如何在 Jenkinsfile 中动态加载共享库并执行它们的同名全局变量方法？

Question

我想在我的 Jenkinsfiles 中顺序加载可变命名的共享库，并在每个共享库中运行一个同名的全局变量方法。
IE。作为伪代码，我想做的是：

for lib in in [foo, bar]:
  load shared library(lib)
  run the shared library's global variable method named 'func()'

我尝试按如下方式实现：

// Jenkinsfile
pipeline {
  agent any

    stages {
      stage('1') {
        steps {
          testLoadLib()
        }
      }
    }
}

void testLoadLib() {
  runGlobalVariableMethod('foo@dev')
  runGlobalVariableMethod('bar@dev')
}

void runGlobalVariableMethod(String libraryName) {
  def lib = library(libraryName)
  def d = [:]
  func.func(d)
}

// shared_lib_foo
// vars/func.groovy

def func(d) {
  println("foo func.groovy:func()")
}

// shared_lib_bar
// vars/func.groovy

def func(d) {
  println("bar func.groovy:func()")
}

共享库已配置为 Jenkins 全局管道库，如下所示：

在运行 Jenkins 管道时，来自

func.func()

共享库的

foo@dev

运行两次，而不是从

foo@dev

运行一次，然后是

bar@dev

下一个。
即：
实际输出（为简洁起见进行了编辑）：

foo func.groovy:func()
foo func.groovy:func()

期望的输出：

foo func.groovy:func()
bar func.groovy:func()

问题：在 Jenkinsfile 和 Jenkins 共享库之间，如何实现所需的行为？
期望的行为是：我想加载多个共享库，迭代，并运行每个全局变量方法（具有相同的名称）。
有人可能将其描述为插件架构：加载一个变量/可指定的共享库，并在其中运行预期的功能。

未经编辑的 Jenkins 管道输出（为了更好的上下文）显示它似乎正在检查正确的共享库——我看到对各自共享库的 git 存储库和提交 ID 的正确引用：
