Android的测试java.lang.NoClassDefFoundError的错误，由于巨星，Android的 [英] Android Testing java.lang.NoClassDefFoundError Error due to Fest-Android

问题描述

我目前正在实施巨星为Android到我的项目，但我似乎遇到了依赖问题。如果我跑我的测试，而不包括巨星库，测试将照常运行。有一次，我在巨星库中添加则测试不再运行。一个例外是，而不是抛出。

I'm currently implementing Fest for Android into my project but I seem to be running into a dependency issue. If I run my tests without the Fest library included, the tests will run as normal. Once I add in the Fest library then the tests no longer run. An exception is thrown instead.

我的项目使用下面的依赖关系：

My project uses the following dependencies:

compile files('libs/robotium-solo-5.1.jar')
androidTestCompile 'com.squareup:fest-android:1.0.8'
androidTestCompile 'com.google.code.gson:gson:2.2.4'
androidTestCompile 'com.jayway.android.robotium:robotium-solo:5.1'
androidTestCompile 'com.google.mockwebserver:mockwebserver:20130706'
androidTestCompile 'com.google.dexmaker:dexmaker:1.0'
androidTestCompile('com.google.dexmaker:dexmaker-mockito:1.0') {
    exclude module: 'hamcrest-core'
    exclude module: 'objenesis'
    exclude module: 'mockito-core'
}
androidTestCompile 'org.mockito:mockito-all:+'

我试过不包括我下面列出的巨星Android的依赖，但对测试的运行没有影响。

I've tried excluding the Fest Android dependencies that I've listed below but it has no effect on the running of the tests.

androidTestCompile ('com.squareup:fest-android:1.0.8') {
    exclude group: 'com.google.android', module: 'android'
    exclude group: 'com.google.android', module: 'support-v4'
    exclude group: 'org.easytesting', module: 'fest-assert-core'
}

这是包括当测试与巨星库运行发生异常。

This is the exception that is occurring when the tests are run with the Fest library included.

Any help or suggestions would be greatly appreciated.

推荐答案

您有两个问题在这里：

1. 您正在编制robotium的两个版本到您的项目，这样你就可以删除其中的一个。

1. You are compiling two versions of robotium into your project, so you can remove one of them.

FEST-的Andr​​oid已经支持-V4库的依赖关系，所以你需要排除，就像你不包括hamcrest芯'从'dexmaker-的Mockito'的依赖。你可以看到所有的依赖从 FEST-Android的依赖。

FEST-Android already has a dependency of support-v4 library so you will need to exclude that just like you are excluding 'hamcrest-core' from the 'dexmaker-mockito' dependency. You can see all of its dependencies from FEST-Android Dependencies.

我会建议您做如下更改您的依赖关系。

I would recommend that you make the following changes to your dependencies.

// Testing Libraries
androidTestCompile('com.squareup:fest-android:1.0.8') {
    exclude module: 'support-v4'
}
androidTestCompile('com.google.code.gson:gson:2.2.4')
androidTestCompile('com.jayway.android.robotium:robotium-solo:5.1')
androidTestCompile('com.google.mockwebserver:mockwebserver:20130706')
androidTestCompile('com.google.dexmaker:dexmaker:1.0')
androidTestCompile('com.google.dexmaker:dexmaker-mockito:1.0') {
    exclude module: 'hamcrest-core'
    exclude module: 'objenesis'
    exclude module: 'mockito-core'
}
androidTestCompile('org.mockito:mockito-all:+')

正如你可以看到我已经删除，你有额外的robotium依赖，我也排除了模块的的支持-V4的。这应该可以有你回来在任何时间运行测试！ :-D

As you can see I have removed the extra robotium dependency that you had and I have also excluded the module 'support-v4'. Hopefully this should have you back running tests in no time! :-D
