无法加载项目（Netbeans IDE）

Question

I downloaded the archive with the project, and unpacked it. I threw it in the project folder, but when I open it through Netbeans IDE - I get an error (Project cannot be loaded) and missing package with codes It is strange that on another computer it opens a project without problems Some problems were encountered while processing the POMs:

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

Answer 1

It seems, that the project, you've copied, references another project. If you open pom.xml there probably is a section "parent" there, where a parent project is defined:

<!-- 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

This parent project probably contains dependencies with versions. Child module, you've copied, contains dependencies without versions:

<!-- 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>

You either need to copy the parent project on your computer as well or set all the dependencies versions manually.

Answer 2

This is a Spring Boot project. To have it displayed correctly in Netbeans:

• Open the project in Netbeans

• Add Maven Central to your list of repositories

• Right click on the project and run Build.

• During the build the artifact spring-boot-starter-parent is downloaded to your local maven repository and now Netbeans can display the project correctly.
