我有两个配置文件 - dev（默认情况下处于活动状态）和 release（由发布插件激活）。首先，我在发布版本时遇到了 ant run（文件路径）的一些问题，所以我使用了两个定义了一些属性的配置文件，它们在 ant run 中使用。 Ant 脚本现在已正确执行，但我还有另一个问题：插件尝试两次上传某些发布文件导致错误：

执行 mvn release:prepare "-Darguments=-Dmaven.test.skip=true": log

执行 mvn release:perform "-Darguments=-Dmaven.test.skip=true": log

您可以看到表单日志，Test-WAR-0.0.1-sources.jar 正在上传两次。这是为什么？如何编辑我的配置以仅上传一次？

【问题讨论】：

这些deploy:deploy-file 要求什么？您是否尝试使用deploy-file 部署构建结果？为什么跳过了正常的部署步骤？
@JFMeier deploy:deploy-file部署ant run生成的jar文件。跳过了正常部署，因为我只需要部署 ant run 生成的这两个 jar 文件，而不是整个 war 模块。这甚至可能吗？我不知道为什么在“deploy-ejb-client”执行时会发生战争部署，你能解释一下吗？
这导致了 Ant 和 Maven 之间的奇怪混合，并可能导致各种问题。通常，您通过 Maven 为每个模块创建一个工件，然后在部署阶段自动部署该工件。
清理 pom 很可能会解决问题，即开始删除每个 maven-deploy-plugin 和 maven-antrun-plugin。如果不成功，请分析该问题。

标签： maven pom.xml maven-release-plugin

【解决方案1】：

很可能你遇到了和我几年前一样的错误：

Maven deploy-file goal: Why does the first execution interfere with the second one?

尝试将 Maven 部署插件更新到版本 3.0.0-M1。

有效！我从来没有想过。非常感谢！
