Answer 1

I had the below jar files in the path inside the plugin folder:
./var/lib/jenkins/plugins/build-pipeline-plugin/WEB-INF/lib/httpcore-4.2.1.jar
./var/lib/jenkins/plugins/git-client/WEB-INF/lib/httpcore-4.3.2.jar
./var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/httpcore-4.2.4.jar

After, I removed the below file, it worked for me
/var/lib/jenkins/plugins/build-pipeline-plugin/WEB-INF/lib/httpcore-4.2.1.jar
