NoClassDefFoundError的：當我試圖運行使用的IntelliJ IDEA的testng.xml文件我的測試組織/ TestNG的/ TestNG的

Question

此錯誤

NoClassDefFoundError: org/testng/TestNG

出現。 運行我的測試一個個完美的作品，以及整個運行的gradle項目指向testng.xml，像grade core-test:test

（在我的項目中，我使用Appium +的IntelliJ + TestNG的）

但是，當我運行的testng.xml使用的IntelliJ壓制後，我立即收到此消息運行：

我發現了一個解決方案張貼在這裏：https://intellij-support.jetbrains.com/hc/en-us/community/posts/206597869-Cannot-launch-NGTest-runner-in-IntelliJ-IDEA-2016-1

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."

However, the prior configuration worked in IntelliJ IDEA 15, so to me, it seems that it may have come from a breaking change with newer IDE.

它爲我工作。
