在IDEA Terminal終端運行$ mvn clean package -Dmaven.test.skip=true進行清除編譯文件時報錯。

解決思路

1、 檢查pom.xml文件中關于maven編譯插件的版本信息

<plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-compiler-plugin</artifactId>
         <configuration>
           <source>1.7</source>
           <target>1.7</target>
           <encoding>UTF-8</encoding>
           <compilerArguments>
             <extdirs>${project.basedir}/src/main/webapp/WEB-INF/lib</extdirs>
           </compilerArguments>
         </configuration>
</plugin>

發現版本信息需要完善，完善后如下：

<plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
         <!-- <version>3.6.2</version>-->
          <configuration>
            <source>1.8</source>
            <target>1.8</target>
           <fork>true</fork>
          <!--以下javac的路徑為電腦實際jdk1.8的安裝路徑-->
            <executable>E:\software\jdk1.8\bin\javac</executable>
            <encoding>UTF-8</encoding>
            <compilerArguments>
              <extdirs>${project.basedir}/src/main/webapp/WEB-INF/lib</extdirs>
            </compilerArguments>
          </configuration>
        </plugin>

2、檢查IDEA系統配置jdk版本

3、再次執行命令$ mvn clean package -Dmaven.test.skip=true
