🔧 GitHub 플러그인 설치

• github와 jenkins을 연동 하기위해 GitHubVersion 1.34.4 플러그인 설치함
  [의존성 파일들도 함께 설치된다.]

🔧 GitHub Global Tool Configuration

# yum install -y git

• git plugin을 설치했지만 jenkins VM에는 git이 없기 때문에 설치해준다.

📝 Maven

# cd /opt
# wget https://dlcdn.apache.org/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz
# tar -xvzf apache-maven-3.8.6-bin.tar.gz
# mv apache-maven-3.8.6 maven
# cd maven
# cd bin
