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>3.0.0</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.

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>
        <version>3.0.0</version>
        <executions>
          <execution>
            <id>verify</id>
            <goals>
              <goal>verify</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <verbose>true</verbose>
          <certs>true</certs>
        </configuration>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>
