Arvados

This is done. It was complicated by the fact that we switched from using the Gradle Docker image to the Gradle in Debian, which is sufficient for testing but apparently doesn't have enough to upload. I'll make a separate ticket about cleaning that up. In the meantime, for posterity, here is our current code for build-java-sdk.

#!/usr/bin/env bash
set -euo pipefail
case "$UPLOAD_PACKAGES" in
  1 | true ) UPLOAD_PACKAGES=uploadArchives ;;
  * ) UPLOAD_PACKAGES= ;;
esac

cp -t "$WORKSPACE/contrib/java-sdk-v2" "$gradle_properties" "$secring" 
docker run --interactive --rm \
  --mount "type=bind,src=$WORKSPACE/contrib/java-sdk-v2,dst=/mnt" \
  --user "$(id -u)" \
  --workdir /mnt \
  gradle:6 \
  gradle -Pversion="$ARVADOS_BUILDING_VERSION" --info --stacktrace \
  clean test jar install $UPLOAD_PACKAGES

if [[ -n "$UPLOAD_PACKAGES" ]]; then
  auth="Authorization: Bearer $(awk '
  (/^ossrhUsername=/) { uname=substr($0, 15); }
  (/^ossrhPassword=/) { pword=substr($0, 15); }
  END { printf("%s:%s", uname, pword); }
' "$gradle_properties" | base64)" 
  curl --data "" --header "$auth" --fail --location --silent --show-error \
