tomcat9-jenkins：insufficient free space available after evicting expired cache entries-consider

解决该问题方法，修改tomcat/conf/context.xml文件，增加资源最大可缓存的大小：

<Context>

    <!-- Default set of monitored resources. If one of these changes, the    -->
    <!-- web application will be reloaded.                                   -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <WatchedResource>WEB-INF/tomcat-web.xml</WatchedResource>
    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
<Resources
        cachingAllowed="true"
        cacheMaxSize="100000"
    />
    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    -->
</Context>
