maven - java.lang.NoClassDefFoundError : org/junit/platform/commons/PreconditionViolationException when trying run junit5 test with maven

Question

当尝试使用命令 mvn test 运行测试时，我收到一个错误:

我在 IntelliJ 2008.1 下运行它，使用 maven 3.6.1 和版本 2.22.1 中的 surefire 插件

我在 pom 中有以下依赖项:

<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api -->
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.5.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.5.0</version>
    <scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-params -->
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-params</artifactId>
    <version>5.5.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-launcher</artifactId>
    <version>1.5.0</version>
    <scope>test</scope>
</dependency>

...

<plugins>
    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
    </plugin>
</plugins>

最近我无法运行任何测试用例，但现在经过一些配置尝试后，我收到此错误。

Answer 1

删除 junit-platform-launcher , junit-jupiter-engine和 junit-jupiter-api .

添加 junit-jupiter . ( junit-jupiter 是聚合器)

它对我有用。
