Question

我已经制作了一个自定义的grunt任务，它将过滤后的文件嵌入到Visual Studio C＃项目文件（*.csproj）中。

任务（vsembed）是我使用grunt开发的自定义构建系统的一部分。

问题是一个奇怪的问题，但是......

TL; DR

如果我执行特定目标的任务 - 成功。如果我一次运行所有目标 - 退出没有错误。

长版。

如果我运行指定目标的任务（因此它运行一次），它就会成功完成，如下所示：

如果我为整个小组运行任务，它有时完成3个，有时4个目标，有时在完成第4个中间退出。这是最新运行的输出，它停止在上面特定目标示例中显示的相同任务，这是第4个任务。

“强制退出”我的意思是，正如您在上面看到的那样，它以File: [no files]结束，这是在详细模式下运行时的本机grunt功能。始终后跟Options，如上面这三个目标输出所示。

感觉好像是在达到超时或内存限制后发生的。

如果我删除了一些基于XML的任务，任务将完成（但是，失去了所有目的），所以我认为问题可能在于libxmljs。是什么让我只假设，是最后一个输出 - 即使grunt原生输出被切断。

正在运行Windows 7 x64，node v0.10.29，npm 1.4.14，grunt-cli v0.1.13，grunt v0.4.5。

我真的没有线索......

什么可能导致单个目标执行的问题，但是多个顺序“无声地失败”？

Answer 1

非常有趣的是，开始调试这一点，我偶然发现node-memwatch。

添加一些HeapDiff检查使我的任务运行，因此，它看起来与内存/ GC有关。

删除HeapDiff项检查，使用global.gc();添加手动GC清除并使用--expose-gc运行 grunt 解决了问题。

可悲的是，但现在从一个简单的grunt vsembed我必须在本地（而不是-g）安装 grunt 和 grunt-cli ，然后运行它node --expose-gc node_modules\grunt-cli\bin\grunt vsembed。

好吧，无论如何，它已经解决了。

Grunt在一项任务中间“停止”

TL; DR

长版。
