我正在尝试使用JUnit5。
首先，我向maven项目添加了依赖项：

<dependencies>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>5.3.0</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.platform</groupId>
        <artifactId>junit-platform-runner</artifactId>
        <version>1.3.0</version>
        <scope>test</scope>
    </dependency>
</dependencies>

然后，我创建了一个测试：

package com.example.multicurrency;

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

class JunitTests {
    @Test
    void testAssertTrue() {
        assertTrue(false);
    }
}

然后，我运行测试，得到的结果如下：

org.junit.platform.launcher.core.DefaultLauncher handleThrowable
warning: TestEngine with ID 'junit-vintage' failed to discover tests
java.lang.NoClassDefFoundError: org/junit/platform/engine/support/filter/ExclusionReasonConsumingFilter
Caused by: java.lang.ClassNotFoundException: org.junit.platform.engine.support.filter.ExclusionReasonConsumingFilter

org.opentest4j.AssertionFailedError: 
Expected :<true> 
Actual   :<false>

结果如我所料。但是警告令我困惑。警告是什么意思？
