Getting "No project is available for evaluation" error when debugging web app using mvn jetty:run

[qianwch]

Describe the issue Could not evaluate variables when debugging web apps using mvnDebug jetty:run, But it is ok when using mvnDebug tomcat7:run.

To Reproduce Steps to reproduce the behavior:

1. Open the sample project.
2. run mvnDebug jetty:run
3. run "CocCommand java.debug.vimspector.start", to open the debugger
4. Set breakpoint in the NoFoundServlet class.
5. run curl http://localhost:8080/demo-app-1/fdsfasdfdsa
6. Go to debug-view, try to evaluate variables,will get error: Cannot evaluate because of java.lang.IllegalStateException: Cannot evaluate, please specify projectName in launch.json..

In step 2, if I use mvnDebug tomcat7:run to launch, there will be no problem. I have compared the vimspector debug log, and find nothing different between jetty:run and tomcat7:run.

Expected behavior The variable evaluation function as expected.

It does not work with jetty:run

It seems like a env problem, I have tested in another computer, it is all ok. It could be a problem of maven 3.8.1.
