如何解决 Unity Editor 中使用 Gradle 打包出现 Heap Space 不足的错误
最近在自己的开发机上和公司内部用的打包的机器上都出现了通过 Unity Editor 提供的 Gradle 打包流程打包 APK 文件时提示 Java Heap Space Error 的问题。
输出的错误日志内容如下：

Running dex as a separate process. To 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 2560 MB (based on the dexOptions.javaMaxHeapSize = 2g). To do this set org.gradle.jvmargs=-Xmx2560M in the project gradle.properties.

那就按照它的提示把 gradle 的配置修改一下吧，由于我使用的开发机和公司的打包机器都是 macOS 系统，所以只需要在 ~/.gradle 目录下的 gradle.properties 文件（如果该目录下没有这个问题件，可以通过 touch gradle.properties 命令创建）中新增下面的这行配置即可：
