Usage

Key configuration provided in pom

<plugins>
    <plugin>
        <groupId>org.simplify4u.plugins</groupId>
        <artifactId>sign-maven-plugin</artifactId>
        <version><!-- check releases page --></version>
        <executions>
            <execution>
                <goals>
                    <goal>sign</goal>
                </goals>
                <configuration>
                    <keyId><!-- key id in hex --></keyId>
                    <keyPass><!-- private key passphrase --></keyPass>
                    <keyFile><!-- private key file location --></keyFile>
                </configuration>
            </execution>
        </executions>
    </plugin>
    ...
</plugins>

Key configuration provided in environment variables

Key configuration can be provided by environment variables: SIGN_KEY, SIGN_KEY_ID, SIGN_KEY_PASS.

When using environment variables for configuration, SIGN_KEY - must contain private key content - not file path for key

So your pom configuration can be simplified to:

<plugins>
    <plugin>
        <groupId>org.simplify4u.plugins</groupId>
        <artifactId>sign-maven-plugin</artifactId>
        <version><!-- check releases page --></version>
        <executions>
            <execution>
                <goals>
                    <goal>sign</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
    ...
</plugins>
