package org.springframework.web.bind.annotation does not exist even though it's defined in POM

Question

So I have this code

import org.springframework.web.bind.annotation.GetMapping;

And I already have the following in my POM file

<packaging>war</packaging>
    <properties>
        <spring.version>4.3.0.RELEASE</spring.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>
    </dependencies>

Yet when I built it ends up complaining package org.springframework.web.bind.annotation does not exist

Why? I already added spring web as a dependency. What am I doing wrong?

Run the following command

mvn clean install

If you are using IDE like intelliJ idea or Eclipse make sure to re import the project. Here is an answer how to refresh maven dependencies in eclipse

Trying:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>

        </dependency>

    <build>

Answer 4

For me, removing the spring-web dependency worked. To do this, remove the following from your pom.xml:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>${spring.version}</version>
</dependency>

Answer 5

I had a similar issue, I fixed it by going into my pom.xml file and changing the artifactID for the spring boot dependency from:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
</dependency>

to

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
</dependency>

Edit to show explanation:

I was following a tutorial that had me using the wrong dependency. If I remember correctly, the spring-boot-starter-web dependency contains everything spring-boot-starter has, plus what you need to make a basic web app. So my app was looking for some web dependencies that I'm assuming spring-boot-starter does not contain.

Clean install doesn't fixed issue for me. I clicked in Maven (right tab in Intelij) and then refresh button. Maven downloaded everything and it works now
