I decided to update my spring-boot-starter-parent to version 2.0.0.M1 in order to use it with Spring Core 5.0.0.RC1.

But, i am having issues downloading the dependency from the Spring milestone repository.

My pom.xml

To use spring-boot milestone versions, add following to pom.xml, between <project></project>:

<repositories>
    <!-- for spring milestone -->
    <repository>
        <id>spring.milestone</id>
        <url>http://repo.spring.io/milestone</url>
    </repository>
</repositories>
<pluginRepositories>
    <!-- for spring milestone -->
    <pluginRepository>
        <id>spring.milestone</id>
        <url>http://repo.spring.io/milestone</url>
    </pluginRepository>
</pluginRepositories>

Add the following into your pom.xml file.

 <repositories>
    <repository>
        <id>spring-snapshots</id>
        <name>Spring Snapshots</name>
        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

<pluginRepositories>
    <pluginRepository>
        <id>spring-snapshots</id>
        <name>Spring Snapshots</name>
        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </pluginRepository>
    <pluginRepository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>

I suggest you update the Spring Boot version to the latest to get newest dependencies, currently it is 2.0.0.M6 which includes Spring 5.0.1.RELEASE in its dependencies management. 

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.M6</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

Or generate a new Spring Boot 2.0 based project from Spring Initializer, all dependencies will be resolved.

to fix this, try to click the reimport all maven projects button: enter image description here:

I didn't have a "clean sheet" settings.xml because I have a personal mirror URL in place. The only way to fix this issue was to include @Hantsy answer in my settings.xml instead of the pom.xml

If you are in China, you can fix this problem by modifying the settings.xml file like this:

<mirror>
    <id>nexus-aliyun</id>
    <mirrorOf>*</mirrorOf>
    <name>Nexus aliyun</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>

settings.xml path of mine:C:\Program Files\apache-maven-3.6.0\conf\settings.xml

The question is bit old, but I am updating here hoping that it might help someone.

In my case, work offline has been checked and hence I was getting error.

Here is the fix I have made. in Mac, navigate to IntelliJ menu and select preferences or short cut key(Command + ,).

Search maven and select. then uncheck work offline if it is checked already.

I got the same issue in Intellij and was able to resolve it by using Invalidate Caches.

  • Open the File menu and select "Invalidate Caches" from the dropdown menu.

    enter image description here

  • From here you will be prompted with a few options. Select the checkbox for Clear downloaded shared indexes.

enter image description here

  • Finally, click the Invalidate and Restart button and IntelliJ will reload and re-index your project’s Maven dependencies.
