Gradle refuse to start process command 'cmd'

Question

I'm encountering issue with a custom gradle task. Seems like gradle refuse to start a command line process.

Here is the custom task:

task generateAllure(type: Exec) {
    workingDir "$projectDir/allure/bin"
    if (System.getProperty('os.name').toLowerCase(Locale.ROOT).contains('windows')) {
        commandLine 'cmd', '/c', 'allure.bat', 'generate', '-c', '../../integration/build/allure-results'
    } else {
        commandLine 'bash', '-c', 'allure', 'generate', '-c',"$projectDir/integration/build/allure-results"
    }
}

tasks.withType(Test)*.finalizedBy generateAllure

With the appropriate dependency:

compile group: 'ru.yandex.qatools.allure', name: 'allure-commandline', version: '1.4.18'

After using gradle clean test execution fails on:

2: Task failed with an exception.
-----------
* What went wrong:
Execution failed for task ':generateAllure'.
> A problem occurred starting process 'command 'cmd''

Any thoughts about that? Thanks!

UPD: This is the stacktrace i'm getting after performing gradle -S clean test:

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':generateAllure'.

Try running `gradle -S clean test` and post the full stacktrace in your question. I would also suggest creating a reproducible github repo — Boaz, Jul 11 '18 at 06:11
@Boaz Hello there! May i ask your attention again? I've added the full stacktrace after performing the gradle -S clean test. If you have any thoughts please share them with me. Thanks. — lilkunien, Jul 25 '18 at 15:21

Now with the stacktrace the problem is pretty much clear. In the task you defined

task generateAllure(type: Exec) {
    workingDir "$projectDir/allure/bin"
    if (System.getProperty('os.name').toLowerCase(Locale.ROOT).contains('windows')) {
        commandLine 'cmd', '/c', 'allure.bat', 'generate', '-c', '../../integration/build/allure-results'
    } else {
        commandLine 'bash', '-c', 'allure', 'generate', '-c',"$projectDir/integration/build/allure-results"
    }
}

tasks.withType(Test)*.finalizedBy generateAllure

You've set the working directory to "$projectDir/allure/bin" this value get interpolated into "D:\Git\rozetka-test-automation\allure\bin" which apparently doesn't exist on your system

Keep in mind that "doesn't exist" might also mean "doesn't exist yet", it depends on what you're doing in the rest of your build.

Under the assumption the allure\bin is not created by the build - something is wrong with your path.
