通过ANT克隆GIT存储库

Question

I am working over GIT cloning with help on ANT.I am using the below code for it :

<target name ="deploy">

 <sshexec host="ssh://user@rep_location/project_name.git"
    username="username"
    password=""
    passphrase="passphrase"
    trust="true"
    command="git clone ssh://user@rep_location/project_name.git  D:/dest"/
    />

</target>

The location " D:/dest " is the required folder where I want my repository cloned. But it throws error as unknown host exception .

I tried few combination with host like ssh://user@rep_location but it also returns server connection timeout.
We require a passphrase to be provided at the time of checkout. This command works fine with GIT BASH .

Answer 1

This should be linked to this "Unknown Host key" classic ssh error: see " com.jcraft.jsch.JSchException: UnknownHostKey ".

The simplest solution remains to do the ssh manually first:

Try to ssh from the command line and accept the public key (the host will be added to ~/.ssh/known_hosts )

Make sure, on Windows, that you have a HOME environment variable defined, in which the JSch used by the sshexec ant task will be able to find %HOME%\\.ssh\\known_hosts file.
That differs from a unix-like git bash session, where $HOME is always defined.

Answer 2

The following error means ANT cannot resolve the hostname:

unknown host exception

You are supplying a git URL as the value of the host parameter:

 <sshexec host="hostwhereIwanttoclonerepository.com"
    username="username"
    passphrase="passphrase"
    trust="true"
    command="git clone ssh://user@rep_location/project_name.git  D:/dest"/
    />

Keep in mind that you are running the git command on a remote machine, the "username" account will require valid SSH credentials to access the git repository host.

Finally, I suspect you're trying to clone the repository locally? In that case you should not be using the sshexec task. I recommend trying the "git-clone" ANT task from jGit . For an example:

• How can I get the latest commit ID of the currently checked out branch in git, using ANT, without having an active git installation?

You may need to also include the jsch jar in order to access an SSH Git URL.

<exec executable="${gitBinPath}">
    <arg value="clone" />
    <arg value="--depth" />
    <arg value="1" /> 
    <arg value="${gitRepositoryURL}" />
    <arg value="${deployDir}" />
</exec>

• gitBinPath: Location to git.exe
• gitRepositoryURL: Git Repository URL

• deployDir: Destination folder
