I use download-maven-plugin:wget in order to download some legacy dependencies unavailable on Maven Central or any other public Maven repository. Some are binary distributions, some source packages. Some are on Apache archive servers, some are download links for GitHub releases, downloading source code as ZIP files in order to package them into source code archives for binaries found elsewhere.
This has worked well for a long time (at least two months or so), but starting today I noticed builds failing, e.g. this one Search for “:wget” (without quotes) in the build log. There should be 8 occurrences. You willl also see “Ignoring download failure” at the end of each occurrence.
Is this a temporary network problem or did GitHub somehow start to block HTTP downloads? But actually, that would not make sense, because many dependency downloads in the same build work perfectly.
