导入项目style.xml报错No resource found that matches the given name: attr 'colorAccent'

eclipsse导入项目后，style.xml下报错：
No resource found that matches the given name: attr 'colorAccent'
No resource found that matches the given name: attr 'colorPrimaryDark'
No resource found that matches the given name: attr 'colorAccent'

style.xml代码如下：

<!-- Base application theme. -->
<style name="AppTheme" parent="AppTheme.Base"/>
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

appcompat_v7包都已经导入，是不是sdk版本的问题

我也想知道
