You have to include a newer version of commons-compress and shade it (there ar different plugins in Maven, Gradle, SBT). Alternatively, you can use the HadoopOffice library, which has native Flink support, to read/write Excel files (https://github.com/zuinnote/hadoopoffice/wiki) and it has an example on how to shade the dependency correctly (see https://github.com/ZuInnoTe/hadoopoffice/wiki/Using-Apache-Flink-to-read-write-Excel-documents)
