如何从另一个图书馆调用图书馆？

Question

我正在尝试创建几个库并调用它们。我的目标是将第二个方法称为第一个方法。

例如，我创建了两个库library1和library2。

Library1代码

class LibraryScriptTest1 {
    def log
    def context
    def testRunner
    def library2

    def LibraryScriptTest1(log, context, testRunner) {
        this.log = log
        this.context = context
        this.testRunner = testRunner

        library = testRunner.testCase.testSuite.project.testSuites["LibraryTestSuiteTest"]
        module = library.testCases["LibraryTestCaseTest2"].testSteps["LibraryScriptTest2"]
        module.run(testRunner, context)
        this.library2 = context.library2
    }

    int add(int firstNumber, int secondNumber) {
        return firstNumber + secondNumber
    }

    int multiply(int firstNumber, int secondNumber) {
        return firstNumber * secondNumber
    }

    int divide(firstNumber, secondNumber) {
        return this.library2.divide(firstNumber, secondNumber)
    }
}

context.setProperty("library1", new LibraryScriptTest1(log, context, testRunner))

Library2代码：

class LibraryScriptTest2 {
    def log
    def context
    def testRunner

    def LibraryScriptTest2(log, context, testRunner) {
        this.log = log
        this.context = context
        this.testRunner = testRunner
    }

    int substract(int firstNumber, int secondNumber) {
        return firstNumber - secondNumber
    }

    int divide(int firstNumber, int secondNumber) {
        return firstNumber / secondNumber
    }
}

context.setProperty("library2", new LibraryScriptTest2(log, context, testRunner))

错误

但是我在library1中遇到此错误：

  

groovy.lang.MissingPropertyException：没有此类属性：的库   类：LibraryScriptTest1可能的解决方案：第2行的library2错误：   XX

对应的行是下一行：

context.setProperty("library1", new LibraryScriptTest1(log, context, testRunner))

任何人都可以帮助我理解和解决该问题吗？谢谢。
