Spring dependency not found

Time:01-01

I'm very new to Spring, and also Maven. I'm following along with the book Spring Start Here because it seems friendly. The very first project asks us to add a spring-context dependency to a new project (using maven). I'm using the Intellij Idea community version to follow along, as suggested in the book. But on following the instructions to add the dependency I get an error: Dependency 'org.springframework:spring-context:' not found

Here is my pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.myspring</groupId>
    <artifactId>start</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </dependency>
    </dependencies>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

</project>

I think the idea is to add spring dependencies one by one in order to see their purpose. The autocompletion in idea shows an error for the lines

<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>

Edit: I just removed the empty version tag in the dependency.

CodePudding user response:

maven usually requires the version tag to specify the version Most cases where no version is specified are when the project inherits pom files For example

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.0.0</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

Unlike npm and pip, it does not automatically select the latest version
