Question

我正在开发STS中的java maven项目（基于Eclipse Juno 3.8.2），我收到以下错误：

java.lang.ClassFormatError：类文件org / eclipse / jdt / internal / junit4 / runner / JUnit4TestReference中不兼容的魔术值0

我认为它与混合Java版本有关，但我无法解决它，可能我错过了一些东西。

完整的堆栈跟踪是：

我发现，只有在我尝试运行JUnit测试时才会出现问题，我的项目运行正常。我试图检查运行配置，似乎没关系。我也检查了项目方面，一切似乎都没问题......

Answer 1

尽管在命令行上有1.7.0_17，但我认为你的Eclipse运行在旧版本的java上。要确定正在运行的Java Eclipse版本，请参阅：

Find out what JVM Eclipse is running on

然后更改正在运行的Eclipse的java版本，参见：

http://wiki.eclipse.org/Eclipse.ini#Specifying_the_JVM

希望有所帮助。

Answer 2

看起来，这是STS的一些普遍问题（基于Eclipse Juno 3.8.2）。

我尝试了最简单的测试，但它也没有工作：

的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>net.betlista</groupId>
    <artifactId>tests-sts</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>3.2.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.2.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>3.2.2.RELEASE</version>
        </dependency>
    </dependencies>

</project>

测试类

package net.betlista.tests.sts.junit;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration( classes = { JavaConfig.class } )
public class CalculatorTest {

    @Autowired
    Calculator calculator;

    @Test
    public void addTest() {
        final int a = 10, b = 20;
        Assert.assertEquals( a + b, this.calculator.add( a, b ) );
    }

}

配置类

package net.betlista.tests.sts.junit;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JavaConfig {

    @Bean
    public Calculator getCalculator() {
        return new Calculator();
    }

}

服务类

package net.betlista.tests.sts.junit;

import org.springframework.stereotype.Service;

@Service
public class Calculator {

    int add( final int a, final int b ) {
        return a + b;
    }

}

我在STS（3.8.2）中遇到同样的错误，而在STS（4.2.2）中一切正常。

Answer 3

这里只需清理并重建项目即可解决

在我的情况下，当我改变所提到的类的超类时发生了这个错误;

我的stacktrace中提到的类是我项目中的一个类，而不是像你这样的特定库

org/eclipse/jdt/internal/junit4/runner/JUnit4TestReference

希望能帮到你

Answer 4

我收到了此错误消息，但没有任何效果。我的问题可能与我将新类从开发转移到生产的方式有关。我在 Dev 上创建了新类并将其复制到 Production，而不是 .war 文件，最后 tomcat 文件夹上的类所有者是“root”，而不是“tomcat”，“chown”到 tomcat 解决了这个问题。
