Question

我构建了常见项目并将其安装到本地存储库，然后我尝试使用相同的jar包，但计算机找不到它。

首先，我在我的本地存储库中构建并安装common：

F:\seprate\paymate-commons>mvn -DskipTests install

之后我尝试建立依赖于paymate-commons的paymate模型

F:\seprate\paymate-model>mvn -o -DskipTests install

我发现没有配合我使用mvn -DskipTests安装或mvn -DskipTests安装我不使用本地存储但我可以在默认的本地存储库中找到jar文件。

C:\Users\Username\.m2\repository\au\com\paymate\paymate-commons\2.6.9

如何让电脑知道罐子的位置并使用它？我是否需要在pom.xml上进行一些设置？

Answer 1

您需要在setting.xml（不是pom.xml）上进行一些设置！找到您的maven目录，然后编辑conf/setting.xml。查找<localRepository>节点，编写.jar文件目录！

Answer 2

您可以尝试几种选择。

清理au.com.paymate文件夹并使用
重新运行付款公共文件
mvn -U clean install

然后运行您付款模式
使用absolute path

Answer 3

正如Gonzalo Matheu指出的那样，你错过了依赖

au.com.paymate:projects:pom:2.6.9

在名称之后，它应该是项目的一部分。也许你只是在构建一个更大的项目的一个模块？或者您忘了先创建另一个相关项目？

在任何情况下，构建都会失败，因为au.com.paymate:projects:pom:2.6.9不在您的本地存储库中，因此您必须从另一个存储库获取它，或者您必须自己从相关项目构建它。

如何在maven中使用本地重新定位？
