Unable to load the mojo ‘repackage‘ in the plugin ‘org.springframework.boot:spring-boot-maven-plug_unable to load the mojo 'repackage' in the plugin

1.最近接手了一个老项目，由于重启服务器，需要启动服务，但是发现再次部署Jenkis报错，不能重新部署报错，报错信息如下：

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:3.0.5:repackage (default) on project XX-manager: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:3.0.5:repackage failed: Unable to load the mojo 'repackage' in the plugin 'org.springframework.boot:spring-boot-maven-plugin:3.0.5' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: 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 52.0

ps：不涉及到Jenkis，如果是本地编译报错，也是这样解决处理。

2.原因

由于spring-boot-maven-plugin没有指定版本，Jenkis部署的时候自动获取最新版本，而最新版本的不兼容，导致的该问题，以下代码是历史代码：

 
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <mainClass>com.XXXX.XXXX</mainClass>
                        <fork>true</fork>
                        <addResources>true</addResources>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackage</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>

3.解决办法

spring-boot-maven-plugin指定版本，查看了Jenkis的部署成功的日志，之前成功的获取的版本是“2.2.5.RELEASE”（可以根据需要尝试低版本的），将version设置为2.2.5.RELEASE就可以了。

Jenkis部署成功的日志：
[INFO] --- spring-boot-maven-plugin:2.2.5.RELEASE:repackage (default) @ XXXX ---
[INFO] Replacing main artifact with repackaged archive

修改的配置文件：
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                      <version>2.2.5.RELEASE</version>
                    <configuration>
                        <mainClass>com.XXXX.XXXX</mainClass>
                        <fork>true</fork>
                        <addResources>true</addResources>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackage</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
