无法强制 gradlew 根据条件构建失败

Question

我已将

StandardOutputListener

添加到我的

gatlingRun

文件下的

build.gradle

任务中。预期是，如果作业开始因标准输出中失败的请求而出现错误

OK=0

，则任务

gatlingRun

和 gradle 构建应该会失败。

build.gradle

：

plugins {
    id 'java'
    id 'io.gatling.gradle' version '3.9.0.2'
}

group 'org.example'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

gatling {
    simulations =  {
        exclude "**/simulations/CallBackSimulation.java"
    }
}

dependencies {
    gatling 'org.json:json:20230227'
    // ...
}

test {
    useJUnitPlatform()
}

// Problematic method
tasks.named("gatlingRun") {
    def outputListener = new StandardOutputListener() {
        void onOutput(CharSequence output) {
            if(output.contains("OK=0")) {
                throw new BuildCancelledException('An error occurred with Gatling requests')
            }
        }
    }
    logging.addStandardOutputListener(outputListener)
}

当我运行gradle命令时，构建仍然成功。虽然异常被准确抛出，但仍然打印 Build Sucessful 消息，并且

echo $?

返回 0，而不是 1。

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

See https://docs.gradle.org/7.4/userguide/command_line_interface.html#sec:command_line_warnings

我做错了什么？我还尝试过

GradleException

和

StopExecutionException

。不工作。有人可以帮忙吗？

这不是加特林测试失败的正确方法。您必须在模拟中定义断言。
