Description

Maven does not detect self references in a POM and tries to download the artifact it is about to build, which makes no sense and should result in an early error and abort of the build.

E.g. sample POM:

    <groupId>org.my.acme</groupId>
    <artifactId>my-module</artifactId>
    <version>1.2.3</version>
    <dependencies>
        ...
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>my-module</artifactId>
            <version>${project.version}</version>
        <dependency>
    <dependencies>

Maven tries to download my-module.jar but obviously fails...
