Short description

org.apache.maven.plugin.MojoExecutionException: Cannot fill out VersionInfo by defaults: 'project.version' is in invalid format. Regex pattern: ^((\d(\.)?)*\d+)(-\w+)?$

When using 0.1-20260316-NIGHTLY as project.version

Steps to reproduce

1. use 0.1-20260316-NIGHTLY as project.version, or something isn't strictly numbers separated by dots and use 0.1.20260316 as winVersion
   And

<winConfig>
<fileVersion>${winVersion}</fileVersion>
<txtFileVersion>${winVersion}</txtFileVersion>
<productVersion>${winVersion}</productVersion>
<txtProductVersion>${winVersion}</txtProductVersion>
</winConfig>
<version>${winVersion}</version>

2. try packaging for windows

Expected behavior

It should use winVersion, which is in the correct format and not throw an error

Actual behavior

Java packager throws an error because it still checks project.version, even when it isn't referenced anywhere.
It should probably allow for any text in the project.version, because this also restricts versions like -SNAPSHOT.

I also took a loot at target/launch4j/app.exe.manifest and it looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">

                </application>
        </compatibility>
</assembly>

I can't figure out where version="1.0.0.0" comes from, I though it was the default value for <productVersion>1.0.0.0</productVersion> and <fileVersion>1.0.0.0</fileVersion> but I overwrite them in the plugin configuration.
