bitbucket管道无法下载maven工件

Question

使用bitbucket管道遇到以下问题，但无法找出它可能发生的原因 - 在构建过程中我经常看到以下错误：

其他的libs下载得很好，在我将before-after-spring-test-runner库添加到pom.xml后问题就出现了。即使在完全repo清理之后，本地构建也会像往常一样从IDE和CLI运行。 有人能说出这两个事实之间可能存在什么联系？ :)

在最后一次基础架构更新后，管道开始关闭闲置超过5分钟的空闲Maven连接。这会影响运行Maven并且花费的时间超过这段时间的任何构建，因为这样的构建将因“连接重置套接字异常”而失败。

运行集成测试后会触发Maven生命周期中的某些插件，唯一的解决方法是强制Maven在每个使用请求时使用新连接

mvn -Dmaven.wagon.http.pool=false clean install

但是，这会影响构建时间。
