I want to use different JDK versions for different stages in Jenkins declarative pipeline. In the first stage I am using Java 8. In the second stage i am using Java 6. How to select multiple JDK version in declarative pipeline in Jenkins? pipeline { agent any tools { jdk 'jdk_1.8.0_151' jdk 'jdk_1.6.0_45' } stages { stage('java 8') { steps { sh 'java -version' sh 'javac -version' } } stage('java 6') { steps { sh 'java -version' sh 'javac -version' } } } } you can add a tools section for each stage. pipeline { agent any stages { stage ("first") { tools { jdk "jdk-1.8.101" } steps { sh 'java
