groovy - 调用 eachParallel() 时的 Groovy (GPars) 和 MissingMethodException

Question

当我在控制台（groovy 2.1.3）中运行以下代码时：

strings =  [ "butter", "bread", "dragon", "table" ]
strings.eachParallel{println "$it0"}

我得到：

groovy.lang.MissingMethodException: No signature of method: java.util.ArrayList.eachParallel() is applicable for argument types: (ConsoleScript40$_run_closure1) values: [ConsoleScript40$_run_closure1@a826f5]

谁能告诉我我做错了什么？

我认为您缺少设置。尝试

@Grab(group='org.codehaus.gpars', module='gpars', version='1.0.0')
import groovyx.gpars.GParsPool

GParsPool.withPool {
    def strings =  [ "butter", "bread", "dragon", "table" ]
    strings.eachParallel { println it }
}
