Maven can't find existing dependency in Maven Central-CodePudding

I have a new Spring Boot 2.5.3 project and got some weird issue. I am trying to add this dependency in my pom.xml, but Maven 3.6.3 can't resolve the dependency for some reason.

        <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi</artifactId>
            <version>1.5.10</version>
        </dependency>

When running mvn clean install -U both from IDE (IntelliJ) and command prompt (bash / cmd), the printed exception is

The dependency exists in Maven Central which makes things weird.

Tried on 2 different machines with Windows and CentOS operating systems and the result is the same.

CodePudding user response：

This dependency does not have a jar type. It's POM type only.

You need to use the same dependency declaration as the Maven Central suggests:

<!-- https://mvnrepository.com/artifact/org.springdoc/springdoc-openapi -->
<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi</artifactId>
    <version>1.5.10</version>
    <type>pom</type>
</dependency>

CodePudding user response：

Try doing a maven clean install

The clean goal should recompile the project and recognize the new dependency. If that does not work, try to close down the IDE and restart it.

If the dependency is in fact in Maven central I am confident the clean goal will work.

Both of these options have worked for me in the past regarding dependency issues.
