背景：我正在封闭网络中的Maven项目，这意味着我无法连接到Maven
Central。我有一个存储库文件夹，其中包含我需要的所有工件，包括插件和Maven工件。另外，我无法使用或安装Nexus。

问题：我想使用maven 3.6.0 / jdk 1.8.0_162运行Jenkins作业。我的settings.xml文件如下：

我的POM没有存储库部分，因为jenkins从属服务器应确定从何处获取这些存储库。

构建时，虽然出现以下错误：

[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its dependencies could not be resolved: Could not find artifact org.apache.maven.plugins:maven-clean-plugin:jar:2.5 in ExternalRespositoryMirror (file://myserver/repository/maven/repository) -> [Help 1]

我可以打开文件：// url，工件“ maven-clean-plugin-2.5.jar”位于文件夹\ maven \ repository \ org
\ apache \ maven \ plugins \ maven-clean-plugin \ 2.5中

Maven找不到工件的原因可能是什么？它存在于本地存储库（D：\ Maven \ repository）中，因此无论如何它实际上不应查询网络存储库。
