【问题描述】：

我正在尝试使用 Gitlab-Ci 将 maven 项目部署到我们的 Nexus，但在尝试上传由 maven-shade-plugin 创建的 shaded-jar 时，管道总是失败。任何想法为什么会这样？

管道错误：

【解决方案1】：

看起来我使用了错误的 maven 图像。我刚刚使用了 maven:latest，但是当我将其更改为 maven:3.6.2-jdk-8 时，它又可以工作了。

【讨论】：

有趣。赞成。 Docker maven 最新 (hub.docker.com/_/maven) 是 3.6.2-jdk-11，所以，正如我在答案中提到的，可能存在 TLS 问题。

【解决方案2】：

错误是：

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) 
  on project MyPlayPlanet-Core: 

Failed to deploy artifacts: 

Could not transfer artifact net.myplayplanet:MyPlayPlanet-Core:jar:shaded:1.14.0-20190929.002150-7 
from/to pp-snapshots (https://nexus.myplayplanet.net/repository/myplayplanet-snapshots/)

Connection reset by peer (Write failed)

检查快照工件的大小，可能存在大小限制问题。

还要检查您在本地使用的 JDK 版本，如 this issue

通过以下方式禁用 TLS 1.3 协议：
-Djdk.tls.client.protocols="TLSv1,TLSv1.1,TLSv1.2"
