推荐答案
正如您所说的，您没有使用任何自定义的JVM args，请尝试一下.
As you said you are not using any custom JVM args, try it out.
在您的gradle.properties文件中，尝试内存设置的多个值.例如，尝试设置
In your gradle.properties file try several values for memory settings. For example try to set
org.gradle.jvmargs=-Xmx4096m
如评论部分所建议:
该设置对于调整内存设置特别有用.
The setting is particularly useful for tweaking memory settings.
org.gradle.jvmargs = -Xmx1536m
org.gradle.jvmargs=-Xmx1536m
我在项目中使用了R8，并且一切正常.
I've used R8 in my project and all worked fine.
