Good day! I've developed plugin. Now I want to save some data between the
sessions of Eclipse (for example, a String or int variable). How to do
this in a proper way?
Thanks.

Have a look at the ISaveParticipant mechanism. There is a good deal of help
avaialable on that.

IMHO, this is not appropriate. [message #18034 is a reply to message #18023]

I mean, where to save my data? Into eclipse/plugins/myfile.ini? Into
eclipse/plugins/myplugin/myfile.ini? Is there some common default place?
(For example, something like eclipse/configuration/config.ini or
workspace/.metadata/config.ini.)
When my plugin starts to work, it must read this data and then save new
one.

OSGi allows a bundle to store data in its private data area, which is
accessed via the BundleContext API getDataFile(String). This approach is
nice since it keeps the data private to the bundle, and the data goes
away when you uninstall the bundle.

Thanks.
The answer to my question is:
Activator.getDefault().getPreferenceStore().getString("my_key ");
...
Activator.getDefault().getPreferenceStore().setValue("my_key ", "my_value");
