Ideal process

• Update
• Check that it runs (JUnit tests)
• Commit with a short meaningful comment

svn can also work inside Eclipse.

How to use subversion well:

• Think what to put in svn and what not. It's impossible to remove things forever.
• by default: src should be in svn, target should be svn-ignore
• Always synchronise instead of commit (first see, then act)
• Checkin only a classpath with relative references
• Use commit messages :-)
• check that it compiles and JUnit test run
• use the same code format style
• if you have a conflict: make sure not to overwrite something (mark as merged)

Using SVN from Eclipse - needs a plugin

• Plugin 1: Subclipse (from Tigris, works well with svn)
• preferences > "SVN", choose pure Java (instead of JNI)
• Plugin 2: Subversive (from Polarion)

Using SVN on the command line

Enter into the directory of the Eclipse project and write "svn command". The important commands are:

• svn up: update: download the new files
• svn log: show the revision history
• svn diff: show the difference between our files and the files at the server
• svn ci: commit: upload our changes. It opens an editor, where we can write a short message

To reload maven dependencies:

• Has nothing to do with svn, just call "mvn compile"

Maven and Subversion

Add /target to svn.ingnore

Problems with Subversion

User/pass don't work

You can check out anonimously, but to check in you need:

• your gmail name (at the left of the @)
• a Googlecode password; see in this page. Not the pass from Gmail

If these don't work, check that you're using https://...* as the repository's URI, and not http://...* (you can't check in per HTTP).

If you had started with a http URI in Eclipse and you want to change to a https, you can do the following:

• enter at the directory
• write "svn info" to see the project's URI
• write "svn switch --relocate oldURI newURI". For instance, I wrote that for swecr.core:

• that should work and Subclipse should detect the change

undo committed changes that are long ago
