MyEclipse8.5的Help菜单下没有Software Updates的设置方法

Using the classic update manager

In some situations you may not be able to install or update software using the menu commands in the Help menu. In these situations you will automatically be redirected to the classic update manager. You can also access the classic update manager from the General > Capabilities preference page by enabling the Classic Update capability. When this capability is enabled, a Software Updates... sub-menu will appear in the Help menu, providing access to classic update commands.
