Description

This works with version 2.10, but fails with 3.0.2.

Taken the following pom.xml of a small, standalone project:

<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.example</groupId>
    <artifactId>test</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/libs-milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
    <dependencies>
        <dependency>
            <groupId>org.springframework.shell</groupId>
            <artifactId>spring-shell-starter</artifactId>
            <version>2.0.0.M2</version>
        </dependency>
    </dependencies>
</project>

The following command fails:

> mvn clean org.apache.maven.plugins:maven-dependency-plugin:3.0.2:copy-dependencies -Dmdep.addParentPoms=true
…
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:3.0.2:copy-dependencies (default-cli) on project test: Error resolving project artifact: Failure to find org.springframework.shell:spring-shell-starter:pom:2.0.0.M2 in http://uk.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of uk.maven.org has elapsed or updates are forced for project org.springframework.shell:spring-shell-starter:jar:2.0.0.M2 -> [Help 1]

Dropping the -Dmdep.addParentPoms=true causes the resolution failure to disappear, with spring-shell-starter-2.0.0.M2.jar downloading just fine:

But of course, this doesn’t download the parent POMs.

Using version 2.10 works, however.
