方式一：替换Eclipse的配置文件
其实Eclipse的各种配置都是在文件设置里的，因此只要用一个配置好的模版来替换默认的配置文件，即可将所有配置克隆到新的Eclipse环境中。这些配置文件在workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings文件夹下。
懒人直接上代码：文件org.eclipse.ui.editors.prefs：
AbstractTextEditor.Color.Background.SystemDefault=false

AbstractTextEditor.Color.Foreground=,,
