如何与使用ssh代理的maven进行git克隆？

Question

我想用maven克隆一个存储库，并且身份验证必须使用现有的ssh代理。

我目前的插件配置：

<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>

身份验证失败：

可以使用exec插件来调用git命令。在这种情况下，ssh代理被使用。

<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>
