Spring dependency not found

Question

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>

• I have already tried updating the maven>repositories in the ide settings but still get the same error.
• Also, I found the page https://mvnrepository.com/artifact/org.springframework/spring-context which seems to suggest I have used the correct groupId and artifactId names

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

Answer 1

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
