Gradle - How to add some delay pause hang in Gradle

Question

Im looking for a way to insert a pause of few seconds between the calls of two gradle tasks.

I can use

}

something like which can do Linux/Unix

sleep 45

Any ideas?

Answer 1

First, I'd try to find a better solution than waiting for so long every time. Anyway, to delay the first task for 45 seconds, you can do:

firstTask.doLast {
    sleep(45 * 1000)
}

A good way to familiarize yourself with Groovy's core APIs is to study the Groovy JDK (also known as GDK). It's also a handy reference.

Or: firstTask { // some stuff here; doLast { sleep(45 * 1000) } } – Elbertina

If you want to run integration tests in Tomcat, then simply use the Gradle Tomcat Plugin like this:

ext {
    tomcatStopPort = 8081
    tomcatStopKey = 'stopKey'
}

task integrationTomcatRun(type: org.gradle.api.plugins.tomcat.TomcatRun) {
    stopPort = tomcatStopPort
    stopKey = tomcatStopKey
    daemon = true
}

task integrationTomcatStop(type: org.gradle.api.plugins.tomcat.TomcatStop) {
    stopPort = tomcatStopPort
    stopKey = tomcatStopKey
}

task integrationTest(type: Test) {
    include '**/*IntegrationTest.*'
    dependsOn integrationTomcatRun
    finalizedBy integrationTomcatStop
}

test {
    exclude '**/*IntegrationTest.*'
}

Hi Vidya, Can you provide a way to add a delay. firstTask deploys a .war in Tomcat (which is already running, so basically tomcat just takes 30-45 seconds to recycle to pick the new .war provided by the new build), i want to wait 45 seconds after that happens and before I call gradle integrationTest task (i.e. my secondTask). – Fugitive

Actually the one you mentioned I had that code already but all I needed was how to insert delay. Due to lot of customizations we have, I think we can't use Gradle's Tomcat Plugin but thanks for your inputs. Thanks Vidya. – Fugitive
