无法执行目标org.apache.maven.plugins:maven-gpg-plugin

Question

这个错误快把我逼疯了。有人能帮帮我吗？我确实安装了gpg，它也在PATH中。是什么导致了这个错误！

我在linux和windows上的jenkins 1.5，maven 3.0.3上运行此作业(两者都显示相同的错误)

Answer 1

如果您不需要对工件进行签名，则可以禁用或跳过父pom中定义的gpg插件的执行。

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

或者使用gpg.skip=true (参见Maven GPG Plugin)运行构建

如果您需要对工件进行签名，您应该检查父pom中gpg-plugin的配置，或者覆盖您的pom中的配置。也许父pom中的一些设置与您的系统环境不匹配，但从错误消息中很难判断。

Answer 2

这个问题发生在我从Ubuntu 16升级到Ubuntu 18.04 LTS之后。

gpg --version
gpg (GnuPG) 2.2.4

首先，我在一个非jenkins环境中检查了相同的项目

mvn install

我得到了这个信息

gpg: signing failed: Inappropriate ioctl for device

这给我指出了

https://github.com/keybase/keybase-issues/issues/2798

和

https://tutorials.technology/solved_errors/21-gpg-signing-failed-Inappropriate-ioctl-for-device.html

export GPG_TTY=$(tty)

是推荐的治疗方法。我已经将它添加到我的.profile中，并重新启动了

mvn install 

测试。这一次，我被要求通过终端输入OpenPGP密钥的密码。在没有输入密钥的情况下，通过命令行的第二次运行成功。

然后，我停止并重新启动jenkins，并再次尝试失败的作业。这一次它起作用了。

不幸的是，它仍然不能在启动xsession的jenkins jobx中工作。http://maven.apache.org/plugins/maven-gpg-plugin/usage.html明确指出，您可以将gpg.passphrase放在settings.xml中，我已经有效地使用了很长一段时间。我知道我不知道如何恢复这个行为，我只能提供上面的变通方法。

Answer 3

这意味着您需要一个密钥来对jars进行签名。只需遵循this流程直到最后一步(您不需要以前复制到github )

下面是一个总结：

1. 打开Git Bash
2. gpg --gen-key #使用默认值，密钥大小为4096
3. gpg--

-secret-keys--keyid--format LONG

1. gpg --armor --EXPORT%从上面导出%
