Maven 构建成功，但在目标文件夹中没有结果答案

【问题标题】：Maven Build Success, but no result in target folderMaven 构建成功，但在目标文件夹中没有结果

【问题描述】：

对于初学者来说，我与 Maven 的合作并不多。

除了未指定版本外，我一切正常，但是当我在 pom.xml 中指定了 Maven 版本时，它仍然无法正常工作。

注意：每次运行都显示“构建成功”，但没有人将完成的 jar 文件放在目标文件夹中，这是我认为应该发生的。

这是我的 eclipse 输出：

标签： java eclipse maven

【解决方案1】：

输出显示

Building jar: C:\Users\Roboverse\eclipse-workspace\VoluntaryPullFromEternity\target\VoluntaryPullFromEternity-0.0.1-SNAPSHOT.jar

因此，如果您在目标中没有看到 JAR，您可能需要刷新 Eclipse。如果可以找到该文件，请查看 Windows 资源管理器（或某些 Linux 等效项）。
