This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.7/userguide/gradle_daemon.html 

如何從Java文件中運行相同的測試：例如

的src/main/JAVA /鈣/ TestRunner.java

import cucumber.api.CucumberOptions; 
import cucumber.api.junit.Cucumber; 
import org.junit.runner.RunWith; 
import org.junit.runner.notification.Failure; 

@RunWith(Cucumber.class) 
@CucumberOptions(format = {"pretty"}, monochrome=true) 

public class TestRunner { 

       public static void main(String[] args) { 
            System.out.println("dummy main java"); 
// I want to run the tests from within the jar file 

              } 
} 

這樣，當我做Java的罐子建立/發行/黃瓜JVM的Groovy的example.jar

我應該得到相同的結果時，我使用的gradle運行通過命令行測試

我用下面的Java類：

import org.junit.*; 
import org.junit.runner.JUnitCore; 
import org.junit.runner.Result; 
import org.junit.runner.notification.Failure; 
import cucumber.api.CucumberOptions; 
import cucumber.api.junit.Cucumber; 
import org.junit.runner.RunWith; 
import java.util.ArrayList; 
import java.util.List; 
import org.junit.runner.notification.Failure; 

@RunWith(Cucumber.class) 
@CucumberOptions(format = {"pretty"}, monochrome=true) 

public class TestRunner { 

     public static void main(String[] args) { 
      System.out.println("dummy main java"); 
     JUnitCore.main("cucumberTest.TestRunner"); 
    } 
} 

但有例外：

initializationError(org.junit.runner.JUnitCommandLineParseResult) 
java.lang.IllegalArgumentException: Could not find class [cucumberTest.TestRunner] 
     at org.junit.runner.JUnitCommandLineParseResult.parseParameters(JUnitCommandLineParseResult.java:102) 
     at org.junit.runner.JUnitCommandLineParseResult.parseArgs(JUnitCommandLineParseResult.java:50) 
     at org.junit.runner.JUnitCommandLineParseResult.parse(JUnitCommandLineParseResult.java:44) 
     at org.junit.runner.JUnitCore.runMain(JUnitCore.java:72) 
     at org.junit.runner.JUnitCore.main(JUnitCore.java:36) 
     at TestRunner.main(TestRunner.java:19) 
Caused by: java.lang.ClassNotFoundException: cucumberTest.TestRunner 

這讓我想到，JUnitCore.main（）需要一個類名作爲參數

的一種方法是使用command line runner。 Java類Runtime允許您從Java內執行命令行。關鍵是cucumber.api.cli.Main。

喜歡的東西this：

task cucumber() { 
dependsOn assemble, compileTestJava 
doLast { 
    javaexec { 
     main = "cucumber.api.cli.Main" 
     classpath = configurations.cucumberRuntime + sourceSets.main.output + sourceSets.test.output 
     args = ['--plugin', 'pretty', '--glue', 'gradle.cucumber', 'src/test/resources'] 
     } 
    } 
}
