更新Intelij在線程「main」中獲取異常java.lang.NoClassDefFoundError：org/testng/TestNG

Question

更新intelij後，我無法再運行testng.xml。 如果我作爲一個單獨的類運行我的測試它工作正常，並運行。但是，如果我將它作爲套件Testng.xml運行，則會出現錯誤。

我的搖籃配置：

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 '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

。
並給出消息：

我有同樣的問題，「安東安東」報道，當我跑一個特定的單元測試。但是，當我用mvn clean test運行整個套件時，這並沒有發生。

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

我遇到了這個blog post in the IntelliJ Community這對我有用。

"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."

向Serge Baranov和Leonardo Hernandez致謝。
