基于:源代码

我不明白为什么参数Source.fromIterator是Function0[Iterator[T]]而不是Iterator[T].

这有一个实际的原因吗？我们可以def fromIterator(iterator: => Iterator[T])改为签名吗？(为了避免这样做Source.fromIterator( () => myIterator))

我正在尝试安装和使用Grails的Quartz插件.我的grails版本是2.3.7

我添加compile ":quartz:1.0.1"到我的Build.config中; 并下载quartz-2.2.1.jar和quartz-jobs-2.2.1.jar; 然后将这些.jar文件添加到我的/lib文件夹中.

当我尝试时grails run-app,出现以下错误:

Compile error during compilation with javac.
