java JUnit Eclipse VS Ant

Question

我正试图通过Ant任务启动Junit测试，如下所示：

<target name="TestDaoImpl">
        <mkdir dir="${junit.output.dir}"/>
        <junit fork="yes" printsummary="withOutAndErr">
            <jvmarg line="${conf.dir}"/>
            <formatter type="xml"/>
            <test name="my.package.TestKSLDaoImpl" todir="${junit.output.dir}"/>
            <classpath refid="My.classpath"/>
        </junit>
 </target>

在我的测试中，我使用PowerMockito，用于以下两种情况：

PowerMockito.whenNew(Convert.class).withAnyArguments().thenReturn(convert);
PowerMockito.mockStatic(MyService.class);

莫基托：

Mockito.when(convert.getXmlKsl(folder)).thenReturn(xmlStr); 

实际上，当我在Eclipse中运行测试时，我没有得到任何错误。 但当我通过Ant Task启动它时，我发现了以下错误：

org.mockito.exceptions.misusing.MissingMethodInvocationException: 
when() requires an argument which has to be 'a method call on a mock'.
For example:
    when(mock.getArticles()).thenReturn(articles);

Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
   Those methods *cannot* be stubbed/verified.
2. inside when() you don't call method on mock but on some other object.
3. the parent of the mocked class is not public.
   It is a limitation of the mock engine.

at org.powermock.api.mockito.PowerMockito.when(PowerMockito.java:495)

错误如下：

PowerMockito.mockStatic(MyService.class);

===> Mockito.when(MyService.getInstance(myId)).thenReturn(myService);

我用的是这个罐子：

JUnit 4
cglib-nodep-2.2.2.jar
javassist-3.18.1-GA.jar
mockito-all-1.9.5.jar
objenesis-2.1.jar
powermock-mockito-1.5.4-full.jar

与ant和PowerMockito有冲突吗？ 为什么eclipse可以很好地运行测试，而Ant却不能
