Doesn't support Maven project with source folder at the root

[yyoncho]

Project: https://github.com/vspinu/IBjts

My guess is that it the issue is caused by the fact that the project overrides the source location to ..

    <build>
        <sourceDirectory>.</sourceDirectory>
        <directory>build</directory>

Oddly the project is imported fine when I first import another project and then add IBjts via workspace/didChangeWorkspaceFolders . But after I restart the workspace it does work again.

Indeed this project is bending the Maven conventions to a point which is not supported by m2e, and it's unlikely it will ever be. You'll definitely get better luck moving the code to src/main/java and then simplifying your pom.xml to read:
