如何限制DEX内存使用情况 [英] How to limit DEX memory usage

问题描述

我想设置DEX任务可以在基于gradle这个功能的Andr​​oid项目中使用的最大内存，但无法找到任何选项来做到这一点。

I am trying to set the maximum memory that DEX task can use in a gradle-based Android project, but can't find any option to do that.

我的动机做，这是因为随着 DEX 有时需要我的电脑启动交换，并成为某些分钟（所以我宁愿看到任务完全没有反应这么多内存失败，然后释放一些更多的资源和重试）

My motivation to do this is because as dex sometimes takes so much memory that my computer starts swapping and becomes completely unresponsive for some minutes (so I would rather see the task fail and then free some more resources and retry)

在我的 gradle.properties 我 org.gradle.jvmargs = - Xmx300m这限制了内存使用的摇篮本身，而是摇篮启动时DX它总是使用 -Xmx1024 。

In my gradle.properties I have org.gradle.jvmargs="-Xmx300m" which limits the memory used by Gradle itself, but when Gradle starts dx it always uses -Xmx1024.

那么，怎样才能让我限制摇篮DX所使用的内存？

So how can I make Gradle limit the memory used by dx?

推荐答案

在您的build.gradle脚本，设置dexOptions.javaMaxHeapSize配置，以任何你需要的值：

In your build.gradle script, set the dexOptions.javaMaxHeapSize configuration to whatever value you need:

android {
//snip
//add this into your existing 'android' block
    dexOptions {
        javaMaxHeapSize "4g"
    }
//snip
}
