我们需要在Jenkins文件中调用java类函数。从groovy类调用java函数时工作。但当java函数从Jenkins文件调用时，同样会失败。
java类：src/main/java

package package_java;

import java.io.Serializable;

public class JavaGroovy implements Serializable {

public void mul (){
System.out.println("Java function is called");

}}
groovy类-变量。还尝试将其放在src/main/java下-两者都没有帮助

import package_java.*

    class executeJava implements Serializable{
    JavaGroovy javaGroovy = new JavaGroovy(); 

    def setJava(){
       javaGroovy.mul()
       }}

Jenkins档案：

# !groovy

@Library(["com.dtcc.dal","com.dtcc.diaci", "com.dtcc.ddptest@currentBranch", "com.**.common"]) _

import groovy.json.JsonSlurperClassic
pipeline {
    agent { node { label "$NodeName" } }
    stages {
    stage('TC: Test calling java function') {

            steps {
                script {

                   println "git checkout repo "
                   ddpCommitHash = gitCheckout(ddp_repo, ddp_revision, "iac")

                   def utils = load "${env.WORKSPACE}/iac/vars/executeJava.groovy"
                   utils.setJava()
                  println "java function is called"

                }
            }
        }
    }
}

错误

NOTE- Java class, groovy class are available in the workspace .

Please help . I guess i am missing something.

Thanks
