gpg: signing failed: Inappropriate ioctl for device

[hengboy]

I encountered a problem like the title.

name: Deploy the SNAPSHOT version to Maven Center

# Controls when the action will run. Triggers the workflow on push or pull request
# events but only for the master branch

If remove Configure GPG Key step，logs：

Hello @hengboy ,
As stated in #43 and #91, all you have to do to solve the ioctl issue is to add this configuration to Maven GPG plugin in your POM.
Also, you don't need your 'Configure GPG Key' step since this action now deals with it.

[bjansen]

Link is broken, FTR here's the piece of configuration to add to the Maven GPG plugin:

            <configuration>
              <!-- Prevent gpg from using pinentry programs -->
              <gpgArguments>
                <arg>--pinentry-mode</arg>
                <arg>loopback</arg>
              </gpgArguments>
            </configuration>

Hello, everyone. I'm closing this issue, because documentation was updated in terms of this pull request. If you have any concerns feel free to reopen the issue.
Thanks @bissim @bjansen for help with providing solution and related links.

My noggin can't get this to work for one of my project, I have added the config above and my gpg plugin in the pom looks like this:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-gpg-plugin</artifactId>
            <executions>
                <execution>
                    <id>sign-artifacts</id>
                    <phase>verify</phase>
                    <goals>
                        <goal>sign</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <gpgArguments>
                    <arg>--pinentry-mode</arg>
                    <arg>loopback</arg>
                </gpgArguments>
            </configuration>
        </plugin>

And my gpg workflow step like this:

steps:    
- uses: actions/checkout@v2
- name: Set up Repository
  uses: actions/setup-java@v1
  with:
    java-version: 15
    server-id: ossrh
    server-username: MAVEN_USERNAME
    server-password: MAVEN_PASSWORD
    gpg-private-key: GPG_PRIVATE_KEY
    gpg-passphrase: GPG_PASSPHRASE
  env:
    MAVEN_USERNAME: ${{ secrets.OSSRH_USERNAME }}
    MAVEN_PASSWORD: ${{ secrets.OSSRH_TOKEN }}
    GPG_PRIVATE_KEY: ${{ secrets.GPG_PRIVATE_KEY }}
    GPG_PASSPHRASE: ${{ secrets.GPG_PASSPHRASE }}

GPG_PRIVATE_KEY I exported with gpg --armor --export-secret-keys
All I ever get is "Error: The process '/usr/bin/gpg' failed with exit code 2" no matter how I twist and turn this

@Stromner

Did you try not using an env variable for the GPG_PRIVATE_KEY ?
Like so :

- uses: actions/checkout@v2
- name: Set up Repository
  uses: actions/setup-java@v1
  with:
    java-version: 15
    server-id: ossrh
    server-username: MAVEN_USERNAME
    server-password: MAVEN_PASSWORD
    gpg-private-key: ${{ secrets.GPG_PRIVATE_KEY }}
    gpg-passphrase: GPG_PASSPHRASE
  env:
    MAVEN_USERNAME: ${{ secrets.OSSRH_USERNAME }}
    MAVEN_PASSWORD: ${{ secrets.OSSRH_TOKEN }}
    GPG_PASSPHRASE: ${{ secrets.GPG_PASSPHRASE }}

[Stromner]

Ah thanks! That did the work :)

This is working
