Putting Xtext projects into Git repositories [message #1230020]

I have recently tried to put an Xtext project into a git repository and didn't have much success. I tried doing this the following way:

1. Select the three generated projects and use Team->Share to put them into a repository.

2. Add all the source folders, the manifest files, and the build.properites and plugin.xml files to the index and commit them. I did not add the src-gen and xtend-gen directories as they are regenerated.

When I tried cloning the repository I got strange build errors and apparently the resulting projects were not set up correctly. I got no generated files even after cleaning the projects and forcing a rebuild.

So, what is the magic invocation necessary to store Xtext projects in a git repository so they can be tracked and shared?

Hi

What about .project and .classpath (and .settings)?

Regards

Wow, quick replies. Smile

I only thought about adding those files that are visible in the package explorer. I will try it again with the .project and .classpath added from the command line.

And, yes, I did try re-running the workflow and nothing got generated. Hopefully it was from these missing files.

I want to confirm that the above approach does seem reasonable to everyone and that I am not just spinning my wheels here. For example, do I need to include the .metadata directory as well?

Hi,

there are guys that check in everything.
others use maven to build.

Hi Mark,

It would be helpful to post the "strange build errors" in the question.

From what you are describing, I suspect that in the cloned repo the projects are missing the src-gen and xtend-gen directories alltogether, which prevents the build.
This happens in your scenario is because git does not store directories, only files.
The fix is to create the said dirs manually (new > folder).
Alternatively, you could add src-gen to git, as it saves you from a mwe regeneration when switching branches (assuming you have several.. )

Cheers
Vlad

Ah, this could have been it as well.

Something we have done in the past on other projects (not using git) was to create an empty text file (usually called 'empty.txt') and placed it in a folder we wanted to use as a place holder. Perhaps this would work as well.

So, the workflow won't automatically recreate the src-gen and xtend-gen folders for me? It does seem to create any subdirectories of these folders when I, for instance, add new xtend files to a new package in src. But the -gen folders already exist, of course, in those cases.

Hi if the classpath is broken the Workflow might Not work (depending how you Start it)

Hi, i suggest you to do the git work through a terminal or shell so that you can control all the files.

You can start with adding all the files under the directories with a customized .gitignore file.

Here is my .gitignore file for Xtext projects:

.settings
tmp
bin
target
generated
generated-sources
src-gen
xtend-gen
model
*.xml_gen

Actually i'm not sure about the .classpath and .project files too.

Hope this can help you.
