使用带有 Kotlin 的 JSR223 绑定参数失败

Question

为 JMeter 添加 Kotlin JSR223 支持并使用 Kotlin 语言执行脚本

它忽略了JMeter绑定参数，作为String类型Parameters，试过了：

println(Parameters)

收到未解决的错误：

我尝试使用$：

println($Parameters)

歧义错误

使用 [bindings][1] as 也失败了

 println(bindings["ctx"])

类似的错误：

 javax.script.ScriptException: Error: Unresolved reference: bindings

我也尝试添加importAllBindings，但结果相同

importAllBindings(true)

JMeter 的bindings 代码：

 Bindings bindings = engine.createBindings();
 bindings.put("Parameters", scriptParameters); 
 ...
 CompiledScript compiledScript = compiledScriptsCache.get(newCacheKey);
 ...  
 compiledScript.eval(bindings)

如果不使用编译脚本，错误类似

在 JSR223 中使用 Scala 时也有类似的 issue

在使用 Scala 引擎时不能使用绑定参数（在其他引擎中，如 beanshell、groovy、velocity 等）
