Working Maven project reports multiple errors in VSCode and will not build

I have a simple working Java Maven project. This project builds (assuming you have Java and Maven setup) - with:

mvn clean install

And the jar file runs as expected.

However, when I open it in VSCode (I have the Java Extension pack installed) - I see 105 "Problems" reported in the pom.xml:

• 4x "Failed to read artifact descriptor for ..."
• The rest "Missing artifact ..."

This appears to prevent most of the VSCode Java tools from working - I can't build and debug. Intellisense seems to be sketchy/intermittent. And so on.

Environment

• Operating System: Windows 10
• JDK version: OpenJDK 11.0.5.10
• Visual Studio Code version: 1.41.1
• Java extension version: 0.55.0

Steps To Reproduce

1. Extract the attached zip file to a folder
2. Open the folder in VSCode and inspect the Problems tab
3. Attempt to build the project

vsc-java-test.zip

To prove Maven works

1. Extract the attached zip file to a folder
2. Open a bash or cmd window, cd to the folder and run mvn clean install
3. Copy the generated thularest-1.0.jar file from <folder>/target to <folder>/bin
4. cd to /bin and run ./rest-start.sh
5. Crowse to http://localhost:8080/api/hello

Reproduce the report with the attached vsc-java-test.zip: open the Maven project in VSCode, inspect the Problems tab, and compare it with mvn clean install in a shell. Trace the Java extension's project import and dependency resolution from the reported diagnostics; done means the valid project no longer shows the missing-artifact errors and Java build/debug tooling works.
