* LUCENE-9382: update gradle to 6.4.1. Requires minor changes around log call validation by restructuring the code around switches to a series of ifs. Piggybacking: apply log validation to :solr modules. Add inputs declaration so that task is not re-run on unmodified files.
ASF Release Policy states that we cannot have binary JAR files checked
in to our source releases, a few other projects have solved this by
modifying their generated gradlew scripts to download a copy of the
wrapper jar.
We now have a version and checksum file in ./gradle/wrapper directory
used for verifying the wrapper jar, and will take advantage of single
source java execution to verify and download.
The gradle wrapper jar will continue to be available in the git
repository, but will be excluded from src tarball generation. This
should not change workflows for any users, since we expect the gradlew
script to get the jar when it is missing.
