Answer 1

In your pipeline, you have to declare the jdk.
You have to configure tool jdk in global tools administration.
Example:
pipeline {
tools {
jdk 'openjdk-1.8'
maven 'Maven_3_5_2'
}
stages {
stage('Build') {
steps {
echo 'Building..'
sh "mvn clean install"
}
}
}
}
You can also modify JAVA_HOME localy to the node.
node {
jdk = tool name: 'JDK17'
env.JAVA_HOME = "${jdk}"
echo "jdk installation path is: ${jdk}"
// next 2 are equivalents
sh "${jdk}/bin/java -version"
// note that simple quote strings are not evaluated by Groovy
// substitution is done by shell script using environment
sh '$JAVA_HOME/bin/java -version'
}
