Error occurred during initialization of VM； Could not reserve enough space for 1572864KB object heap

下边是新建项目之后，提示的完整错误信息

Error:Failed to complete Gradle execution.Cause:Unable to start the daemon process.This problem might be caused by incorrect configuration of the daemon.For example, an unrecognized jvm option is used.Please refer to the user guide chapter on the daemon at https://docs.gradle.org/2.14.1/userguide/gradle_daemon.htmlPlease read the following process output to find out more:-----------------------Error occurred during initialization of VMCould not reserve enough space for 1572864KB object heap

Error:Failed to complete Gradle execution ，告诉我们无法启动守护进程。那么到底是什么原因导致的呢？ 在最下边的两行告诉了我们原因

Error occurred during initialization of VM；

Could not reserve enough space for 1572864KB object heap

1572864KB = 1536M

可以看出，在初始化虚拟机时，没有足够的堆内存。

解决方法：

在项目的工作空间下，修改 gradle.properties 文件，修改之前的内容：（可以看出错误提示1572864KB的原因了）

# Project-wide Gradle settings.# IDE (e.g. Android Studio) users:# Gradle settings configured through the IDE *will override*# any settings specified in this file.# For more details on how to configure your build environment visit# http://www.gradle.org/docs/current/userguide/build_environment.html# Specifies the JVM arguments used for the daemon process.# The setting is particularly useful for tweaking memory settings.org.gradle.jvmargs=-Xmx1536m# When configured, Gradle will run in incubating parallel mode.# This option should only be used with decoupled projects. More details, visit# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects# org.gradle.parallel=true

把 -Xmx1536m 改成 -Xmx512m ，保存之后，再 Rebuild 就可以了。

PS：

-xmx是设置虚拟机的内存大小, 如果程序非常占内存, 需要用这个参数设置一下。
-Xmx512m JVM最大允许分配的堆内存，按需分配。

-cp就是classpath, 加载类的路径
