"Could not determine gpg version"

[yetyman]

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

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 as referenced by gnupg.org

Hey, have you managed to figure this out? The way deploying to maven was changed in 2025, and I'm completely stuck.

Ideally you (two of you) should figure out what is happening... can you run the plugin in debug maybe and paste the output in gist or whatever?
