Maven - 生成JAR GPG签名

标签: java maven jar gnupg sonatype

我是Maven的新手并将内容上传到Sonatype,所以错误可能很明显,但它隐藏得很好。我试图上传工件。

为此,我运行以下命令

mvn clean assembly:single -s settings.xml assembly:single javadoc:jar source:jar gpg:sign -Dgpg.passphrase=myPassphrase install deploy

然而,这导致Nexus在验证JAR文件时失败,因为上传中没有包含asc签名文件 - 这是真的,但我不明白为什么。此外,还有.xml文件和.zip,.tar.gz和.tar.bz2文件的签名。我还应该为罐子生成的ascs指定什么?

下面显示了我的settings.xml和pom.xml文件:

的settings.xml:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <servers>
    <server>
      <id>sonatype</id>
      <username>myUsername</username>
      <password>myPassword</password>
    </server>
  </servers>

</settings>

的pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

为了将jar上传到maven资源库,您需要使用必须在给定密钥服务器上提供的公钥对其进行签名。点击此处detailed instructions,此blog post也很有帮助。

最重要的步骤是创建一个密钥并将其上传到密钥服务器(详见上面的链接)。

然后编辑settings.xml以使PGP可用于Maven:

<profiles>
      <profile>
          <id>gpg</id>
          <properties>
              <gpg.passphrase>your passphrase</gpg.passphrase>
              <gpg.keyname>your pgp key</gpg.keyname>
          </properties>
      </profile>
  </profiles>

然后在pom.xml中添加它以便对jar进行签名:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-gpg-plugin</artifactId>
    <version>1.4</version>
    <executions>
        <execution>
            <id>sign-artifacts</id>
            <phase>verify</phase>
            <goals>
                <goal>sign</goal>
            </goals>
        </execution>
    </executions>
  </plugin>  

这是working pom.xml的一个例子。
