I have a saved project in Subversion repository and compiles it with Jenkins. When I run the build, Jenkins pulls project into workspace directory. I need commit one changed
Please have a look to this answer: Jenkins svn commit post-build
It should be possible to commit with a new build step (or a post build step).
But be careful with the SVN layout of the Jenkins workspace. The subversion plugin is using the SVNKit to deal with the SVN commands. Your workspace maybe use the SVN layout 1.6.
If the SVN client is more recent on your machine, your SVN commit will fail with the following error: org.apache.subversion.javahl.ClientException: The working copy needs to be upgraded svn: Working copy 'C:.... is too old (format 10, created by Subversion 1.6)
