Running Selenium webdriver-manager from Gradle

Question

I am trying to start Selenium from Gradle in order to run Protractor tests.

Here is my Gradle script:

//main task to run protractor tests
task uiTests << {
    println "Starting protractor tests"
}

//start Selenium server
task startSelenium << {
    println "Starting Selenium..."
    ant.exec(executable: '/bin/bash', spawn: true) {
        arg(value:'webdriver-manager')
        arg(value:'start')
    }
}

//run protractor
task runProtractor(type: Exec) {
    commandLine 'protractor', 'bignibou-client/protractor.conf.js'
}

//start selenium, then run protractor
uiTests.dependsOn([startSelenium, runProtractor])

However, the output seems to indicate that the Selenium process has not being started:

 :runProtractor

Can anyone please provide informed tips and guidance?

By referring the webdriver-manager script directly as shown below sorted the issue:

//main task to run protractor tests
task uiTests << {
    println "Starting protractor tests"
}

//start Selenium server
task startSelenium << {
    println "Starting Selenium..."
    ant.exec(executable: 'webdriver-manager', spawn: true) {//CHANGED!!
        arg(value: 'start')
    }
}

//run protractor
task runProtractor(type: Exec) {
    commandLine 'protractor', 'bignibou-client/protractor.conf.js'
}

//start selenium, then run protractor
uiTests.dependsOn([startSelenium, runProtractor])
