For the past few months i have been switching some projects over to git from Subversion. And have been trying to get the hang of all the command line options available. And i will be doing that for a while longer until i get completely comfortable. And for communication to the remote git server i have been using SSH key authentication. Which works smoothly just like it did with Subversion.
But i wanted to check out the GIT support available in Zend Studio 9. And hit a problem pretty quickly. But i will describe that below. First i will create a local clone of my git project.
$ git clone ssh://[somehost]/~/git/project.git
To test if everything is working i do a test commit. If that succeeds if push it out to the remote master.
$ cd project.git
$ touch TEST
$ git commit
$ git push origin master
So that works fine. Now time to see how Zen Studio handles this. To create a project i use the Create from Git option. And select the local checkout i just created. This will read the whole repository configuration. And you are basically done from here. But as i mentioned earlier, i had some difficulties getting things running smoothly. I discovered that when it was time to push changes to the master repository.
When i used the Push to Upstream option. I was greeted by a login panel that seemed to have selected the correct SSH key and user to perform the login. But when i typed the password, it just kept asking for the password. Again and again. Hmm. That sucks! The password was correct. I tried with a newly created key. No luck either. The last thing i tried was updating to a nightly build of Egit found here. But this offered no solution either.
After reading a couple of complaints i found this bug report for the EGit eclipse plugin. The thread contains a solution for the login issue i was having. Gotta love Google!
Apparently the problem has to do with the encryption algorithm used to create the SSH keys. In this case the EGit plugin (which uses Jsch to do the SSH communication) was having problems with AES encrypted keys. And to solve the problem the Jsch library should be replaced with a newer version to make things work again.
So lets download this JSch library and update it manually. The library (JSch v 0.1.46) can be found here.
$ cd ZendStudio9
$ find . -name ‘*jsch*’ -type f
Found it plugins/com.jcraft.jsch_0.1.41.v201101211617.jar. So let’s try to update that.
$ cp plugins/com.jcraft.jsch_0.1.41.v201101211617.jar plugins/com.jcraft.jsch_0.1.41.v201101211617.jar.backup
$ wget http://sourceforge.net/projects/jsch/files/jsch.jar/0.1.46/jsch-0.1.46.jar/download
$ mv jsch-0.1.46.jar plugins/com.jcraft.jsch_0.1.41.v201101211617.jar
After restarting ZS everything worked fine again. Another problem solved! Thanks to the guys who posted in the EGit bug thread. Some good community Karma here! Time for other things. Hope it helps!
