Netbeans中通过maven安装jar看不到pom.xml的位置

Question

我在 Netbeans 中有一个 Maven 项目。

我在本地有一个要插入到项目中的 jar。

通过 cmd 我运行命令

C:\Users\Alia-PC>mvn install:install-file-Dfile=C:\opt\glassfish4\glassfish\dom ains\domain1\applications\myproject\files\rrunner_ja r\Ropt-Updated.jar \ -DgroupId=rcaller -DartifactId=RCaller \-Dversion=2.4 -Dpackaging=jar -e

但我收到 pom.xml 的此错误。

即使我试着做一个

cd C:\opt\glassfish4\glassfish\domains\domain1\applications\myproject\

谁能告诉我问题的原因以及如何解决？

Answer 1

这是一个两步过程：

在本地安装 3rd 方 jar：

mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>

使 jar 可用于您的项目：

在您的pom 中指定 jar 依赖项，使用您在本地安装它并从项目目录构建项目时定义的相同细节。

<dependency>
            <groupId>Specified GroupID</groupId>
            <artifactId>Specified ArtifactID</artifactId>
            <version>Specified Version</version>
  </dependency>

这个错误告诉我的是你试图从一个没有定义pom 的项目目录以外的目录构建。

理想的 Maven 文件夹结构：

Project
      |
      ---src
           |
           ---main
                 |
                 ---java
                 ---so on
           ---test
                 |
                 ---so on
      ---Pom.xml
