I need to use Talend Open Studio with a SVN. What is the folder that I should put in the repository?
Putting a TOS workspace under SVN is strongly discouraged, as CSV/SVN as file-based by nature while TOS workspace is directory-based. The probability that you incur in workspace corruption are very high.
However I achieved good results putting in under git, instead (have a look here for an idea). I must say it's not elegant and putting the entire workspace under version control is a tremendous waste of space (you will commit compiled files, logs, history, temp...), but it's the only safe solution for your metadata integrity.
