Answer 1

This happens because bintray is down and need to update the TestNG references

hi guys, because bintray.com sunset on May 1, so we have moved the update-site to github,

• new update site url: https://testng.org/testng-eclipse-update-site
• the source is at https://github.com/testng-team/testng-eclipse-update-site

we will update the url on eclipse marketplace soon.

Answer 2

For someone who is still looking for answer I ran into similar problem when installing TestNg on latest Eclipse 2021-06 Both the bintray and beust urls did not work

so I went to new update url https://testng.org/testng-eclipse-update-site copied latest Versioned update site URL https://testng.org/testng-eclipse-update-site/7.4.0

In Eclipse Help → Install new software > Add

Name: TestNg

Location: paste the copied versioned url - https://testng.org/testng-eclipse-update-site/7.4.0
