artifactIdmaven-dependency-plugin/artifactId
version2.8.1/version
configurationincludescom.jdriven:*/includesexcludes/
/configuration 可以定义包含或排除过滤器以将依赖项放在范围内或放在范围之外以进行中介检查。 请注意示例配置过滤器还用于依赖项插件支持的其他目标。 可以轻松地将目标依赖项中介添加到您的Jenkins构建配置中以防止您使用未经检查的版本中介发布项目。 在向中介插件版本2.8添加中介功能所需的补丁下方。 玩得开心 补丁 Index: src/main/java/org/apache/maven/plugin/dependency/mediation/VersionMediationException.java--- src/main/java/org/apache/maven/plugin/dependency/mediation/VersionMediationException.java (revision 0)src/main/java/org/apache/maven/plugin/dependency/mediation/VersionMediationException.java (working copy)-0,0 1,15
