Maven deploy artifact to nexus repository is failing with gpg key missing errors

Question

I'm trying to deploy my local artifact into the nexus staging repository but the task is failing with the below error.

gpg: no default secret key: No secret key
gpg: signing failed: No secret key
[INFO] ------------------------------------------------------------------------

[INFO] Finished at: 2021-06-14T14:12:29+05:30
[INFO] -----------------------------------------

Steps I followed.

1. I have installed the gpg using brew.
2. gpg version is

     gpg (GnuPG) 2.3.1
     libgcrypt 1.9.3
   

3. I have added the setting.xml to .m2 directory path - ~/.m2/settings.xml
4. Here is the my settings.xml file

<settings>
<servers>
 <server>
   <id>ossrh</id>
   <username>$name</username>
   <password>$password</password>
 </server>
</servers>
<profiles>
 <profile>
   <id>ossrh</id>
   <activation>
     <activeByDefault>true</activeByDefault>
   </activation>
   <properties>
     <gpg.executable>gpg</gpg.executable>
     <gpg.passphrase>$passphrase</gpg.passphrase>
   </properties>
 </profile>
</profiles>
</settings>

5. I have imported the .asc file using gpg --import file.asc

6. when I run gpg --list-keys command, I'm able to see the pub, uid & sub key values.

7. My current mvn version is Apache Maven 3.6.3

8. I have updated my project module pom.xml with the below values

            <plugin>
                <groupId>org.sonatype.plugins</groupId>
                <artifactId>nexus-staging-maven-plugin</artifactId>
                <version>1.6.7</version>
                <extensions>true</extensions>
                <configuration>
                    <serverId>ossrh</serverId>
                    <nexusUrl>https://oss.sonatype.org/</nexusUrl>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-gpg-plugin</artifactId>
                <version>1.5</version>
                <executions>
                    <execution>
                        <id>sign-artifacts</id>

                        <goals>
                            <goal>sign</goal>
                        </goals>
                        <configuration>
                            <!-- This is necessary for gpg to not try to use the pinentry programs -->
                            <gpgArguments>
                                <arg>--pinentry-mode</arg>
                                <arg>loopback</arg>
                            </gpgArguments>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

Can you please someone help what's wrong with my configuration? Why I am getting the no default secret key: No secret key error?

I have referred this issue but still no luck

Answer 1

When I try to list the secrets it was not showing my secrets gpg --list-secret.

Actually, When I try to list keys using gpg --list-keys it was showing the values. I have assumed the ASC file is imported fine without any issue. But actually, it's not imported the ASC file properly, I missed one step entering the password while importing the ASC file. I got to know by executing gpg --list-secret command.

When you execute the gpg --list-secret & gpg --list-keys command it should show values then only the ASC file is imported correctly.
