yetyman opened a new issue, #137:
URL: https://github.com/apache/maven-gpg-plugin/issues/137
### Affected version
3.2.6
### Bug description
I am setting up central publishing with maven and have added this maven
plugin.
```
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-gpg-plugin</artifactId>
<version>3.2.6</version>
<executions>
<execution>
<id>sign-artifacts</id>
<phase>verify</phase>
<goals>
<goal>sign</goal>
</goals>
</execution>
</executions>
</plugin>
```
upon trying to deploy i receive this error message
"Could not determine gpg version"
I traced this back to [this line of the
plugin](https://github.com/apache/maven-gpg-plugin/blob/master/src/main/java/org/apache/maven/plugins/gpg/GpgSigner.java#L74)
After reviewing the regex that is used to get the version
`Pattern.compile("gpg \\([^)]+\\) .+");`
And then the regex used to match the value `VERSION_PATTERN =
Pattern.compile("(\\d+\\.)+(\\d+)")`
And reviewing my terminal's `gpg --version` call
```
C:\Users\MY_USERNAME>gpg.exe --version
gpg (GnuPG) 2.4.8
libgcrypt 1.11.1

I don't see why this failure has occurred in my build. Any help would be
appreciated.
My gpg came from [gpg4win.org](https://gpg4win.org/download.html) as
referenced by [gnupg.org](https://www.gnupg.org/download/)
