Question

我正在尝试使用jruby语言执行JSR223

如果我放置普通的String可以工作，但是我不能将JMeter预定义变量用作log

log.info("Hello from JRuby");

无法找到log：

我在jruby wiki on JSR个示例中发现前缀为@variableName的变量

engine.put（“ @ name”，“樱花”）;

但是对于@log，我得到了不同的错误（因为它为Nil / Null）

javax.script.ScriptException: org.jruby.embed.EvalFailedException: (NoMethodError) undefined method info'for nil：NilClass`

可以克服它还是无法在JMeter的JSR223中运行jruby？

JRuby实际上可以使用$前缀找到预定义的变量：

$log.info("Hello from JRuby");

JSR223中的JRuby语言无法找到JMeter预定义变量
