PowerMockRule ClassNotFoundException wird ausgelöst

Question

Ich habe ein Problem mit PowerMock und Mockito-Kompatibilität.

Ich habe Testklasse:

@ActiveProfiles("test") 
@PrepareForTest(LanguageUtils.class) 
public class MyControllerTest { 

    @Mock 
    private MyMockClass MyMockClass;  
    @Autowired 
    private MyController myController; 

    @Rule 
    public PowerMockRule rule = new PowerMockRule(); 
} 

Mein POM wie folgt aussieht:

<junit-version>4.12</junit-version> 
    <hamcrest-version>1.3</hamcrest-version> 
    <mockito-version>1.10.19</mockito-version>  
    <powermock-version>1.6.4</powermock-version> 

    <dependency> 
     <groupId>org.hamcrest</groupId> 
     <artifactId>hamcrest-all</artifactId> 
     <version>${hamcrest-version}</version> 
     <scope>test</scope> 
    </dependency> 

    <dependency> 
     <groupId>org.mockito</groupId> 
     <artifactId>mockito-core</artifactId> 
     <version>${mockito-version}</version> 
     <exclusions> 
      <exclusion> 
       <artifactId>hamcrest-core</artifactId> 
       <groupId>org.hamcrest</groupId> 
      </exclusion> 
     </exclusions> 
     <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</artifactId> 
     <version>${powermock-version}</version> 
     <scope>test</scope> 
    </dependency> 

    <dependency> 
     <groupId>org.powermock</groupId> 
     <artifactId>powermock-module-junit4-rule</artifactId> 
     <version>${powermock-version}</version> 
     <scope>test</scope> 
    </dependency> 

Wenn ich versuche, Test, den ich ClassNotFoundException bekommen zu laufen. Fehler Ursache PowerMockRule, weil wenn ich diese Zeile lösche Fehler verschwindet.

Vollstacktrace wie folgt aussehen:

Dies ist ein bekanntes Problem mit PowerMock (siehe beispielsweise bug 597). Kurz gesagt, wenn Sie das Regelmodul durch das Regelagentenmodul ersetzen, sollte es den Zweck erfüllen. Das heißt, ersetzen diese Anforderung:

<dependency> 
    <groupId>org.powermock</groupId> 
    <artifactId>powermock-module-junit4-rule</artifactId> 
    <version>${powermock-version}</version> 
    <scope>test</scope> 
</dependency> 

mit:

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