gradle命令失败，因为它无法启动守护进程

Question

我试图运行gradle命令。这一开始工作。但是它在一段时间后已经开始失败，因为它不能启动守护进程。我在Windows 7 Enterprise上使用Gradle 2.5和IBM jdk 1.6。

我已清理我的用户主目录中的.gradle目录并重新启动我的系统。

这工作正常我的朋友机器相同的版本。 请帮忙。

不能确定您的方案（约IBM JDK），但每当守护程序，或者在一般的任何其他方面完全工作的身材，突然停止工作对我来说，我要做两件事情。

1. gradle myTask --no-daemon运行为了不守护建设，以确保如果它确实是有守护的一个问题。

2. gradle --stop杀死任何现有的守护进程，然后再次尝试编译。

有谨慎的关于在gradle docs使用Windows守护进程一句话：

也可以通过运行动摇守护进程（和一般的建设环境）建立不释放资源正确。在使用Microsoft Windows时，这是一个特别棘手的问题，因为它对读取或写入后无法关闭文件的程序的宽容度较小。
