HANA Express - Web IDE - Git clone error - cannot open git-upload-pack

[Former Member]

Hi,

I'm following OpenSAP development course manual for HANA 2.0 and folloow the exercises.

When in Web IDE, I go to File > Git > Clone repository and input the url of the template files for the course, which is: https://github.com/SAP/com.sap.openSAP.hana5.example

After clicking Ok, I'm getting an error:

Clone request failed

https://github.com/SAP/com.sap.openSAP.hana5.example: cannot open git-upload-pack

Can anyone direct me towards a correct solution? The course itself is already over, so I can't ask there. Thomas Jung (one of the teachers) mentions that I can just import it as a .zip file from Github, but I want to have a fully working connection to repository.
Thanks

I'm running into this same problem of "cannot open git-upload-pack". I feel my setup is very vanilla for Web IDE where I attempted this both from a trial version and from a full SAP Cloud account I am getting this error to connect to the SAP corporate GitHub. If there are certificate installs needed, can someone provide a reference for this? My web searches haven't been successful.

Thanks,

Wes

I'm having the same problem. Just started using HANA Express and going through the course. Is there a solution out there?

Hi colleagues,

To fix the issue you need to generate and save locally a token in Git settings for your user: https://github.wdf.sap.corp/settings/tokens

After that in WebIDE you need to choose Use Token Authentication option and paste the token. Please be advised, you will not be able to see the token in future, so please save it locally.

Hello Annie,

the error "cannot open git-upload-pack" can be caused by lots of different problems. The error message is more like a symptom not like a cause of the actual error. So it's hard to guess whats the actual error.

In other eclipse environments you get a full stack trace like the following which is much better for analysis

In this example which i just copied from https://www.eclipse.org/forums/index.php/t/1065782/ you see there is a inner exception which describes the error much better.

So the question is how can we get this underlying exception?

If we just try every possible cause we will need a lot of time 🙂
