Karate调用多参数Java方法出现语法错误（Cucumber转Karate POC）

错误原因 #

你遇到的org.graalvm.polyglot.PolyglotException: SyntaxError: Unnamed:1:76 Expected an operand but found eof错误，是因为错误使用了call关键字调用Java静态方法。Karate中call主要用于调用feature文件或JS函数，直接用它带多参数调用Java方法会触发语法解析失败，单参数场景只是巧合通过解析。

正确调用方式 #

方式1：先获取Java类对象再调用 #

Scenario: get all users and then get the first user by id
    Given def param1 = ""
    And def param2 = ''
    And def param3 = ''
    And def param4 = ''
    And def param5 = ''

    * def KafkaSteps = Java.type('com.automation.tesco.stepdefs.KafkaSteps')
    * KafkaSteps.createKafkaStockChangeEvent(param1, param2, param3, param4, param5)

方式2：直接通过全限定类名调用静态方法 #

Scenario: get all users and then get the first user by id
    Given def param1 = ""
    And def param2 = ''
    And def param3 = ''
    And def param4 = ''
    And def param5 = ''

    * com.automation.tesco.stepdefs.KafkaSteps.createKafkaStockChangeEvent(param1, param2, param3, param4, param5)

验证说明 #

两种方式都能正确识别多参数的Java静态方法签名，替换原有的call行后即可正常执行，不会再触发语法错误。
