CVE-2019-10753

In all versions prior to version 3.9.6 for eclipse-wtp, all versions prior
to version 9.4.4 for eclipse-cdt, and all versions prior to version 3.0.1
for eclipse-groovy, Spotless was resolving dependencies over an insecure
channel (http). If the build occurred over an insecure connection, a
malicious user could have perform a Man-in-the-Middle attack during the
build and alter the build artifacts that were produced. In case that any of
these artifacts were compromised, any developers using these could be
altered. Note: In order to validate that this artifact was not
compromised, the maintainer would need to confirm that none of the
artifacts published to the registry were not altered with. Until this
happens, we can not guarantee that this artifact was not compromised even
though the probability that this happened is low.
