I was trying to upload my first api to the maven central but I continue getting this error. I haven't been able to solve it. I am running mvn clean deploy I have read that running mvn clean deploy -Dgpg.skip=true could work but it doesn't. I also have read this threads: stackoverflow github but it doesn't work Here is the error

In some cases if you are using gpg plugin to sign your artifacts you might get the following error and the build will fail.

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-gpg-plugin:1.5:sign (sign-artifacts) on project testng-parser: Exit code: 2

If you get the above error there are few ways to skip artifact signing and carryout your build.

Method 1 : Editing your POM You can disable the gbp plugin from the POM or skip the signing of artifacts. Refer the following.

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>maven-gpg-plugin</artifactId>
    <configuration>
        <skip>true</skip>
    </configuration>
</plugin>

Method 2 : Disabling at runtime You can also disable gpg signing at runtime by running the mvn build with following parameter.

mvn clean install -Dgpg.skip

Or as

mvn clean install -Dgpg.skip=true
