-P, --project-prop Set project property for the build script (e.g. -Pmyprop=myvalue).
-p, --project-dir Specifies the start directory for Gradle. Defaults to current directory.
--parallel Build projects in parallel. Gradle will attempt to determine the optimal number of executor threads to use.

--rerun-tasks Ignore previously cached task results.
-S, --full-stacktrace Print out the full (very verbose) stacktrace for all exceptions.
-s, --stacktrace Print out the stacktrace for all exceptions.
--scan Creates a build scan. Gradle will emit a warning if the build scan plugin has not been applied. (https://gradle.com/build-scans)
--status Shows status of running and recently stopped Gradle Daemon(s).
--stop Stops the Gradle Daemon if it is running.
-t, --continuous Enables continuous build. Gradle does not exit and will re-execute tasks when task file inputs change.
--update-locks Perform a partial update of the dependency lock, letting passed in module notations change version. [incubating]
-v, --version Print version info.
-w, --warn Set log level to warn.
--warning-mode Specifies which mode of warnings to generate. Values are 'all', 'fail', 'summary'(default) or 'none'
--watch-fs Enables watching the file system for changes, allowing data about the file system to be re-used for the next build. [incubating]
--write-locks Persists dependency resolution for locked configurations, ignoring existing locking information if it exists [incubating]
-x, --exclude-task Specify a task to be excluded from execution.

SDKMAN! is a tool for managing parallel versions of multiple Software Development Kits on most Unix-based systems.
$ sdk install gradle 6.6.1
Homebrew is “the missing package manager for macOS”.
$ brew install gradle
Other package managers are available, but the version of Gradle distributed by them is not controlled by Gradle, Inc. Linux package managers may distribute a modified version of Gradle that is incompatible or incomplete when compared to the official version (available from SDKMAN! or below).
The current Gradle release is version 6.6.1, released on 25 Aug 2020. The distribution zip file comes in two flavors:
If in doubt, choose the binary-only version and browse docs and sources online.
Need to work with an older version? See the releases page.
Unzip the distribution zip file in the directory of your choosing, e.g.:
$ mkdir /opt/gradle
$ unzip -d /opt/gradle gradle-6.6.1-bin.zip
$ ls /opt/gradle/gradle-6.6.1
LICENSE NOTICE bin getting-started.html init.d lib media
Create a new directory C:\Gradle
with File Explorer.
Open a second File Explorer window and go to the directory where the Gradle distribution was downloaded. Double-click the ZIP archive to expose the content. Drag the content folder gradle-6.6.1
to your newly created C:\Gradle
folder.
Alternatively you can unpack the Gradle distribution ZIP into C:\Gradle
using an archiver tool of your choice.
Configure your PATH
environment variable to include the bin
directory of the unzipped distribution, e.g.:
$ export PATH=$PATH:/opt/gradle/gradle-6.6.1/bin
In File Explorer right-click on the This PC
(or Computer
) icon, then click Properties
-> Advanced System Settings
-> Environmental Variables
.
Under System Variables
select Path
, then click Edit
. Add an entry for C:\Gradle\gradle-6.6.1\bin
. Click OK to save.
Open a console (or a Windows command prompt) and run gradle -v
to run gradle and display the version, e.g.:
$ gradle -v
------------------------------------------------------------
Gradle 6.6.1
------------------------------------------------------------
If your existing Gradle-based build uses the Gradle Wrapper, you can easily upgrade by running the wrapper
task, specifying the desired Gradle version:
$ ./gradlew wrapper --gradle-version=6.6.1 --distribution-type=bin
Note that it is not necessary for Gradle to be installed to use the Gradle wrapper. The next invocation of gradlew
or gradlew.bat
will download and cache the specified version of Gradle.
$ ./gradlew tasks

You can find all releases and their checksums on the releases page.
Command-line completion scripts are available for bash and zsh. This provides completion for Gradle tasks and command-line options.
