【问题描述】：

我在使用Annotation Library 为 Java 挑选自定义关键字时遇到问题。我面临的问题是使用 jybot 执行时出现以下错误：

导入的库 'org.robotframework.javalib.library.ClassPathLibrary' 不包含关键字

导入的库 'org.robotframework.javalib.library.AnnotationLibrary' 不包含关键字

找不到名为“创建空堆栈”的关键字 使用的 Jybot 命令：jybot example.txt。下面是实际的测试用例和为此测试用例调用的库：

*** Settings ***
Library    org.robotframework.javalib.library.ClassPathLibrary     org/robotframework/example/keyword/**.class
Library    org.robotframework.javalib.library.AnnotationLibrary    org/robotframework/example/keyword/**.class


*** Test Cases ***

Stack Example
      Create an Empty Stack
      Add an Element Java
      Add an Element C++
      Remove last Element
      The last Element should be

以下是为合并关键字而编写的库：

package org.robotframework.example.keyword;

import org.robotframework.javalib.annotation.RobotKeyword;
import org.robotframework.javalib.annotation.RobotKeywords;
import org.robotframework.javalib.library.AnnotationLibrary;

/**
 * 
 */

    /**
     * 
     */
    @RobotKeywords

    public class StackKeyword extends AnnotationLibrary 
        /** This means the same instance of this class is used throughout
         *  the lifecycle of a Robot Framework test execution.
         */
        public static final String ROBOT_LIBRARY_SCOPE = "GLOBAL";

        public StackKeyword() 
            super("org/robotframework/example/keyword/**/*.class");
        
        //</editor-fold>
        /** The Functionality to be tested */
        private java.util.Stack<String> testStack;

        /**
         * Keyword-method to create an empty stack.
         */
        @RobotKeyword
        public void createAnEmptyStack() 
            testStack = new java.util.Stack<String>();
        


        /**
         * Keyword-method to add an element to the stack.
         * @param element The element
         */
        @RobotKeyword
        public void addAnElement(String element) 
            testStack.push(element);
        

        /**
         * Keyword-method to remove the last element from the stack.
         */
        @RobotKeyword
        public void removeLastElement() 
            testStack.pop();
        

        /**
         * Keyword-method to search for an element position.
         * @param element The element
         * @param pos The expected position
         */
        @RobotKeyword
        public void elementShouldBeAtPosition(String element, int pos)
                throws Exception 
            if (testStack.search(element) != pos) 
                throw new Exception("Wrong position: " + testStack.search(element));
            
        

        /**
         * Keyword-method to check the last element in the stack.
         * @param result Expected resulting element
         */
        @RobotKeyword
        public void theLastElementShouldBe(String result) throws Exception 
            String element = testStack.pop();
            if (!result.equals(element)) 
                throw new Exception("Wrong element: " + element);
            
        



    

【参考方案1】：

添加一个类扩展AnnotationLibrary并实现默认构造函数。

public class DemoLibrary extends AnnotationLibrary 

    public DemoLibrary () 
        super("org/robotframework/example/**/*.class");
    

把你的关键字类放在包org.robotframework.example.keywords下

仅放在example.txt文件中；

Library           org.robotframework.example.DemoLibrary

确保您在该路径上有 DemoLibrary。
