Hello, I found a little typo in https://poi.apache.org/components/poi-jvm-languages.html#Scala+example
Update: // Add the POI core and OOXML support dependencies into your build.sbt libraryDependencies ++= Seq( "org.apache.poi" % "poi" % "5.0.0-SNAPSHOT", "org.apache.poi" % "poi-ooxml" % "5.0.0-SNAPSHOT", "org.apache.poi" % "poi-ooxml-lite" % "5.0.0-SNAPSHOT" ) a % was missing in the last line Regards Bernhard Eichinger
