Welcome to Gradle 3.3.
To run a build, run gradlew<task>…
To see a list of available tasks, run gradlew tasks
To see a list of Command-line options, run gradlew–help
To see m ore detail about a task, run gradlew help --<task>

so can you guys help me out thanks

You have to run the batch script from the command line and give it a task to run, eg


gradlew.bat tasks

will print out all the tasks you can run.
