使用Junit 5运行测试时的java.lang.NoSuchMethodError

Question

我创建了一个简单的测试来尝试Junit 5:

import org.junit.jupiter.api.Test;
public class MyTest {

    @Test
    public void testJupiter() {
        System.out.println("test");
    }
}

这是我使用的依赖:

        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-api</artifactId>
            <version>5.0.0</version>
            <scope>test</scope>
        </dependency>

堆栈跟踪是下一个:

Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.getDefaultClassLoader()Ljava/lang/ClassLoader;
at org.junit.platform.launcher.core.ServiceLoaderTestEngineRegistry.loadTestEngines(ServiceLoaderTestEngineRegistry.java:30)

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

出了什么问题？

Answer 1

我看到你使用IntelliJ,它只支持特定版本的jUnit5.

Junit5 - 在IntelliJ中运行测试

试试例如

<version>5.0.0-M4</version>
