Building Java/Scala in Eclipse 2020-06 with bndtools fails

I am trying to migrate a large PDE based OSGi code base to bndtools but I am stuck with getting a project that contains Scala code working. The projects that only contain Java code work build perfectly. I am using the Scala-IDE and added Scala nature to the project. Upon building this project I get the error / stacktrace attached below.

This is the .project file:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
    <name>com.sendrato.traxyz.positioning</name>
    <comment></comment>
    <projects>
    </projects>
    <buildSpec>
        <buildCommand>
            <name>bndtools.core.bndbuilder</name>
            <arguments>
            </arguments>
        </buildCommand>
        <buildCommand>
            <name>org.scala-ide.sdt.core.scalabuilder</name>
            <arguments>
            </arguments>
        </buildCommand>
    </buildSpec>
    <natures>
        <nature>org.eclipse.jdt.core.javanature</nature>
        <nature>bndtools.core.bndnature</nature>
        <nature>org.scala-ide.sdt.core.scalanature</nature>
    </natures>
</projectDescription>

Does anyone has similar issues and knows how to solve this?
