这个问题是由于编译过程中的Java的内存开销太大超过了默认限制导致的，解决方法就是增大Java的内存限制。

具体操作为在项目的 gradle.properties 中修改内存限制 org.gradle.jvmargs 默认情况下，这个限制在 1536m 我们需要拉大到 4096m 。

修改后的内容如下：

# Project-wide Gradle settings.
# IDE (e.g. Android Studio) users:
# Gradle settings configured through the IDE *will override*
# any settings specified in this file.
# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
org.gradle.jvmargs=-Xmx4096m
# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
# org.gradle.parallel=true

如果这个文件不存在，则在工程文件 build.gradle , gradlew , local.properties 等相同的目录下新建 gradle.properties 这个文件即可。
