Maven 构建在下载工件时重置连接

java maven amazon-ec2 jenkins maven-central
2022-09-03 15:30:21

我们有一个 maven 构建，它在 amazon ec2 实例的 jenkins 中运行。总构建需要20-30分钟，大约每隔一次运行就会失败，因为它无法从maven central下载工件。这是日志的失败部分：

有趣的是，它可以从maven central和我们自己的存储库下载20分钟，但每隔一次在完全相同的下载中失败。这让我认为这不是由于连接问题，因为这样它会在其他下载上随机失败。

在谷歌搜索之后，我发现这可能是由于Ipv4与Ipv6问题，所以我尝试在构建中设置java.net.prefetIPv4stack=true，但这没有帮助。

运行 mvn 的命令是：

mvn -X -e clean deploy -U -Djava.net.preferIPv4Stack=true

我还尝试在MAVEN_OPTS和JAVA_OPTS中增加-Xmx（我在某处读到，maven需要能够将所有依赖项保留在RAM中，不确定是否为真），但没有成功。

你还有其他想法可以尝试吗？

编辑：添加了堆栈跟踪

答案 1

TL;DR

尝试升级到 Maven 3.6.1。它具有新版本的Wagon HTTP，具有改进的重试行为。这为我们解决了问题。

背景

我们的构建运行良好了几个月（在ec2中）。然后有一天，他们开始偶尔失败地下载Maven工件（从Maven中心）与连接重置。我们从未深入探讨过它。也许 ec2 中的某些内容发生了变化。也许我们构建中的某些内容发生了变化。邓诺。

最重要的是网络不可靠，Maven（或者更具体地说是Wagon）对连接故障的弹性不高。值得庆幸的是，看起来他们已经改进了这一点。

Maven 3.6.1 包括一个新版本的 Wagon，支持可配置的重试行为。默认情况下，它的重试计数似乎为 3 - 这对我们来说已经足够好了。一些细节：


答案 2

几个指针，

1） 这看起来像是 EC2 网络设置问题。这不是一个熟练的http wagon问题。

2）看看这个类似的问题。更具体地说，这是。

3）您可以暂时尝试以下操作。

sudo sysctl -w net.ipv4.tcp_keepalive_time=60
sudo sysctl -w net.ipv4.tcp_keepalive_intvl=60
sudo sysctl -w net.ipv4.tcp_keepalive_probes=10

希望它能帮助你解决问题。
