# LongRunningOperation

interface LongRunningOperation

Offers ways to communicate both ways with a Gradle operation, be it building a model or running tasks.

Enables tracking progress via listeners that will receive events from the Gradle operation.

Allows providing standard output streams that will receive output if the Gradle operation writes to standard streams.

Allows providing standard input that can be consumed by the gradle operation (useful for interactive builds).

Enables configuring the build run / model request with options like the Java home or JVM arguments. Those settings might not be supported by the target Gradle version. Refer to Javadoc for those methods to understand what kind of exception throw and when is it thrown.
