用mock-maker-inline来嘲弄安卓的mock-maker-inline结果在java.lang.VerifyError中为Google服务版本11.0.2，而不是10.2.6。

我一直在使用Mockito 2.2.22，但是更新到了最新(2.8.47)，看看它是否纠正了这个问题。下面提供的两种情况的堆栈跟踪。

Java版本

代码语言：javascript
复制
$ /Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/bin/java -version
openjdk version "1.8.0_112-release"
OpenJDK Runtime Environment (build 1.8.0_112-release-b06)
OpenJDK 64-Bit Server VM (build 25.112-b06, mixed mode)

极小例子

代码语言：javascript
复制
import com.google.android.gms.gcm.GcmNetworkManager;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnitRunner;

@RunWith(MockitoJUnitRunner.class)
public class UnitTest {
    private @Mock GcmNetworkManager gcmNetworkManager;

    @Test
    public void doesNothing() { /* empty */ }
}

One of the two will be used. Which one is undefined.

You are seeing this disclaimer because Mockito is configured to create inlined mocks.
You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.

编辑：

这应该在Mockito2.9.0中得到修正。资料来源：https://github.com/mockito/mockito/issues/944

如果您升级了Mockito，不应该需要下面的解决方法。

当检测不正确地在调用的方法中保留类型信息的模糊类时，可能会发生这种情况。

通过告诉JVM不要验证build.gradle中的单元测试中的类，我成功地修复了它：

代码语言：javascript
复制
testOptions {
    unitTests.all {
        jvmArgs '-noverify'
    }
}

有一些迹象表明，这是Proguard中的一个bug，您将看到它，因为GcmNetworkManager已经被Proguard混淆了。

此错误表示Java (JVM)中包含的验证器检测到一个类文件，尽管该类文件格式良好，但它包含某种类型的内部不一致或面临安全问题。

VerifyError类扩展了LinkageError类，该类用于指示那些错误情况，其中一个类依赖于其他类，而该类在编译后发生了不兼容的更改。此外，LinkageError类扩展了Error类，该类用于指示应用程序不应捕捉的严重问题。方法不能在其throw子句中声明此类错误，因为这些错误是永远不会发生的异常情况。

为了避免VerifyError，必须使用相同版本的Java编译所有类。另外，一旦您对类进行了更改，那么请确保从零开始重新编译您的项目。最后，如果您的应用程序使用了外部库，请验证是否使用了每个库的适当版本，当然，请参阅相应的javadocs，以确保所有内容都是正确的。
