zrlw opened a new issue #8868: URL: https://github.com/apache/dubbo/issues/8868
### Environment * Dubbo version: 3.0 / master 比如 https://github.com/apache/dubbo/runs/3665650264?check_suite_focus=true ``` Error: Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test (default-test) on project dubbo-common: Unable to generate classpath: org.apache.maven.artifact.resolver.ArtifactResolutionException: Could not transfer artifact org.opentest4j:opentest4j:jar:1.1.1 from/to central (https://repo.maven.apache.org/maven2): Entry [id:2457][route:{s}->https://repo.maven.apache.org:443][state:null] has not been leased from this pool ``` 1. 看了一下workflow，发现windows构建有设置maven.wagon.http.pool=false，但是这个选项是wagon http2.0才支持的，dubbo-parent的pom.xml里面配置的maven-surefire-plugin版本是2.22.2，这个版本引用的wagon http版本是1.0-beta-6，所以配了maven.wagon.http.pool也没有效果。 2. 搜了一下Could not transfer artifact ... has not been leased from this pool，其他开源软件也有出现，比如Pulsar，Flink，有篇帖子说问题在于wagon http使用的HttpClient组件版本太老，有HTTPCLIENT-1453线程安全缺陷（https://issues.apache.org/jira/plugins/servlet/mobile#issue/HTTPCLIENT-1453），解决办法要么把maven-surefire-plugin版本换成3.0.x，不用wagon了（升大版本存在兼容风险），要么把wagon http升到最新的3.4.3（使用了没有上述缺陷的新版HttpClient）。 下面这个帖子讨论的很详细，很长，我还没看完，里面有句```The Alibaba machines are probably running in a somewhat unstable network environment```，感觉是阿里的同学或者和阿里的客户。 https://issues.apache.org/jira/browse/FLINK-16947?focusedCommentId=17285028&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17285028 -- This is an automated message from the Apache Git Service.
