For some reason the last release lacked signatures. Would be nice to get in place for 3.4.4:

https://plugins.gradle.org/m2/com/google/cloud/tools/jib/com.google.cloud.tools.jib.gradle.plugin/3.4.3/

Also no signatures here:

https://plugins.gradle.org/m2/com/google/cloud/tools/jib-gradle-plugin/3.4.3/

This forces users of gradle dependency verification to whitelist the checksum rather than relying on signature verification.
