尝试查找依赖项目时 Maven 安装失败答案

【问题标题】：Maven install is failing while trying to look for dependent project尝试查找依赖项目时 Maven 安装失败
【发布时间】：2020-06-25 19:28:03
【问题描述】：

我有一个依赖于 tos-base 的 order-core 项目。这是我的 pom.xml。我尝试了所有可能的堆栈溢出问题，但仍然出现错误。

我关注了

mvn 清洁 mvn 编译 mvn 编译依赖：树 mvn 干净安装

另外，我尝试使用 Xms 和 Xmx 设置 MAVEN_OPT。

另外，我再次创建了项目，但同样的错误。

【问题讨论】：

什么是tos-base？
这是另一个项目，其中包含我们所有项目的基本功能。并且 order-core 依赖于这个项目。我可以为 tos-base 项目创建 jar 文件，它位于 .m2/repository 以及我的本地存储库中。
可以添加错误信息吗？
编辑帖子以在帖子底部添加错误。
您使用的是 Nexus 或 Artifactory 等存储库吗？ com.spectrum.tos:tos-base:1.0:jar 是否存在依赖项？如果没有，如果您进行了更改，您的安装（上述项目上的mvn install）是否首先安装了 tos-base 依赖项？（最后但并非最不重要的一点是，您可能想查看项目反应器，以便 Maven 知道如何正确编译您的项目）。

标签： maven-3

【解决方案1】：

尝试mvn -U clean install从你的远程仓库重新更新本地仓库，如果你的本地仓库.m2/com/spectrum/tos下正确安装了tos-base依赖，那么你应该检查1.0版本是否真的包含缺少包也许你应该升级这个依赖。

【讨论】：

这是我的本地存储库。 C:\Users\P2932832\.m2\repository\com\spectrum\tos\tos-base\1.0>jar -tvf tos-base-1.0.jar 这里是文件 2448 Fri Mar 13 11:00:54 MDT 2020 BOOT-INF/classes/com/spectrum/tos/model/Order.class 733 Fri Mar 13 11:00:56 MDT 2020 BOOT-INF/classes/com/spectrum/tos/BaseApplication.class 2805 Fri Mar 13 11:00 ：54 MDT 2020 BOOT-INF/classes/com/spectrum/tos/model/OrderRequest.class。我有所有的课程，我今天自己创建了 tos-base-1.0.jar。我还在eclipse中做了maven update project来同步。 mvn -U clean install 没有帮助并得到同样的错误。
我尝试构建另一个依赖 tos-base 的项目。我得到了同样的错误包 com.spectrum.tos.builder 不存在。我试图删除 .m2/repository 中的文件夹并再次创建 jar 并遇到同样的问题。不知道如何解决问题。
我可以从您的类位置 (/BOOT-INF) 中看到您正在使用 Spring Boot 应用程序作为依赖项，这导致编译失败
这个问题和你的类似stackoverflow.com/questions/53679361/…
瓦法，非常感谢。我尝试放置 exec classifier ，它起作用了。由于推荐的方法是模块化。我做了同样的事情，效果也很好。
