java.lang.NoSuchMethodError 当 运行 使用 Junit 5 测试时
java.lang.NoSuchMethodError when run test with Junit 5
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>
下一个是堆栈跟踪:
Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.getDefaultClassLoader()Ljava/lang/ClassLoader;

知道哪里出了问题吗?
除了依赖,你的pom.xml
里有没有配置JUnit5插件?它应该看起来像这样(取自 the docs):
...
<build>
<plugins>
...
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19</version>
<dependencies>
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-surefire-provider</artifactId>

我看到您正在使用仅支持特定版本的 jUnit5 的 IntelliJ。
Junit5 - running tests in IntelliJ
尝试例如
<version>5.0.0-M4</version>
