The reasoning is simple: improve build speed by reusing computations from previous builds

Running Daemon Status

To get a list of running Gradle Daemons and their statuses use the --status command.

Sample output:

   PID VERSION                 STATUS
  28411 3.0                     IDLE
  34247 3.0                     BUSY
Enter fullscreen mode Exit fullscreen mode

Disabling the Daemon

You can disable the long-lived Gradle daemon via the

--no-daemon command-line option
Enter fullscreen mode Exit fullscreen mode

, or by adding

 org.gradle.daemon=false
Enter fullscreen mode Exit fullscreen mode

to your gradle.properties file

Stopping an existing Daemon

If you want to explicitly stop running Daemon processes for any reason, just use the

command gradle --stop.
Enter fullscreen mode Exit fullscreen mode

How do I disable the Gradle Daemon?

Via environment variables:

add the flag -Dorg.gradle.daemon=false 
Enter fullscreen mode Exit fullscreen mode

to the GRADLE_OPTS environment variable

Via properties file:

add org.gradle.daemon=false 
Enter fullscreen mode Exit fullscreen mode

to the «GRADLE_USER_HOME»/gradle.properties file

On Windows, this command will disable the Daemon for the current user:

(if not exist "%USERPROFILE%/.gradle" mkdir "%USERPROFILE%/.gradle") && (echo. >> "%USERPROFILE%/.gradle/gradle.properties" && echo org.gradle.daemon=false >> "%USERPROFILE%/.gradle/gradle.properties")
Enter fullscreen mode Exit fullscreen mode

On UNIX-like operating systems, the following Bash shell command will disable the Daemon for the current user:

mkdir -p ~/.gradle && echo "org.gradle.daemon=false" >> ~/.gradle/gradle.properties
Enter fullscreen mode Exit fullscreen mode

Once the Daemon is disabled for a build environment in this way, a Gradle Daemon will not be started unless explicitly requested using the --daemon option.

Why is there more than one Daemon process on my machine?

If the requested build environment does not specify a maximum heap size, the Daemon will use up to 512MB of heap. It will use the JVM’s default minimum heap size. 512MB is more than enough for most builds.

How can I stop a Daemon?

Daemon process before this, you can either kill the process via your operating system or run the

 gradle --stop
Enter fullscreen mode Exit fullscreen mode

Watching the file system

To force Gradle to keep information about unsupported file systems between builds, the feature must be enabled explicitly by one of these methods:

Run with --watch-fs on the command line
Enter fullscreen mode Exit fullscreen mode

This forces watching the file system for this build only.

Put

org.gradle.vfs.watch=true 
Enter fullscreen mode Exit fullscreen mode

in your gradle.properties
This forces watching the file system for all builds, unless explicitly disabled with --no-watch-fs.
