使用 Jython 在 Robot Framework 中使用自定义 Java keywords/library

Question

我正在尝试将我自己的 Java 库导入 RFW 以使用关键字。导入硒工作正常。我已将 java class 导出到 .jar。我尝试过的事情：

1) 将 .jar 和 .robot 文件放在同一文件夹中：

λ jython -m robot testcase1.robot

将 MyTestLib.jar 粘贴到 C:\Program Files\jython2.7.2\Lib\site-packages 和运行:

λ jython -m robot testcase1.robot

jython -Dpython.path=C:\Users\User\eclipse-workspace\testrobot\src\test\robotframework\acceptance\ -m robot testcase1.robot

将我的 CLASSPATH 环境变量设置为 C:\Users\User\eclipse-workspace\testrobot\src\test\robotframework\acceptance 和运行

λ jython -m robot testcase1.robot

每次我得到同样的错误：

[ ERROR ] Error in file 'C:\Users\User\eclipse-workspace\testrobot\src\test\robotframework\acceptance\testcase1.robot' on line 5: Importing library 'MyTestLib.jar' failed: NoClassDefFoundError: com/company/testautomation/testrobot/MyTestLib (wrong name: MyTestLib)

我做错了什么？

这是我的 java class:


public class MyTestLib {

    
    public static final String ROBOT_LIBRARY_SCOPE = "GLOBAL";

    
    public void hello(String name){
        System.out.println("Hello " + name + ".\n");
    }

    public void Nothing(){
    }

}

这是我的测试套件：

Library    MyTestLib.jar

我认为我正确安装了所有要求：

Answer 1

尝试在 CLASSPATH envvar 中添加“MyTestLib.jar”的完整路径，例如：

export CLASSPATH=\path\to\MyTestLib.jar

使用Windows等价物，当然

Answer 2

我使用了 .class 文件而不是 .jar，这似乎解决了问题，但不知道为什么 .jar 不起作用。

使用 Jython 在 Robot Framework 中使用自定义 Java keywords/library
