如何使用使用ssh-agent的maven克隆克隆？

Question

我想用maven克隆存储库，并且认证必须使用现有的ssh-agent。

我当前插件配置：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-scm-plugin</artifactId> 
    <version>1.9.4</version> 
    <configuration> 
     <providerImplementations> 
       <git>jgit</git> 
     </providerImplementations> 
    </configuration> 
    <dependencies> 
     <dependency> 
       <groupId>org.apache.maven.scm</groupId> 
       <artifactId>maven-scm-provider-jgit</artifactId> 
       <version>1.9.4</version> 
     </dependency> 
    </dependencies> 
    <executions> 
     <execution> 
      <id>clone-github-wiki</id> 
      <goals> 
       <goal>checkout</goal> 
      </goals> 
      <phase>generate-resources</phase> 
      <configuration> 
       <checkoutDirectory>${project.basedir}/target/github-wiki</checkoutDirectory> 
       <connectionType>connection</connectionType> 
       <connectionUrl>scm:git:git@github.com:xyz/abc.wiki.git</connectionUrl> 
      </configuration> 
     </execution> 
    </executions> 
</plugin> 

认证失败：

Exec插件可被用来调用git的命令。在这种情况下，使用ssh代理。

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>exec-maven-plugin</artifactId> 
    <version>1.3.2</version> 
    <executions> 
     <execution> 
      <id>github-wiki-clone</id> 
      <goals> 
       <goal>exec</goal> 
      </goals> 
      <phase>generate-resources</phase> 
      <configuration> 
       <executable>git</executable> 
       <arguments> 
        <argument>clone</argument> 
        <argument>-b</argument> 
        <argument>master</argument> 
        <argument>git@github.com:abc/xyz.wiki.git</argument> 
        <argument>target/github-wiki</argument> 
       </arguments> 
      </configuration> 
     </execution> 
    </executions> 
</plugin>
