Indicate updated version for maven central and automation tools

[Lonzak]

There are new versions of this project available. But for the new versions 1.2.4 and 1.2.5 the groupId of the artifact was changed - thus it seems that the old version is still the most current:

It would be really helpful for users and for automation tools like dependabot/renovatebot to be aware of this. There is an official mechanism for that. For example:

The idea is that the first new version (1.2.4) is once also released with the old groupId but with a minimal pom and a relocation entry:

<project 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.wisepersist</groupId>
<artifactId>gwt-uploader</artifactId>
<version>1.2.4</version>
<name>gwt-uploader</name>
...
<distributionManagement>
    <relocation>
        <groupId>org.docstr</groupId>
        <artifactId>gwt-uploader</artifactId>
        <message>
            GWT-uploader moved to the new location due to a domain change.
        </message>
    </relocation>
</distributionManagement>

Not sure if I'm able to create a new release based on the old groupId.

Maybe there is a way to do it the other way around... I'll check it

Ok I have read how it is done:

First a minimal pom.xml file for version 1.2.4 (not for 1.2.3 as I originally thought) would be created but under the old groupId. The POM files only need to include groupId, artifactId, version and the relocation section:

<project 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.wisepersist</groupId>
    <artifactId>gwt-uploader</artifactId>
    <version>1.2.4</version>
    <url>https://jiakuan.github.io/gwt-uploader/</url>
    <distributionManagement>
        <relocation>
            <groupId>org.docstr</groupId>
        </relocation>
    </distributionManagement>
</project>

Not sure if I'm able to create a new release based on the old groupId.

Yeah, that would be a prerequisite to be able to do a (last) one time release under the old groupId... I hope it is possible because I think many people just don't know that there is a new version out there...

Thanks. I will have a look when I get a chance.
