Eclipse - 无效的类路径容器：项目中的'TestNG'和JUnit失败

问题描述 投票：0回答：1

我正在使用Eclipse 4.9，我试图更新新的TestNG升级（7）

它失败了所以我回滚到以前的版本，现在我有一个问题

'Invalid classpath container: 'TestNG' in project

我不能解决它

  1. 清理项目（由于NullpointerException下面的错误，maven无法执行）
  2. 重新安装TestNG
  3. 删除并添加TestNG库

我没有找到这个问题的相关答案

错误日志：

Eclipse 4.10不支持将TestNG插件降级到Eclipse Neon

TestNG仅适用于2018-09的（4.9）版本，你没有插入2018-12。这就是它没有在市场上展示的原因

最新版本支持Eclipse Photon 2018-12：
