Usage

 Some brief examples on how to use this plugin.

* Signing a project artifact and attachments

  If you need to sign a project artifact and all attached artifacts, just
  configure the sign goal appropriately in your <<<pom.xml>>> for the
  signing to occur automatically during the package phase.

+-----------------+
<project>
  ...
  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jarsigner-plugin</artifactId>
        <version>${project.version}</version>
        <executions>
          <execution>
            <id>sign</id>
            <goals>
              <goal>sign</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <keystore>/path/to/the/keystore</keystore>
          <alias>Alias name</alias>
          <storepass>Store password</storepass>
          <keypass>Key password</keypass>
        </configuration>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>
+-----------------+

  <<Since version 1.3>> you can encrypt <<<keypass>>> and <<<storepass>>> using the
  maven encryption mechanism.

  See {{{https://maven.apache.org/guides/mini/guide-encryption.html}Maven encryption guide}}.

* Verifying the signature of a project artifact and attachments

  If you need to verify the signatures of a project artifact and all attached
  artifacts, just configure the verify goal appropriately in your <<<pom.xml>>>
  for the verification to occur automatically during the verify phase.

+-----------------+
<project>
  ...
  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jarsigner-plugin</artifactId>
