当前，我面临的问题是我试图在代理后面建立S4SDK jenkins管道。
为此，我相应地调整了server.cfg中的配置，并且在Jenkins服务器日志中也显示使用了此配置：
Setting Jenkins network proxy to <IP of proxy>:<port of proxy> without using credentials. No proxy patterns: [*localhost, *127.0.0.1, *s4sdk-nexus]
但是，在管道执行期间，更具体地说，在最后执行s4sdkQualityChecks时，checkHystrix.groovy脚本使用grapes提取另一个依赖项：
@Grab('com.xlson.groovycsv:groovycsv:1.1')
但是，无法解决此依赖关系，并显示以下堆栈跟踪：
org.jenkinsci.plugins.workflow.cps.CpsCompilationErrorsException: startup failed:
General error during conversion: Error grabbing Grapes -- [unresolved dependency: com.xlson.groovycsv#groovycsv;1.1: not found]
java.lang.RuntimeException: Error grabbing Grapes -- [unresolved dependency: com.xlson.groovycsv#groovycsv;1.1: not found]
