Error in using SBT ASEMBLY COMMAND

[hmhm1190]

I am trying to to generate binary file using SBT ASSEMBLY, but the generated jar file is corrupted.
Upon checking, every other command is giving this error

$ sbt "runMain org.allenai.pdffigures2.FigureExtractorVisualizationCli /home/husainmalwat/src_pdf"
