如何让 Powermock 与 Dexmaker 一起工作

我正在尝试使用以下版本将 :

<块引用>

PowerMock 使用自定义类加载器和字节码操作来模拟静态方法、构造函数、最终类和方法、私有方法、删除静态初始化器等等.

那个自定义类加载器不太可能在 dalvikvm 上工作.

I am trying to incorporate Powermock as a dependency for my Android tests using the following build.gradle configuration:

dependencies{
    compile 'com.android.support:appcompat-v7:21.0.+'
    androidTestCompile('org.mockito:mockito-core:1.9.5')
    androidTestCompile('com.google.dexmaker:dexmaker:1.2')
    androidTestCompile('com.google.dexmaker:dexmaker-mockito:1.2')
    androidTestCompile('org.powermock:powermock-module-junit4:1.5.5') {
        exclude module: 'junit'
    }
    androidTestCompile('org.powermock:powermock-api-mockito:1.5.5') {
        exclude module: 'mockito-all'
    }
}

However, the compiler is complaining that

Error:Gradle: Execution failed for task ':app:packageDebugTest'.

Looking into the jar structure, I noticed that both Dexmaker and Powermock declare a MockMaker in mockito-extensions

What is a MockMaker? How do they differ? And the most important question: Is it possible to get Powermock to work nicely with Dexmaker?

Thanks in advance. Any help would be greatly appreciated.

MockMaker is a glue module that integrates dexmaker with Mockito. It does what's necessary for Mockito to generate concrete classes with Dalvik .dex files instead of JVM .class files.

It's possible that Powermock will work with Dexmaker, but it's unlikely advanced Powermock features will work. In particular, Powermock advertises this:

PowerMock uses a custom classloader and bytecode manipulation to enable mocking of static methods, constructors, final classes and methods, private methods, removal of static initializers and more.

That custom class loader is unlikely to work on dalvikvm.
