[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:3.0.0:check (validate) on project devops-brain: Failed during checkstyle configuration: Cannot set property 'cacheFile' to 'F:\Copote\Code\devops-brain\devops-brain\target/checkstyle-cachefile': InvocationTargetException: com/谷歌/common/io/Flushables: com.谷歌.common.io.Flushables -> [Help 1]

 进入pom.xml所在目录，如图：

执行如下命令，查看详细日志：

mvn clean package -e -X

定位到日志：

Caused by: java.lang.ClassNotFoundException: com.谷歌.common.io.Flushables

这个类在如下依赖jar包中，在pom中添加如下依赖：

1.  
   <dependency>
2.  
   <groupId>com.谷歌.guava</groupId>
3.  
   <artifactId>guava</artifactId>
4.  
   <version>20.0</version>
5.  
   </dependency>

如果依赖引入后还不行，请删除本地maven库中guava目录，重新导入： 

重新编译项目，如果没其他错误，即可成功。不幸的是，作者编译后继续报错如下：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:3.0.0:check (validate) on project devops-brain-manager-bean: Failed during checkstyle execution: There are 8 errors reported by Checkstyle 8.18 with ../../code-style/checkstyle.xml ruleset. -> [Help 1]
 

继续执行如下命令，查看详细日志：

mvn clean package -e -X

定位到日志：

There are 8 errors reported by Checkstyle 8.18 with ../../code-style/checkstyle.xml ruleset. -> [Help 1]

原因是存在多处代码不符合风格。逐个检查修改即可。
