How do I stop Subversive from setting svn:mime-type to text/plain on initial commit?
My Java code is being checked into my repository with the svn:mime-type property set as text/plain, and as a result my web-based SVN viewer (trac) isn't syntax highlighting.
I should add I'm running Eclipse 3.5 and the most recent version of Subversive with the SVNKit 1.3.0 (for SVN 1.6) adapter.
For those finding this question, this issue no longer exists as it was resolved through an option in the preferences section of Subversive.
You'll need to actually setup the mime types yourself in "Window > Preferences> Team > SVN > Properties Configuration > Automatic Properties"
For file type *.java for example, set it to: svn:mime-type=text/x-java
If your project already got messed by subversive, cd to project root and run the following commands
find . -name "*.java" -exec svn propset svn:mime-type 'text/x-java' {} \;
find . -name "*.xml" -exec svn propset svn:mime-type 'text/xml' {} \;
We just ran into this as well. FYI all, I've posted https://bugs.eclipse.org/bugs/show_bug.cgi?id=322772
By default, Subversion only sets svn:mime-type to application/octet-stream when the file is binary (and you didn't explictly assign any other value). See Automatic Property Setting for reference. So this feature is courtesy of Subversive.
I'm afraid I'm not a Subversive user, but I found in Google a reference to a menu in "Window > Preferences> Team > SVN > Properties Configuration > Automatic Properties" where it seems you can remove unwanted associations.
The reported bug by vorburger (https://bugs.eclipse.org/bugs/show_bug.cgi?id=322772) has been fixed. There is an option called 'Set text MIME type for all non-binary files' under "Window > Preferences> Team > SVN > Properties Configuration > Automatic Properties" which needs to be unchecked to prevent Subversive to add the S/MIME-Type to newly added resources.
