I replace powermock-module-junit4-rule to powermock-module-junit4-rule-agent slove this issue.

@stoneCrystal Thanks for the comment.
I got same error as you reported. Then followed your solution and replaced testCompile "org.powermock:powermock-module-junit4-rule:${PowerMockito}" by testCompile "org.powermock:powermock-module-junit4-rule-agent:${PowerMockito}". However I'm getting new error:

java.lang.ExceptionInInitializerError
    at com.grabtaxi.passenger.sdk.db.dao.RealmPOIManagerTest.<init>(RealmPOIManagerTest.java:47)

Which is pointing to @Rule in

public class RealmPOIManagerTest
{
    @Rule
    public PowerMockRule rule = new PowerMockRule();

@stoneCrystal same problem for me on version 1.6.4 of powermock.

using below dependencies in my pom.xml:

<dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-module-junit4</artifactId>
            <version>${powermock.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-api-mockito</artifactId>
            <version>${powermock.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-module-junit4-rule-agent</artifactId>
            <version>${powermock.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-classloading-xstream</artifactId>
            <version>${powermock.version}</version>
            <scope>test</scope>
        </dependency>

BaseTest class has RunWith annotation with following param in it: @RunWith(SpringJUnit4ClassRunner.class)

and the class which has tests has following annotation on class:

@PowerMockIgnore( { "org.springframework.*", "org.apache.log4j", "org.mockito.*" })
@PrepareForTest({MyStaticClass.class})
public class MyTest extends BaseTest

then gettign error at the line:

 @Rule
public PowerMockRule rule = new PowerMockRule();
