用这个地址下载https://sourceforge.net/projects/eclipse-cs/?source=typ_redirect，Eclipse Checkstyle Plug-in 版本号8.7.0.201801131309 插件安装就可以了。 插件说明: The Eclipse Checkstyle plug-in integrates the Checkstyle Java code auditor into the Eclipse IDE. The plug-in provides real-time feedback to the user about violations of rules that check for coding style and possible error prone code constructs.
