在GitHub上创建Maven存储库

我们可以在github创建Maven存储库，这样可以在github托管java的依赖构件。如果有工程需要依赖，也可以通过maven方便的下载依赖。也许我们将Maven存储库托管在GitHub上有许多理由，包括许可问题、隐私和商业托管成本。无论您为什么选择托管基于GitHub的Maven存储库，设置一个存储库都很容易。具体设置步骤如下:

1.创建仓库

首先,在你的github上创建一个maven-repo,创建一个README.md，如清单1.1所示（不然后需mvn clean deploy 会报409错误）

清单1.1

2.修改maven的setting.xml文件

<server>
	<id>github</id>
	<username>github登陆名</username>
	<password>github登陆密码</password>
</server>

3.配置本地工程功的pom.xml文件

3.1设置一个从中提交文件的基本目录。

首先创建一个临时目录，并将它放在项目的 target 目录中，如清单3.1所示。对于本示例，我将该目录命名为 repo-stage。接下来，因为您想将此插件关联到 deploy 阶段，所以必须在 maven-deploy-plugin 的 中指定存储库位置，如清单 3.1 中的代码片段展示了如何指定存储库位置。

<plugin>

    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.6.1</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
    </configuration>
</plugin>

3.2 配置site-maven-plugin并将它关联到 deploy 阶段。

请向该插件传递之前创建的 GitHub 服务器的 id，或者配置属性（github）。还需要向它传递存储库名称和所有者、您将项目工件提交到的分支，以及针对该提交的注释。您还需要关闭 Jekyll，让它不会认为自己需要生成 GitHub 页面。存储库名称是 dependency（如果该分支不存在，GitHub 将创建它）。配置如清单3.2

5. 过程执行的问题

5.1.[ERROR] Failed to execute goal com.github.github:site-maven-plugin:0.12:site (de fault) on project maven-sampler: Error creating blob: Git Repository is empty. ( 409) -> [Help 1]

  • 解决方法：在github上创建的仓库里创建README.md文件。

5.2 [ERROR] Failed to execute goal com.github.github:site-maven-plugin:0.11:site (default) on project alta-maven-plugin: Error creating commit: Invalid request.
[ERROR]
[ERROR] nil is not a string.
[ERROR] nil is not a string. (422)
[ERROR] -> [Help 1]

  • 解决的方法：在github的个人设置中，设置好自己的姓名 。这个环节很重要，若不设置姓名，会出现一些一些意想不到的错误，

5.3 Error creating blob: Received fatal alert: protocol_version -> [Help 1]

  • 解决的方法：使用jdk1.8 或修改jdk1.7的协议版本为高版本
