Eclipse 4.10 不支持降级到Eclipse Neon所需的TestNG插件
TestNG仅适用于（4.9）2018-09之前的版本，您没有为2018-12插入插件，因此未显示在市场中
解决方案
I必须从 http://beust.com/eclipse/ 手动（不使用市场）TestNG版本p>
注意有关您正在安装包含未签名内容的软件的警告
I'm using Eclipse 4.9, I tried to update new TestNG upgrade(7)
It failed so I rollback to previous version and now I have an issue
'Invalid classpath container: 'TestNG' in project
I can't fix it by
clean project (maven can't be execute due to NullpointerException below errors)
Reinstall TestNG
Remove and add TestNG library
I didn't find relevant answers for this issue

EDIT 2
Eclipse 4.10 doesn't support TestNG plugin to needed to downgrade to Eclipse Neon
TestNG is only available only for version till (4.9)2018-09 , you hv not made plug in for 2018-12.that's why it is not showing in marketplace
解决方案
I had to manually (not using marketplace) TestNG version from http://beust.com/eclipse/
Notice there's warning about You are installing software that contains unsigned content
