我的构建过程遇到了一些问题。
构建完成正常，Jenkins开始将文件上传到nexus。一切运作良好，但由于某种原因它失败了，最奇怪的部分是提到不上传的文件实际上传，我可以在nexus中找到它。
这是输出：

我的一位同事遇到了同样的问题，maven试图两次上传文物。 我们在论坛中找到了一些帮助，下面包含了链接。 Bae的答案为我们做了诀窍：
尝试运行mvn -Prelease-profile help：effective-pom。你会找到 你有两个maven-source-plugin执行部分
[...]
要解决此问题，请找到您使用过的所有位置 maven-sources-plugin并确保你使用＆＃34; id＆＃34; attach-sources使其与发布配置文件相同。然后 这些部分将合并。最佳实践说得到 您需要在项目的根pom中配置它的一致性 在构建＆gt;插件管理而不是你孩子的poms。在孩子身上 你只需在build＆gt;中指定pom;你想要使用的插件 maven-source-plugin但你不提供执行。
Nexus accepts upload but says it failed和Maven release plugin fails : source artifacts getting deployed twice

我也遇到过这个问题。在我的情况下，我将Nexus存储库策略配置为接受发布工件，但实际上我正在将快照工件推送到repo。由于我想要一个快照回购，我只是改变了政策，一切都很顺利。
答案 2 :(得分：1)
这也发生在我身上。就我而言，我正在部署发布版本。要解决此问题，请确保Nexus中尚不存在版本号。如果它是一个多模块项目，也要检查子模块的版本。
答案 3 :(得分：1)
快照和发布冲突也会导致400个错误请求。您尝试更新的项目可能是pom中的快照：
<version>0.0.1-SNAPSHOT</version>
而settings.xml中的存储库拒绝快照。溶液：
<version>0.0.1</version>
反过来也会发生这种情况：尝试将版本（version没有快照）版本部署到快照存储库。
