在win上打包可能会遇到这样的错误

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 33280 MB (based on the dexOptions.javaMaxHeapSize = 32g).
To do this set org.gradle.jvmargs=-Xmx33280M in the project gradle.properties.
For more information see https://docs.gradle/current/userguide/build_environment.html

FAILURE: Build failed with an exception.

* What went wrong:
Gradle build daemon has been stopped: JVM garbage collector thrashing and after running out of JVM memory

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

解决方案：

在路径Copied it to C:\Users\***\.gradle下面创建一个gradle.properties文件，在其中写入

org.gradle.parallel=true
org.gradle.daemon=true
org.gradle.jvmargs=-Xmx12800M
org.gradle.configureondemand=true

这个错误的大致原因就是打大型apk包时会出现jvm空间不够的情况，小包情况下不会出现。
