On the page Apache POI - Download Release Artifacts (https://poi.apache.org/download.html) the archive seems to be corrupted. Download link points to: http://www.apache.org/dyn/closer.lua/poi/release/bin/poi-bin-3.14.tar.gz Its size of 19MB as indicated results in 119MB effective file size after download. Some tools, such as Beyond compare, say that it "does not appear to be a valid gzip archive" Downloading this release from older archives (http://archive.apache.org/dist/poi/release/bin/poi-bin-3.14.tar.gz) seems to be fine. Kind regards PS.: Component is irrelevant
Which is the exact mirror you downloaded from? The link you have given is to the "nearest local mirror" redirect script. Without knowing what mirror you were sent to, we can't help - there are hundreds of them around the world!
Did the checksums and signatures check out? http://poi.apache.org/download.html
