使用factory with assisted parameters创建实例会引发Google Guice异常

Question

public interface JobConfiguration {
    void execute();
}

public class DecryptJobConfiguration implements JobConfiguration {
    @Inject
    public DecryptJobConfiguration(@Assisted("secretKey") String secretKey,
                                   @Assisted("inputImagePath") String inputImagePath,
                                   ImageDecrypter imageDecrypter) {
        // Do stuff
    }

    @Override
    public void execute(){
        // DO stuff
    }
}

public class EncryptJobConfiguration implements JobConfiguration {
    @Inject
    public EncryptJobConfiguration(@Assisted("inputString") String inputString,
                                   @Assisted("secretKey") String secretKey,
                                   @Assisted("inputImagePath") String inputImagePath,
                                   ImageEncrypter imageEncrypter,
        // Do stuff
    }

    @Override
    public void execute() {
        // Do stuff
    }
}

public interface JobConfigurationFactory {
    @Named("encrypt")
    JobConfiguration createEncrypt(@Assisted("inputString") String inputString,
                                   @Assisted("secretKey") String secretKey,
                                   @Assisted("inputImagePath") String inputImagePath);

    @Named("decrypt")
    JobConfiguration createDecrypt(@Assisted("secretKey") String secretKey,
                                   @Assisted("inputImagePath") String inputImagePath);
}

install(new FactoryModuleBuilder()
        .implement(JobConfiguration.class, Names.named("encrypt"), EncryptJobConfiguration.class)
        .implement(JobConfiguration.class, Names.named("decrypt"), DecryptJobConfiguration.class)
        .build(JobConfigurationFactory.class));

@Inject
public CommandLineArgumentValidator(JobConfigurationFactory jobConfigurationFactory){
    this.jobConfigurationFactory = jobConfigurationFactory;
}

jobConfigurationFactory.createEncrypt("A", "B", "C");

在com.google.inject.assistedinject.FactoryProvider2.invoke(FactoryProvider2.java:824)在com.sun.proxy.$proxy12.createEncrypt（未知源）在com.infojolt.imageEncrypt.CommandLinearGumentValidator.ValidateArguments(CommandLinearGumentValidator.java:29)在com.infojolt.imageEncrypt.CommandLinearGumentValidator.java:29)在ODAccessorImpl.Invoke0（本机方法）

这是我第一次使用Google Guice。我不确定我是否误解了它的工作原理？我应该如何创建EncryptJobConfiguration的新实例？
