If you need to access subversion from outside a proxy, you need to edit ~/.subversion/servers and add this:

[groups]
mySubversionGroup = *.some.domain
[mySubversionGroup]
http-proxy-host = my.proxy.server
http-proxy-port = 8080

Since Intellij 9.0.3 you now also need to set this information in the svn settings.

I’ve had to google this so many times I thought I would post it.

svn propedit svn:ignore ./some_path

You need this if you want to ignore more than one pattern.
Will open a text editor where you can add multiple entries.

You can also do:

svn propset svn:ignore -F file_to_ignore ./some_path

The -F means ignore a file.

for example:

For directory target

svn propset svn:ignore target .

ignores the target directory in the current dir.

You have to remember to commit the directory you have just set the property on:

svn ci -m "Setting the ignore property to ignore target directory" -N .

The -N means non-recursive so just commit the current directory.

This can happen if at some point you check out without specifying the full path.

eg:

svn co svnserver/myproject/trunk ~/myproject

rather than

svn co svnserver/myproject/trunk ~/myproject/trunk
