AOP is failing while build sbt assembly - scala

Question

I am trying to build sbt code. I am using sbt assembly but it is breaking at Aop. Used following MergeStragegy for Aop
Following is the error log

Last week the same changes where working. But somehow it is throwing this error. What could be the reason?
sbt version -> 1.3.10
I have created a new MergeStrategy for aop.xml files (part of the Kamon dependencies).

If replacing http with https does not work, it might be worth trying disabling DTD validation as follows:
import java.io.FileInputStream
import org.xml.sax.InputSource
val parser = {
val factory = javax.xml.parsers.SAXParserFactory.newInstance()
factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false)
factory.newSAXParser()
}
val xmls: Seq[Elem] = files.map(f => XML.loadXML(new InputSource(new FileInputStream(f)), parser))
