I’ve recently forked the repo, cloned it, and ran mvn clean package inside the VSCode terminal, and I am getting this error. I saw a post here with an identical problem but it did not seem resolved (?) I am new to this so pardon.
If it matters my Java version is 1.8.0_401 and Maven version is 3.9.6.
