- ## Method Details

  - ### withArguments

    T withArguments(String... arguments)
    Specify the command line build arguments. Useful mostly for running tasks via `BuildLauncher`.

    Be aware that not all of the Gradle command line options are supported! Only the build arguments that configure the build execution are supported. They are modelled in the Gradle API via `StartParameter`. Examples of supported build arguments: '--info', '-p'. The command line instructions that are actually separate commands (like '-?' and '-v') are not supported. Some other instructions like '--daemon' are also not supported - the tooling API always runs with the daemon.

    If an unknown or unsupported command line option is specified, `UnsupportedBuildArgumentException` will be thrown at the time the operation is executed via `BuildLauncher.run()` or `ModelBuilder.get()`.

    For the list of all Gradle command line options please refer to the User Manual or take a look at the output of the 'gradle -?' command. Majority of arguments modeled by `StartParameter` are supported.

    The arguments can potentially override some other settings you have configured. For example, the project directory or Gradle user home directory that are configured in the `GradleConnector`. Also, the task names configured by `BuildLauncher.forTasks(String...)` can be overridden if you happen to specify other tasks via the build arguments.

    See the example in the docs for `BuildLauncher` If not configured, null, or an empty array is passed, then the reasonable default will be used.

    Requires Gradle 1.0 or later.

    Specified by:
      `withArguments` in interface `LongRunningOperation`

    Specifies the Java VM arguments to use for this operation.

    `BuildEnvironment` model contains information such as Java or Gradle environment. If you want to get hold of this information you can ask tooling API to build this model.

    If not configured, null, or an empty array is passed, then the reasonable default will be used.

    The jvm argument set by this method is independent of arguments set by {`addJvmArguments`} methods. The daemon JVM arguments list will always have the arguments from the {`setJvmArguments`} at the beginning of the list, and then have the {`addJvmArguments`} configuration appended.

    Specified by:
      `setJvmArguments` in interface `LongRunningOperation`
    Parameters:
      `jvmArguments` - to use for the Gradle process
    Returns:
      this

  - ### setJvmArguments

    T setJvmArguments(Iterable<String> jvmArguments)
    Specifies the Java VM arguments to use for this operation.

    `BuildEnvironment` model contains information such as Java or Gradle environment. If you want to get hold of this information you can ask tooling API to build this model.

    If not configured, null, or an empty list is passed, then the reasonable default will be used.

    The jvm argument set by this method is independent of arguments set by {`addJvmArguments`} methods. The daemon JVM arguments list will always have the arguments from the {`setJvmArguments`} at the beginning of the list, and then have the {`addJvmArguments`} configuration appended.

    Specified by:
      `setJvmArguments` in interface `LongRunningOperation`
    Parameters:
      `jvmArguments` - to use for the Gradle process
    Returns:
      this
    Since:
      2.6

  - ### addJvmArguments

    T addJvmArguments(String... jvmArguments)
    Appends Java VM arguments to the existing list.

    The jvm argument set by this method is independent of arguments set by {`setJvmArguments`} methods. The daemon JVM arguments list will always have the arguments from the {`setJvmArguments`} at the beginning of the list, and then have the {`addJvmArguments`} configuration appended.

    Specified by:
      `addJvmArguments` in interface `LongRunningOperation`
    Parameters:
      `jvmArguments` - the argument to use for the Gradle process
    Returns:
      this
    Since:
      5.0

  - ### withSystemProperties

    T withSystemProperties(Map<String,String> systemProperties)
    Sets system properties to pass to the build.

    By default, the Tooling API passes all system properties defined in the client to the build. If called, this method limits the system properties that are passed to the build, except for immutable system properties that need to match on both sides.

    System properties can be also defined in the build scripts (and in the gradle.properties file), or with a JVM argument. In case of an overlapping system property definition the precedence is as follows:

    - `withSystemProperties(...)` (highest)
    - `addJvmArguments(...)` and `setJvmArguments(...)`
    - build scripts

    Note: this method has "setter" behavior, so the last invocation will overwrite previously set values.

    Specified by:
      `withSystemProperties` in interface `LongRunningOperation`
    Parameters:
      `systemProperties` - the system properties add to the Gradle process. Passing `null` resets to the default behavior.
    Returns:
      this
    Since:
      7.6

  - ### addJvmArguments

    T addJvmArguments(Iterable<String> jvmArguments)
    Appends Java VM arguments to the existing list.

    The jvm argument set by this method is independent of arguments set by {`setJvmArguments`} methods. The daemon JVM arguments list will always have the arguments from the {`setJvmArguments`} at the beginning of the list, and then have the {`addJvmArguments`} configuration appended.

    Specified by:
      `addJvmArguments` in interface `LongRunningOperation`
    Parameters:
      `jvmArguments` - the argument to use for the Gradle process
    Returns:
      this
    Since:
      5.0

  - ### setEnvironmentVariables

    T setEnvironmentVariables(Map<String,String> envVariables)
    Specifies the environment variables to use for this operation.

    `BuildEnvironment` model contains information such as Java or Gradle environment. If you want to get hold of this information you can ask tooling API to build this model.

    If not configured or null is passed, then the reasonable default will be used.

    Specified by:
      `setEnvironmentVariables` in interface `LongRunningOperation`
    Parameters:
      `envVariables` - environment variables
    Returns:
      this
    Since:
      3.5

  - ### addProgressListener

    T addProgressListener(ProgressListener listener)
    Adds a progress listener which will receive progress events as the operation runs.

    This method is intended to be replaced by `LongRunningOperation.addProgressListener(org.gradle.tooling.events.ProgressListener)`. The new progress listener type provides much richer information and much better handling of parallel operations that run during the build, such as tasks that run in parallel. You should prefer using the new listener interface where possible. Note, however, that the new interface is supported only for Gradle 2.5.

    Specified by:
      `addProgressListener` in interface `LongRunningOperation`
    Parameters:
      `listener` - The listener
    Returns:
      this
    Since:
      1.0-milestone-3

  - ### addProgressListener

    T addProgressListener(ProgressListener listener)
    Adds a progress listener which will receive progress events of all types as the operation runs.

    This method is intended to replace `LongRunningOperation.addProgressListener(ProgressListener)`. You should prefer using the new progress listener method where possible, as the new interface provides much richer information and much better handling of parallel operations that run during the build.

    Supported by Gradle 2.5 or later. Gradle 2.4 supports `OperationType.TEST` operations only. Ignored for older versions.
