I am writing a console application with Java and gradle. I am using the application
plugin and have the required fields correctly configured in build.gradle
.
In my main class I have BufferedReader
linked with System.in
. Here's the problem: When I run gradle run
in project directory, the reader does not wait for my console input. BufferedReader#readLine
instead returns null
on the very first call. This behavior is not desirable for what am I doing.
What is the solution? Is there a separate console application plugin for gradle or do I need to tweak application
plugin somehow to suit my needs?
To run a Gradle command, open a command window on the project folder and enter the Gradle command. Gradle commands look like this: On Windows: gradlew <task1> <task2> … e.g. gradlew clean allTests.
Gradle provides a command line to execute build script. It can execute more than one task at a time. This chapter explains how to execute multiple tasks using different options.
Per default the system.in of your gradle build is not wired up with the system.in of the run (JavaExec) task. You can do the following:
// build.gradle (Groovy syntax) run { standardInput = System.in } // build.gradle.kts (Kotlin syntax) tasks.named<JavaExec>("run") { standardInput = System.`in` }
