更新Intelij在线程“main”中获取异常java.lang.NoClassDefFoundError：org/testng/TestNG

Question

更新intelij后，我无法再运行testng.xml。 如果我作为一个单独的类运行我的测试它工作正常，并运行。但是，如果我将它作为套件Testng.xml运行，则会出现错误。

我的摇篮配置：

group 'ao-core-android' 
version '1.0-SNAPSHOT' 


apply plugin: 'java' 

sourceCompatibility = 1.5 

tasks.withType(Test) { 
    scanForTestClasses = false 
    include "**/*Test.class" // whatever Ant pattern matches your test class files 
} 

test { 
    useTestNG { 
     suites 'testng.xml' 
    } 
} 


repositories { 
    mavenCentral() 

} 

dependencies { 
    //testCompile group: 'junit', name: 'junit', version: '4.11' 
    compile 'org.testng:testng:6.9.10' 
    compile 'io.appium:java-client:4.0.0' 
    compile 'org.seleniumhq.selenium:selenium-java:2.53.1' 
    compile 'com.android.tools.build:gradle:1.1.0' 
    compile fileTree(dir: 'externalLibs', include: ['*.jar']) 
    compile files('./lib-test-tools-1.4.0.jar') 
} 

它突出了

test { 
    useTestNG { 
     suites 'testng.xml' 
    } 
} 

中的build.gradle

。
并给出消息：

我有同样的问题，“安东安东”报道，当我跑一个特定的单元测试。但是，当我用mvn clean test运行整个套件时，这并没有发生。

Exception in thread "main" java.lang.NoclassDefFoundError: org/test/TestNG 

我遇到了这个blog post in the IntelliJ Community这对我有用。

"I got it to work by selecting "In whole project" (I had "In single module" selected) under the Configuration tab in the TestNG "Run/Debug Configurations."
