Maven 组装插件在 Jenkins 中重新下载依赖性
原标题：Maven assembly plugin redownloading dependencies in jenkins

出于某种原因, Maven 每次我试图和Jenkins一起建造项目时, 似乎都在试图下载我的项目依赖关系。 有几个问题。 第一个问题是它根本不应该这样做, 另一个问题是它甚至没有试图从正确的回购中下载它们, 这意味着它必须等待它们每个人的暂停时间。

我可以自己运行 mvn 干净的软件包, 它在~ 4 秒内建造它, 因为所有依赖性都在我的当地. m2 repo。 Jenkins 是在本地安装的, 并且正在分享这个maven repo, 所以我不知道它为什么表现不同。 Jenkins 正在用 -B 和 -f 的旗帜发布maven 命令, 并且正在使用安装而不是软件包, 但即使我自己这样做, 它也会在几秒钟内完成, 而 Jenkins 需要大约8 分钟的时间, 因为它需要等待所有的时间。

我标记了Slick2d和lwjgl图书馆, 因为我觉得这和它们有关, 因为它们不是在公共的maven repo里,

唯一不同的是Jenkins花八分钟的时间超时, 而我自己却在几秒内完成。

另外,当我试图弄明白 最初,当我想手工做的时候,它也会发生。它停止这样做,因为我添加了马文原住民仓库, 但我不知道为什么詹金斯仍然在花时间, 因为他们分享相同的当地回购,

更新:在试图弄清楚究竟发生了什么之后, 我似乎缩小了范围, 将其与马文组装插件有关, 因为如果我把那个部分从我的口袋里拿出来, 效果会很好。
