最近写Demo发现tomcat8插件下载不下来，百度了一下有人说是阿里云没有所以无法下载。
查找了其他仓库，发现https://artifacts.alfresco.com有tomcat8，下面配置插件下载仓库
在的的pom.xml中配置如下：
<pluginRepositories>
<pluginRepository>
<id>alfresco</id>
<url>https://artifacts.alfresco.com/nexus/content/repositories/public/</url>
</pluginRepository>
</pluginRepositories>
