferences[x].getVersionedIdentifier().toString().st artsWith(featureID
+ "_")) {
remoteFeature = featureReferences[x].getFeature(new
NullProgressMonitor());
break;
}
}
if (remoteFeature == null) {
throw Utilities.newCoreException(
"The com.amirsys.acresconsole feature could not be
found on this update site.",
null);
}
PluginVersionIdentifier remoteVersion =
remoteFeature.getVersionedIdentifier().getVersion();
PluginVersionIdentifier localVersion = null;
IPlatformConfiguration platformConfiguration =
BootLoader.getCurrentPlatformConfiguration();
IPlatformConfiguration.IFeatureEntry[] localFeatures =
platformConfiguration.getConfiguredFeatureEntries();
for (int x = 0; x < localFeatures.length; x++) {
if
(localFeatures[x].getFeatureIdentifier().toString().startsWi th(featureID
+ "_")) {
localVersion = new
PluginVersionIdentifier(localFeatures[x].getFeatureVersion() );
}
}
if (localVersion == null ||
remoteVersion.isGreaterThan(localVersion)) {
System.out.println("[CorePlugin] updating from version
" + localVersion + " to version " + remoteVersion);
System.out.println("[CorePlugin] installing...");
remoteFeature.install(remoteFeature, new
FeatureInstallVerifyListener(), new NullProgressMonitor());
System.out.println("[CorePlugin] ...installed");
} else {
System.out.println("[CorePlugin] Your system is up to
date!");
}
} catch (MalformedURLException e) {
log("", e);
} catch (CoreException e) {
log("", e);
}

Philip, what eclipse version are you using/
In 3.0 you can use the new org.eclipse.update.operations package for
programmatically installing features, or even the classes in the
org.eclipse.update.standalone.

I think there are two kind of features, remote features (those you get from
an update site), and target features, which are the features created by
installing a remote feature locally.
The API layer you are using is very low level and error prone. Use
org.eclipse.update.operations or org.eclipse.update.standalone.
If you don't want to use the standalone commands, you can at least look at
the code and see how they call the operations layer.
The update code works kind of like
Update UI Standalone commands for update/install/etc. operations

Two problems with the code below:
1. if you update an existing feature, you must first disable the old one.
Lots of gory details you need to wory about...
2. the first argument should be TargetFeature, basically a feature that
supports the install operation. The remote feature is used as a source for
the install operation.
