ActionBarSherlock是一个库项目，这意味着您需要添加一个< type> apklib< / type> 到Maven依赖声明。

ActionBarSherlock is a library project which means you need to add a <type>apklib</type> to the Maven dependency declaration.

<dependency>
  <groupId>com.actionbarsherlock</groupId>
  <artifactId>actionbarsherlock</artifactId>
  <version>4.2.0</version>
  <type>apklib</type>
</dependency>

（请注意，我还更改了 artifactId 到'actionbarsherlock'）

(Note that I've also changed the artifactId to 'actionbarsherlock')

为此，您需要拥有 android-maven- < extensions> true< / extensions> 引用的插件。看来您已从粘贴的 pom.xml 完成此要求。

In order to do this, you need to have the android-maven-plugin referenced with <extensions>true</extensions>. It looks you have this requirement completed already from your pasted pom.xml.
