현존하는 대부분 라이브러리는 Semantic versioning이라는 규칙을 암묵적으로 따라 가고 있습니다.
특히 주버전의 변화에 주의해야 합니다. 예를 들면 Spring Boot 2와 3은 JDK 최소 버전이 달라서 2에서는 낮은 버전을 사용할 수 없어요. (물론 라이브러리가 꼭 이를 따른다고 볼 수 없고, 버그가 있을 수 있기 때문에 부, 수버전도 주의해야 합니다.) 따라서 라이브러리 이름 뒤에 라이브러리의 버전별 사용 현황은 https://mvnrepository.com/ 에서 라이브러리 검색 후 확인하실 수 있습니다. |

# Gradle start up script for POSIX generated by Gradle. | ||
# | ||
# Important for running: | ||
# | ||
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is | ||
# noncompliant, but you have some other compliant shell such as ksh or | ||
# bash, then to run this script, type that shell name before the whole | ||
# command line, like: | ||
# | ||
# ksh Gradle | ||
# | ||
# Busybox and similar reduced shells will NOT work, because this script | ||
# requires all of these POSIX shell features: | ||
# * functions; | ||
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}», | ||
# «${var#prefix}», «${var%suffix}», and «$( cmd )»; | ||
# * compound commands having a testable exit status, especially «case»; | ||
# * various built-in commands including «command», «set», and «ulimit». | ||
# | ||
# Important for patching: | ||
# | ||
# (2) This script targets any POSIX shell, so it avoids extensions provided | ||
# by Bash, Ksh, etc; in particular arrays are avoided. | ||
# | ||
# The "traditional" practice of packing multiple parameters into a | ||
# space-separated string is a well documented source of bugs and security | ||
# problems, so this is (mostly) avoided, by progressively accumulating | ||
# options in "$@", and eventually passing that to Java. | ||
# | ||
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS, | ||
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly; | ||
# see the in-line comments for details. | ||
# | ||
# There are tweaks for specific operating systems such as AIX, CygWin, | ||
# Darwin, MinGW, and NonStop. | ||
# | ||
# (3) This script is generated from the Groovy template | ||
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt | ||
# within the Gradle project. | ||
# | ||
# You can find Gradle at https://github.com/gradle/gradle/. | ||

JDK 17, 스프링 부트 3, Gradle 8.8을 쓰시는 것으로 보이는데요.
이 세개는 버전에 따라 조금씩 사용할 수 있는 것들이 달라서요.
실무에서 최신이 아닌 여러 버전을 쓸 수 있으니 차이점을 어느 정도 숙지하시고 서로 호환되는 여러 조합을 경험해보시면 좋을 것 같습니다. (e.g. JDK 8, 11, 17, 21, Gradle 6, 7, 8, ...)
