java - 在cmd行中使用mvn安装的Eclipse项目

Question

我一直在寻找一个答案来帮助我解决这个问题，但找不到答案，也许因为我是一个 Maven 半初学者。

我的情况如下:

我安装了 Eclipse 和 maven 3.1.1，没有额外的插件。

我在 eclipse 中开发了一个项目(一个插件开发项目)，并定义了特定的目标平台。我在一个包和一个 pom.xml 文件下编写了 3 个 java 类，我保存了项目并转到命令行并在项目目录中发出“mvn clean install”，它运行时没有错误，但有一个警告“[警告]没有明确的目标运行时环境配置。构建依赖于平台”

我的主要问题是我既找不到目标目录也找不到生成的 jar 文件。现在我的具体问题是:

1-我想进入目标目录并将生成的jar文件复制到特定位置，如何在命令行中执行此操作？类似(cd/目标)2-是否有另一种方法可以从 Windows 资源管理器中打开目标目录并复制生成的 jar 文件？

我的pom.xml如下

mvn clen install后的输出如下

该版本的 Maven 与 TychoMavenLifecycleParticipant 不兼容。请参阅this post到邮件列表来解决同样的问题。已报告并修复为 bug 406056在插件的 0.18.1 版本中。

(如果您无法升级插件，advice given 仍应适用:“最好的办法是降级到 3.0.5，这对我有用。”。)
