报错信息例如：

java.exe'' finished with non-zero exit value 1

java.exe'' finished with non-zero exit value 2

java.exe'' finished with non-zero exit value 3

困扰了三天的Android Studio编译报错终于解决了！ 感谢CSDN的serapme
三天尝试了各种不同的方案针对各个不同的方方面面，然而真相只有一个！ 
原问题情景：由于项目工程特别大，在编译一段后就会报下面这个错误：

<code class="hljs livecodeserver has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">Error:Execution failed <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">for</span> task <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">':dexAppDebug'</span>.

在stackOverFlow上找了很多办法尝试都行不通，于是只能自己琢磨着不断尝试，最后在任务管理器中观察到studio.exe和java.exe运行时占用内存量较大，又考虑 

电脑配置可能不够用，所以开始不断尝试修改占用内存相关的东西，并终于取得了进展。关键代码是build.gradle中的：

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">dexOptions {
javaMaxHeapSize <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"xx"</span>
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

xx为合理的内存大小。如果你也遇到了这种问题，不妨试试~

android {
// 写在这里
dexOptions { javaMaxHeapSize "4g" }
}
