maven 打包报错 this version of the Java Runtime only recognizes class file versions up to 55.0

 

报错信息：

org/springframework/boot/maven/RepackageMojo has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

 

原因： 

通过对应表可知，这个文件是由java 17版本编译的，而现在系统中只能识别java 8以下的版本，java版本不一致导致打包失败，需要在出错的模块的打包插件中设置一个版本就好了

java对应表

49 = Java 5
50 = Java 6
51 = Java 7
52 = Java 8
53 = Java 9
54 = Java 10
55 = Java 11
56 = Java 12
57 = Java 13
58 = Java 14

解决：

repackage中使用对应版本号：

<build>
        <finalName>${project.artifactId}</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.7.5</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
