卸载Eclipse插件时如何清除Preference Store中的数据？ [英] How to clear data in Preference Store when uninstalling an Eclipse plugin?

问题描述

我正在开发一个具有自己的偏好页面的Eclipse插件。
我正在使用IPersistentPreferenceStore存储一些数据，但是在卸载我的插件时要删除/清除此数据。否则，每当我重新安装插件时，我都会从以前的安装中重新加载旧数据。

到目前为止，我没有成功找到任何钩子/事件插件卸载通知我的插件。
有没有人有想法？

解决方案

一种方法是你的插件明确地将一个监听器注册到 IProvisioningEventBus 是P2的内部API。

然后，如果有事情要被删除，您的监听器将被通知如果要删除的插件是您想要的首选商店。

I'm developing an Eclipse-Plugin which has it's own preference page. I'm storing some data using IPersistentPreferenceStore, but would like to remove / clear this data upon uninstall of my plugin. Otherwise, whenever I re-install the plugin, I get the old data loaded again from previous installations.

So far I was not successful in finding any hooks / events for eclipse plugin uninstall to notify my plugin. Does anyone have an idea?

解决方案

A way is that your plug-in explicitly registers a listener to IProvisioningEventBus that is an internal API of P2.

Then your listener would be notified if something are about to be removed, clean your preference store if the to be removed plug-in is what you want.
