This is the procedure used by eggrobin to build and deploy the JSPs from his Windows machines. Some of the commands must be run in PowerShell, others in the wsl bash.

WSL:

pushd UnicodeJsps
./update-bidic-ucd.sh
popd
wget https://github.com/unicode-org/last-resort-font/releases/latest/download/LastResort-Regular.ttf
mv ./LastResort-Regular.ttf ./UnicodeJsps/src/main/webapp/

Powershell:

mvn -B package -am -pl UnicodeJsps -DskipTests=true
$CLDR_REF = $(mvn help:evaluate "-Dexpression=cldr.version" -q -DforceStdout).Split("-")[2]
if (-not (Test-Path cldr)) {
  git clone https://github.com/unicode-org/cldr.git "--reference=..\cldr"
}
Push-Location cldr
git fetch
git reset --hard $CLDR_REF
Pop-Location

WSL:

mkdir -p UnicodeJsps/target && tar -cpz --exclude=.git -f UnicodeJsps/target/cldr-unicodetools.tgz ./cldr/ ./unicodetools/

Powershell:

rm .\Generated\* -recurse -force;
mvn compile exec:java '-Dexec.mainClass="org.unicode.jsp.RebuildPropertyCache"' -am -pl unicodetools   "-DUNICODETOOLS_GEN_DIR=Generated"  "-DUNICODETOOLS_REPO_DIR=." "-DCLDR_DIR=..\cldr\"

WSL:

tar -cpz -f UnicodeJsps/target/generated.tgz ./Generated/
docker build -t us-central1-docker.pkg.dev/goog-unicode-dev/unicode-jsps/unicode-jsps:latest UnicodeJsps/

Powershell:

docker push us-central1-docker.pkg.dev/goog-unicode-dev/unicode-jsps/unicode-jsps:latest
