multithreading - 找不到Gpars withExistingPool错误jsr166y.ForkJoinPool

我已经从'org.codehaus.gpars:gpars:1.0.0'更新为'org.codehaus.gpars:gpars:1.1.0'。我的代码在1.0.0中可以正常工作，但是在1.1.0版中，我找不到jsr166y.ForkJoinPool。

如何获得正确的ForkJoinPool？

我使用的代码是:

import groovyx.gpars.GParsPool
import jsr166y.ForkJoinPool

class Test {
   def pool = new ForkJoinPool()

   def executeAsync(args, closure = null) {
    if(!closure) {
        closure = args
        args = null
    }

    GParsPool.withExistingPool(pool) {
        closure.callAsync(args)
    }
   }
}

我必须导入java.util.concurrent.ForkJoinPool以获取ForkJoinPool类。但是在运行时，出现以下错误:

最佳答案

将您的BuildConfog.groovy更新为:

compile 'org.codehaus.gpars:gpars:1.1.0'
compile 'org.codehaus.jsr166-mirror:jsr166y:1.7.0'

这应该为您工作。
