InvalidUseOfMatchersException exception using PowerMockito to call static method with String array argument

[rajmaria]

Hi there,

org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Misplaced argument matcher detected here:

I am facing the org.mockito.exceptions.misusing.InvalidUseOfMatchersException exception while doing powermockito on following static method
public class ShellCommandUtil {
public static ArrayList executeShellCommand(String[] shellcmd) {
ArrayList output = new ArrayList();
//remove the actual logic of sending shellcommand to the system and getting the result
return output;
}}

TestMethod written is defined below

@RunWith(PowerMockRunner.class)
@PrepareForTest(ShellCommandUtil.class)
public class ShellDataTest{
@test
public void testExecuteShellCommand() {
ArrayList resultData = new ArrayList();
resultData.add("data1");
resultData.add("data2");
PowerMockito.mockStatic(ShellCommandUtil.class);
PowerMockito.when(ShellCommandUtil.executeShellCommand(Mockito.any(String[].class))).thenReturn(resultData);
}
}

Can you please help what is defined wrong here in this line

PowerMockito.when(ShellCommandUtil.executeShellCommand(Mockito.any(String[].class))).thenReturn(resultData);

In pom.xml, I have added the following dependency

org.powermock powermock-mockito-release-full 1.6.4 pom
