Eclipse — Testng references non-existing project XXX, launch configuration

Question

When trying to run a test as a TestNG suite, I would get a very cryptic error message saying that TestNG can\'t launch because it references a non-existant project. I think

Answer 1

In my case, the error occurred in a Scala project. It had installed the eclipse plugin, but it had not been used yet.

Diagnostics: If all goes well, the project has a blue S for scala project. If not, it has a yellow PC mouse (for whatever that means).

To fix, you need to

sbt eclipse

on the command-line. Eclipse recognizes it as Scala project at the latest on restart.

Answer 2

In my case the run shortcut was referencing an old project.

Simply right clicking on the folder of the project I was trying to run and selecting my java class fixed the problem.

After that pressing the run button started working again.

Answer 3

It doesn't have to be a Java Project, it could be a Maven one as well. There could be a reference problem with the oldest version of the project. Please try deleting the oldest version from your Eclipse workspace, and then change your reference point.

Solved in a different way for the same issue.

1) Go to Project->properties.

2) In properties window's left pane select "Project Facets".

3) Then click on "Convert to faceted form"

Apply and Close.

Note: Verify the project and the default IDE JRE is same version.
