Replacement for IPluginDescriptor [message #1822236]

Mon, 02 March 2020 04:23

We have eclipse plugin application build on eclipse version 4.3 which used IPluginDescriptor. Now, we want to build the same application on latest eclipse version i.e. eclipse 2019-12. While doing so we are facing issues with deprecated interface for example IPluginDescriptor.
As found from eclipse forums IPluginDescriptor was only supported by by plug-ins which explicitly require the org.eclipse.core.runtime.compatibility plug-in. But this is not used anymore as eclipse 4.6 removed it.
What is replacement for "org.eclipse.core.runtime.compatibility" or "IPluginDescriptor" in latest eclipse version 2019-12.

Below is the code that we need to modify which requires replacement of IPluginDescriptor :

IPluginDescriptor pluginDescriptor =
getRootElement().getDeclaringExtension().getDeclaringPluginDescriptor();
return pluginDescriptor.getPlugin();

Looking for your response.

Regards
Priya

You'll have to make due with methods like this one to which you can pass the names you see in the configuration elements.

org.eclipse.core.runtime.Platform.getBundle(String)

To do what? Odds are there's a cleaner way to solve whatever problem led you to the Plugin instance or the plug-in descriptor.

Below is the piece of code :

/**
* Discovers the ProviderLocation extensions and loads the pluginList
*
* @param registry The plugin registry to search for the extension
*/
private void discoverProviders(IExtensionRegistry registry)
{
IExtensionPoint myPoint =
registry.getExtensionPoint(PLUGIN_ID, PROVIDER_EXTENSION);
if (myPoint == null)
{
/* No extensions found for the ProviderLocation, no sweet. We just
* move on.
*/
return;
}

IExtension[] extensions = myPoint.getExtensions();

for (int i = 0; i < extensions.length; i++)
{
String pluginName = "";
try
{
Plugin plugin =
extensions[i].getDeclaringPluginDescriptor().getPlugin();
if (pluginList_.containsKey(plugin))
{
continue;
}
IConfigurationElement[] elements =
extensions[i].getConfigurationElements();
pluginName = elements[0].getAttribute(EXTENSION_NAME);

The line highlighted in bold is giving error as getDeclaringPluginDescriptor() has been deprecated.

Could you please suggest what can be used here??

It would be better to understand what you needed the object for, otherwise it's not clear what the answer should be.

For example, to get the plug-in ID, you can call IExtension#getContributor() and then just ask the IContributor its name. I don't know if that's what you actually needed from the Plugin or descriptor object, though.

Thanks for the suggestion. Currently it has resolved my one of compilation issue.
Another suggestion which I could need is replacement for getPluginRegistry() in below line of code or way to get appropriate value :
System.setProperty("javax.net.ssl.trustStore", Platform.getPluginRegistry().getPluginDescriptor("com.abc.xyz").find(new Path("wb-server.jks")).getPath());

I tried to use getExtensionRegistry() in place of getPluginRegistry() but could not find appropriate method which will return a String which is required for System.setProperty.

Can you provide a way to handle this?

Probably Platform.getBundle(...).getEntry(...).
