调用eachParallel（）时的Groovy（GPars）和MissingMethodException

Question

当我在控制台中运行以下代码时（groovy 2.1.3）：

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

我明白了：

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

任何人都可以告诉我我做错了什么？

我认为你错过了设置。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 }
}
