Console application with Java and gradle

Question

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.

Answer 1

Chances are, the problem lies in your java code. All the application plugin does is compile the java code, and run the main class that you specify. Can you post the code in your main class that you specified for the application plugin (mainClassName) ?

Answer 2

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:

run{
    standardInput = System.in
}

Answer 3

As stated above, add

run {
   standardInput = System.in
}

And run:

gradle console:run -q --console=plain

where:

• -q runs task in "quiet" mode (to avoid having > Building > :run)
• --console=plain drops execution status: <=-> 80% EXECUTING [TIME]

Answer 4

For build.gradle.kts:

tasks.getByName<JavaExec>("run") {
    standardInput = System.`in`
}
