Hi,
I am migrating our plug-in project from 2.1 to 3.0. I have used the PDE
migration tool, after that everything seems fine. My plug-in works fine
except there are some warnings at compile time with regard to deprecated
functionalities in 3.0.
So I started to change my code to get rid off the warnings, one of them is
the plugin constructor:
It's used to be:
public class MyPlugin extends Plugin
{
....
private static MyPlugin s_plugin;
....
/**
* Constructor for MyPlugin.
*/
public CAHCorePlugin(IPluginDescriptor descriptor)
{
super(descriptor);
s_plugin = this;
}

public MyPlugin(IPluginDescriptor descriptor)
{
super(descriptor);
s_plugin = this;
}
Since IPluginDescriptor and the constructor MyPlugin(IPluginDescriptor)
are deprecated, I changed the above to:
public class MyPlugin extends Plugin
{
....
private static MyPlugin s_plugin;
....
/**
* Constructor for MyPlugin.
*/
public MyPlugin()
{
super();
s_plugin = this;
}
After the change, the project is built fine. But at run time, eclipse is
not able to initiate my plugin, it seems eclipse is still looking for the
older constructor, I know I may missing something trivial here, but what
am I missing?
Following is the error dump in eclipse:

Try launching Eclipse with -clean.
