Improve GRADLE build Performance

[shisheng-1]

Parallel builds. This project contains multiple modules. Parallel builds can improve the build speed by executing tasks in parallel. We can enable this feature by setting org.gradle.parallel=true.

File system watching. Since Gradle 6.5, File system watching was introduced which can help to avoid unnecessary I/O. This feature is the default since 7.0. For an older version, we can enable this feature by setting org.gradle.vfs.watch=true.

Configuration on demand. Configuration on demand tells Gradle to configure modules that only are relevant to the requested tasks instead of configuring all of them. We can enable this feature by setting org.gradle.configureondemand=true.

gradle caching. Shared caches can reduce the number of tasks you need to execute by reusing outputs already generated elsewhere. This can significantly decrease build times. We can enable this feature by setting org.gradle.caching=true.
