一、mvn clean package打包报错

错误信息比较冗长，着重看这两点：

不建议去检索的方向：

二、问题总结

Execution default of goal org.springframework.boot:spring-boot-maven-plugin:3.0.0-M1:repackage failed: Unable to load the mojo 'repackage' in the plugin 'org.springframework.boot:spring-boot-maven-plugin:3.0.0-M1' 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

翻译下就是:

我有尝试以下几种办法：皆不得~~

1、升级jdk8到jdk11

/Library/Java/JavaVirtualMachines/jdk1.8.0_201.jdk/Contents/Home/bin/java
修改为
 /Library/Java/JavaVirtualMachines/jdk-11.0.2.jdk/Contents/Home/bin/java -Dmaven.multiModuleProjectDirectory=/Users/xxx/Documents/code/xxl-job -Dmaven.home=/Users/xxx/Documents/apache-maven-3.3.9 -Dclassworlds.conf=/Users/xxx/Documents/apache-maven-3.3.9/bin/m2.conf "-javaagent:/Applications/IntelliJ IDEA.app/Contents/lib/idea_rt.jar=52826:/Applications/IntelliJ IDEA.app/Contents/bin" -Dfile.encoding=UTF-8 -classpath /Users/xxx/Documents/apache-maven-3.3.9/boot/plexus-classworlds-2.5.2.jar org.codehaus.classworlds.Launcher -Didea.version=2018.2.3 -s /Users/xxx/Documents/apache-maven-3.3.9/conf/settings.xml package

2、maven settings.xml中增加aliyun mirror。

  <mirrors>
  
    <mirror>
      <id>nexus-aliyun</id>
      <mirrorOf>central</mirrorOf>
      <name>Nexus aliyun</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>

  </mirrors>

3、修改下载realse包的策略，仍然是从maven下载包的角度去试图修正。

<releases><enabled>true</enabled></releases>
修改为
<releases><enabled>true</enabled><updatePolicy>always</updatePolicy></releases>

4、在pom.xml手动增加远程仓库的配置

5、问题还是回到Maven插件spring-boot-maven-plugin这，先看下项目中的pom.xml内容：

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <finalName>${project.artifactId}</finalName>
<mainClass>com.xxl.job.admin.XxlJobAdminApplication</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

出现问题的原因正是我们没有指定它的version，每次maven都会获取spring-boot-maven-plugin插件最新的版本，结果最新的版本3.0.0-M1已经不支持goal这个API了。

修改后的Pom.xml见下：<version>2.2.6.RELEASE</version>具体的版本号可以灵活变动，否则它的版本号是3.0.0-M1。

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.2.6.RELEASE</version>
                <configuration>
                    <finalName>${project.artifactId}</finalName>
                    <mainClass>com.xxl.job.admin.XxlJobAdminApplication</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

三、总结

maven坐标是包括groupId、artifactId和version三者的，很多时候没有指定version，是因为有父依赖，所以一定要明确自己的版本号是多少。不过像本次的打包出错，是新版本不兼容旧版的api接口，多少有点坑，特此记录，希望能帮助到你~
