Intellij不运行Junit5测试

这是与Maven surefire plugin does not detect Junit5 tests相关的问题，我已阅读userguide。

我的pom.xml中有以下内容，当我运行maven安装时，测试运行。

然而，当我使用Intellij IDEA 2017.1.5运行时，单元测试会抛出以下异常

Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.launcher.Launcher.execute(Lorg/junit/platform/launcher/LauncherDiscoveryRequest;)V
at com.intellij.junit5.JUnit5IdeaTestRunner.startRunnerWithArgs(JUnit5IdeaTestRunner.java:61)

at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242)
at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70)

不幸的是，升级Intellij本身需要花费更长的时间才能在企业环境中实现，所以有没有办法让它在Intellij 2017.1.5中运行以便运行测试？

仅供参考我试图运行的测试不是复古测试，它是使用org.junit.jupiter.api.Test注释的简单Junit5测试

更新surefire

我隐约记得，过去2-3年中surefire有了重大更新。尝试更新您的maven-surefire-plugin，当前版本为3.0.0-M3。

新的junit-jupiter工件

请注意，从JUnit 5.4.0开始，我们可以指定junit-jupiter的新的且非常方便的单个Maven工件，这反过来将为您的项目提供8个库。

简化您的POM

您可以大大简化POM。这是一个来自maven-archetype-quickstart 1.4版原型的POM示例，尽管我已更新了2019年1月的所有版本号。

        </pluginManagement>
    </build>
</project>

提示：如果要在与测试相关的类之外使用JUnit断言，请在常规应用类中删除<scope>test</scope>元素。

示例类测试

package work.basil.example;

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertTrue;

/**
 * Unit test for simple App.
 */
public class AppTest 
{
    /**
     * Rigorous Test :-)
     */
    @Test
    public void shouldAnswerWithTrue()
    {
        assertTrue( true );
    }
}

我在Gradle 5.0中使用了以下依赖项：

testCompile('org.junit.jupiter:junit-jupiter-api:5.4.0')
testCompile('org.junit.jupiter:junit-jupiter-params:5.4.0')
testCompile('org.junit.platform:junit-platform-commons:1.4.0')
testRuntime('org.junit.jupiter:junit-jupiter-engine:5.4.0')
