Gradle 拒绝启动进程命令 'cmd'

Question

我遇到了自定义 gradle 任务的问题。似乎 gradle 拒绝启动命令行进程。

这是自定义任务：

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

具有适当的依赖性：

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

使用 gradle clean test 后执行失败：

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

有什么想法吗？谢谢！

更新：这是我在执行 gradle -S clean test:

后得到的堆栈跟踪

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

现在有了堆栈跟踪，问题就很清楚了。在你定义的任务中

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

您已将工作目录设置为 "$projectDir/allure/bin" 此值被插入到 "D:\Git\rozetka-test-automation\allure\bin" 中，这显然在您的系统中不存在

请记住，"doesn't exist" 也可能意味着 "doesn't exist yet"，这取决于您在构建的其余部分中所做的事情。

假设 allure\bin 不是由构建创建的 - 您的路径有问题。
