java - 无法加载项目(Netbeans IDE)

Question

我下载了该项目的存档，并将其解压。我把它放在项目文件夹中，但是当我通过 Netbeans IDE 打开它时 - 我收到错误(项目无法加载)并且缺少包含代码的包 奇怪的是在另一台电脑上打开项目却没有问题 处理POM时遇到一些问题:

[ERROR] 'dependencies.dependency.version' for org.springframework.boot:spring-boot-starter:jar is missing. @ line 22, column 21

Answer 1

您复制的项目似乎引用了另一个项目。如果您打开 pom.xml，那里可能有一个“parent”部分，其中定义了父项目:

<!-- Identifier of the parent project -->
<parent>
    <groupId>...group of your parent project...</groupId>
    <artifactId>... artefactId of your parent project ...</artifactId>
    <version>... version of your parent project ...</version>
</parent

此父项目可能包含版本依赖项。您复制的子模块包含没有版本的依赖项:

<!-- Version of the dependency is defined in parent pom in dependencyManagement section -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!-- here should be the version -->
</dependency>

您还需要复制计算机上的父项目，或者手动设置所有依赖项版本。
