出于某种原因,每当我尝试使用Jenkins构建它时,maven似乎都在尝试下载我的项目的依赖项。有一些问题。第一个是它根本不应该这样做,另一个问题是它甚至没有尝试从正确的仓库下载它们,这意味着它必须等待它们中的每一个超时。
我可以自己运行mvn clean包,并在~4秒内构建它,因为所有依赖项都在我的本地.m2 repo中。 Jenkins在本地安装并且正在共享这个maven repo,所以我不知道它为什么表现不同。似乎jenkins正在使用-B和-f标志发出maven命令并且正在使用install而不是package但是即使我自己这样做它也会在几秒内完成,而Jenkins需要大约8分钟,因为所有的超时它必须等待。
我标记了Slick2d和lwjgl库,因为我认为它与它们有关,因为它们不在公共maven仓库中,我必须手动将它们的repo添加到pom中。
也许值得注意的是,构建完成并且是成功的,唯一的区别是Jenkins在超时上花了8分钟,而自己在几秒钟内完成。
另外,当我试图解决这个问题时,当我尝试手动完成时也会发生这种情况。在我添加了Maven Natives Repository之后它停止了这一点,但我不知道为什么Jenkins仍在花时间,因为他们共享相同的本地仓库和
更新:在试图找出正在发生的事情后,我似乎已将其缩小为与maven程序集插件相关,因为如果我从我的pom中取出那部分它可以正常工作。

获得稳定的Maven构建的第一步是使用Maven Repository Manager,例如Nexus。
完成此操作后,请检查行为并告诉我们您是否有任何问题。

似乎maven程序集插件是尝试下载内容的原因所以我用maven shade插件替换它,这让我排除了一些我想要排除的文件。不确定这是否是最好的解决方案,但它适用于我的情况。结束了我的构建时间从8分钟减少到25秒。
这是我在取出程序集插件的jar-with-dependencies部分后添加到我的pom中的内容。
