Org.jruby.jcodings/jcodings==1.0.5 bad sha1 on Maven Central

Howdy, all –

I’m trying to use the split-out (as opposed to -complete) build of JRuby
from Maven.

At present, this fails:

[antlib:org.apache.ivy.ant:install] :: problems summary ::
[antlib:org.apache.ivy.ant:install] :::: WARNINGS

Looking at the published files, the .pom.sha1 file legitimately does not
match the checksum of the .pom.

I see a similar issue for org.jruby.extras.bytelist/bytelist==1.0.8:

What’s the history here?
