o run dex in process, the Gradle daemon needs a larger heap.
It currently has 1024 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to at least 1536 MB.
To do this set org.gradle.jvmargs=-Xmx1536M in the project gradle.properties.

实际上整个开发工具的最大内存是3246M了，为毛有这样的问题呢？

看来这玩意分为2种，一种是相对开发工具一种是相对gradle，而这里的问题是编译里面的gradle,所以在当前项目新建​​gradle.properties​​ 添加如下内容

org.gradle.jvmargs=-Xmx1536M

不过很郁闷的是这样搞只是针对当前项目的，如果是mac可以这样做

vim ~/.gradle/gradle.properties

window则是自己找用户名文件夹了，换汤不换药。
