SVN ignore like .gitignore

In Git, if I have a project with lots of projects inside, let's suppose, a lot of Java projects, I can just create a .gitignore file in the root and it will "be respected" in the entire repository.

How can I do this for an SVN project?

For example, how can I make an "svn ignore" setup (via cmd line) for a .gitignore like the following?

*.class
*.jar
*.war
*.ear
target/
.classpath
.settings/
.project
.metadata
bin/

The most important part of the question: How can I make it work to new folders inside the root? Example:

I ran svn propset svn:ignore "*.class" . -R in my root and commit. Ok:

root
- folder1/
-- *.class (ignored)
-- other files (ok)
- folder2/
-- *.class (ignored)
-- other files (ok)

Now, I create folder 3. The previous svn:ignore settings will not apply, right? Is there a way to make it so?

You can use svn:ignore. You generally need to tell SVN to apply special properties to the files:

svn propset svn:ignore "*.jpg" .

(Note the dot at the end of the command.)

For multiple files you can add a newline character.

Type exactly like here with line breaks:

svn propset svn:ignore "file1
file2
file3" dir1

Check that the files are ignored:

svn status --no-ignore

Then commit the code.

And yes, many duplicate questions are already available.

You can refer my favorite svn cheatguide.

You can create a file, svn-ignore.txt, with your ignored files and directories:

*.class
*.jar
*.war
*.ear
 target/
.classpath
.settings/
.project
.metadata
 bin/

Now try the following:

svn propset svn:ignore -RF /root/svn-ignore.txt . [dot for current dir]

-R is for recursive.

This is what I am doing to emulate .svnignore.

Create a wrapper for svn called ~/bin/svn

#!/bin/bash
case "$1" in
commit|status|apply-ignore)
    if test -f .svnignore ; then
        echo "Apply .svnignore: $(/usr/bin/svn propset svn:ignore -F .svnignore .)"
    fi
    ;;
esac
case "$1" in
apply-ignore) ;;
*) exec /usr/bin/svn "$@" ;;
esac

Then add ~/bin to your path before /usr/bin

PATH=~/bin:$PATH ; export PATH

It applies .svnignore on commit and status commands, and can also manually apply using svn apply-ignore.
