  $ gradle projects

Running build on specific subproject::

  $ gradle :$SUB:clean

  $ gradle -p $SUB clean

Getting list of supported tasks

===============================

::

  $ gradle tasks

Getting list of supported tasks in each subproject::

  $ gradle tasks --all

Getting help on task::

  $ gradle -q help --task build

Similar but to each task::

  $ gradle model

Build sources

=============

::

  $ gradle compileJava

  $ gradle compileTestJava

Run main class

==============

::

  $ gradle run

Run tests

=========

::

  $ gradle test

To run tests with additional registered checks::

  $ gradle check

.. note::

   ``--rerun-tasks`` option *specifies that any task optimization is ignored*.

   In that way you may rerun tests even if there are no changed files::

     $ gradle test --rerun-tasks

Stopping server

===============

::

  $ gradle --stop

List project dependencies

=========================

List of project execution dependencies (it also download dependencies)::

  $ gradle dependencies

  $ gradle dependencies --configuration compile

  $ gradle dependencies -p $SUBPROJ

  $ gradle :$SUBPROJ:dependencies

  $ gradle :$SUBPROJ:dependencies --configuration testCompile

List of project plugin dependencies::

  $ gradle buildEnvironment

  $ gradle buildEnvironment -p $SUBPROJ

  $ gradle :$SUBPROJ:buildEnvironment

Paths to dependencies can be printed via task::

  task printDepPaths {

    doLast { configurations.runtime.each { println it } }

  }

All dependencies can be copied to single directory via task::

  task copyRuntimeLibs(type: Copy) {

    into "lib"

    from configurations.runtime

    // from configurations.testRuntime - configurations.runtime

  }

List project properties

=======================

::

  $ gradle properties

  $ gradle :$SUBPROJ:properties

  $ gradle properties -p $SUBPROJ

Dry tun

``-m`` option allow parsing build scripts without actually executing them::

  $ gradle -m clean compile
