我使用build.gradle并添加：

dependencies {
...
    testCompile 'org.mockito:mockito-all:1.9.5'
    testCompile 'org.powermock:powermock-api-mockito:1.5.5'

}

现在我看看我的测试类,它有：

import org.junit.Before;
import org.junit.runner.RunWith;
import org.mockito.Matchers;
import org.powermock.core.classloader.annotations.PrepareForTest;


@RunWith(PowerMockRunner.class)
@PrepareForTest(GeoUtils.class)

并得到这个错误：

@RunWith(PowerMockRunner.class)
             ^
cannot resolve symbol PowerMockRunner

如何解决PrepareForTest而不是PowerMockRunner？
