Add retries for common issues such as connect timeout, etc.
This won't solve the problem of read-timeouts happening around the actual
transferTo, but it is an easy incremental improvement.
* Upgrade several build dependencies.
* Update error prone rules (those are off but they do trigger warnings/ errors)
* A few corrections I made before I turned off new warnings. Let's do nother issue to fix them.
Upgrade jflex.
Change doesn't alter the behavior of any of the analyzers (unicode
version or grammar refactorings), just the minimal to get new tooling
working.
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.
