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

Question

这个错误让我发疯.有人可以帮帮我吗？我确实安装了gpg,它也在PATH中.是什么导致了这个错误!

我在jenkins 1.5上运行这个工作,在linux和windows上运行maven 3.0.3(都显示相同的错误)

Answer 1

如果您不需要对工件进行签名,则可以禁用或跳过在父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>

或运行构建gpg.skip=true(参见Maven GPG插件)

如果您需要对工件进行签名,则应检查父pom中gpg-plugin的配置或覆盖pom中的配置.也许父pom中的某些设置与您的系统环境不匹配,但很难从错误消息中说出来.

Answer 2

这意味着您需要有密钥来签署罐子。按照这个过程直到最后一步就可以了（显然不需要复制到github）

这里总结一下：

1. 打开 Git Bash
2. gpg --gen-key#使用默认值 4096 作为密钥大小
3. gpg --list-secret-keys --keyid-format LONG
4. （选修的）gpg --armor --export %the key from above%

Answer 3

在夜间 jenkins 构建中从 Ubuntu 16 升级到 Ubuntu 18.04 LTS 后，我遇到了这个问题。

gpg --version
gpg (GnuPG) 2.2.4

首先，我在非 jenkins 环境中检查了同一个项目

mvn install

我收到了消息

gpg: signing failed: Inappropriate ioctl for device

这指向我

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

和

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

export GPG_TTY=$(tty)

是那里推荐的补救措施。我已将此添加到我的 .profile 并重新启动

mvn install 

测试。这次我被要求通过终端输入 OpenPGP 密钥的密码。通过命令行的第二次运行成功，无需输入密钥。

然后我停止并重新启动 jenkins 并再次尝试失败的工作。这次成功了。

不幸的是，它在启动 xsession 的 jenkins jobx 中仍然不起作用。 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时间。知道我不知道如何恢复这种行为，我只能提供上述解决方法。
