Maven Surefire 测试失败：不支持 class 文件主要版本 61

Question

I am trying to create a project in IntelliJ using Maven, but when running mvn install or mvn test in order to run the simple JUnit tests I wrote, it fails with the following error:

Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test (default-test) on project Idlearn: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test failed: Unsupported class file major version 61 -> [Help 1]

My pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project>
    <modelVersion>4.0.0</modelVersion>

    <groupId>mimuw</groupId>
    <artifactId>Idlearn</artifactId>
    <version>1</version>
    <name>Idlearn</name>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <!-- for platform independent encoding-->
        <junit.version>5.8.2</junit.version> <!-- the latest JUnit version -->
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter</artifactId>
            <version>${junit.version}</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.2</version>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>17</source>
                    <target>17</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

I feel like I have tried every possible solution on the web, but to no avail.

The problem originally was that my tests wouldn't run. The command mvn test would output that it was running SomeClassTest however not run any actual tests that it contained (all created just like in many tutorials I found on-line). It seems like I was missing maven-surefire and here I am now.

This is what worked for me using Java 17.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.ow2.asm</groupId>
            <artifactId>asm</artifactId>
            <version>9.1</version>
        </dependency>
    </dependencies>
</plugin>

And when upgrading to Java 18 this morning, I had to upgrade to asm v9.3 as well.

I hope it helps.
