Speed up Gradle development with Gradle daemon

It takes a few seconds to finish the process, even there was only one file need to recompile. Because before gradle do any real building job, it have to does some initial work like loading JVM, prepare execution environ ment, loading Groovy classes etc.

When you frequently change and rebuild, the delay is add up.

To resolve this problem, Gradle add a new feature "daemon". The daemon is just a Java application this runs in background thus cut the startup cost.

To start the daemon

Gradle--daemon Build

You can see the speedup when run with the daemon.

The To use the daemon you has to add--daemon option every time running the build.

To let Gradle add this option automatically set the environment variable gradle_opts as this

Set gradle_opts= "-dorg.gradle.daemon=true"

In my experience, this should always is set.

To make sure the daemon was running, if you be under Linux, check with this command

PS | grep gradle

In Windows, check the IT in Task Manager

It eat MB of my memory. If you finish the development, it better to stop the daemon and free the memory. Its simple

Gradle--stop
