How to use ant delete exclude attribute

From http://ant.apache.org/manual/CoreTasks/delete.html

Example:

<delete dir="${dist}">    <include name="**/images/*"/>    <exclude name="**/*.gif"/></delete>

The path is the issue where the files is not excluded.

Before the problem was solved, I used the wrong path:

<delete dir="${package}" exclude="${package}/${build.type}/XXXGame/**"/>

And it should be 

    <target name="clean">
        <delete dir="${classes}"/>
        <delete dir="${package}">
   <exclude name="**/XXXGame/**"/>


        </delete>
        <delete file="${jar}"/>
        <delete dir="${test.reports}"/>
    </target>

    <target name="clean">
        <delete dir="${classes}"/>
        <delete dir="${package}" includeEmptyDirs="true">   //Whether to delete empty directories when using filesets.
   <exclude name="**/Game1/**"/>
   <exclude name="**/Game2/**"/>
   <exclude name="**/Game3/**"/>
   <exclude name="**/Game4/**"/>
        </delete>
        <delete file="${jar}"/>
        <delete dir="${test.reports}"/>
    </target>
