A shell script to get all projects spring-boot version

Just wrote a quick shell script to get all projects spring-boot version

#!/bin/bash

# A quick shell script to check the spring-boot version
# only work for gradlw project!!
# read repo-name from services.csv
# cat services.csv 
# demp app,camel-spring-demo


set -e

servicelist=$(pwd)/services.csv # desc,repo-name
output=$(pwd)/spring-ver.csv
repo_base="https://github.com/softarts/"  # my repo root path
# "https://$username:$pass@github.com/softarts/"  # it may need username/pass

# pull all code under ./tmp/
mkdir -p tmp
cd ./tmp/

while read -r line || [[ -n "$line" ]];
do
  echo $line
  # skip line start with '#' 
  [[ $line =~ ^#.* ]] && continue
  if printf '%s\n' "$line" | grep -q -e ','; then
    varname=$(printf '%s\n' "$line" | sed -e 's/,.*//')  # replace first part with empty
    varvalue=$(printf '%s\n' "$line" | sed -e 's/^[^,]*,//')  # replace second part with empty
    varvalue="$(echo -e "${varvalue}" | tr -d '[:space:]')"
    
    repo="$repo_base$varvalue.git"
    echo "$varname:$varvalue:$repo"

    if [ -d $varvalue ];then
      echo "Directory $varvalue exists."
      cd $varvaluegit pull
      cd ..
    else
      git clone --depth=1 $repo
    fi

    springver="skip"
    if [ -f "$varvalue/gradlew" ];then
      echo "running gradlew"
      springver=$($varvalue/gradlew -x test -b $varvalue/build.gradle -q dependencyInsight --dependency spring-boot</dev/null|grep "org.springframework.boot:spring-boot:"|head -n 1 |awk -F":" '{ print $3}')
    else
      echo "non-spring"
      springver="non-spring-boot"
    fi

    echo "$varname:$varvalue:$springver"
    echo "$varname:$varvalue:$springver">>$output
  fi
done < $servicelist

and this is my services.csv file

cat services.csv 
demp app,camel-spring-demo

Output is:

cat spring-ver.csv # it is spring-boot 3.0.2
demp app:camel-spring-demo:3.0.2 (selected by rule)

The key is

# without `</dev/null` it will break the whil loop 
gradlew -q dependencyInsight --dependency spring-boot</dev/null

Happy Coding!
