git-changelog-lib: execution stuck

Hi. I tried this basic config on my project.

    <plugin>
      <groupId>se.bjurr.gitchangelog</groupId>
      <artifactId>git-changelog-maven-plugin</artifactId>
      <version>1.64</version>
      <executions>
        <execution>
          <id>GenerateGitChangelog</id>
          <phase>generate-sources</phase>
          <goals>
            <goal>git-changelog</goal>
          </goals>
          <configuration>
            <templateContent>
              <![CDATA[
# Changelog
Changelog of My Project.
              ]]>
            </templateContent>
            <skip>false</skip>
          </configuration>
        </execution>
      </executions>
    </plugin>

When I run mvn clean install -e -X the output goes on ad infinitum.
