Android Espresso - java.lang.OutOfMemoryError : GC overhead limit exceeded

Question

当我在我的项目中包含 espresso 快照 jar 时，我的 gradle 编译挂起然后退出并显示以下消息:

:Project:dexFlavorEnterpriseDebug FAILED

根据我的研究，这听起来像是一个依赖性问题。你会如何建议我去解决这个问题？

我尝试增加堆空间 (-Xmx2048)，但构建运行了很长一段时间(几分钟)，同时我的计算机变得越来越热但没有完成。没有这个 jar，编译永远不会超过一分钟。

Answer 1

我认为有一种单独的方法可以提高 dexing 操作的堆限制。将此添加到您的 build.gradle 文件中的 android 闭包中:

dexOptions {
    incremental true
    javaMaxHeapSize "4g"
}
