Git Ignores and Maven targets

Question

Anyone know if it is possible to ignore all the instances of a particular directory in a file structure managed by git.

I'm looking to exclude all the 'target' folders in a maven project with a number of submodules. I know I can explicitly exclude each of them in a top level .gitignore, but I'd really like to be able to specify a pattern like **/target/* there to have it automatically ignore the instance in sub directories?

Is this possible?

With what configuration are you making this work? */.settings/* would only ignore 'xxx/.settings/*', not '.settings/*' or 'xxx/yyy/.settings/*': the ignore patterns do not seem to be applied recursively.

The .gitignore file in the root directory does apply to all subdirectories. Mine looks like this:

.classpath
.project
.settings/
target/

This is in a multi-module maven project. All the submodules are imported as individual eclipse projects using m2eclipse. I have no further .gitignore files. Indeed, if you look in the gitignore man page:

Patterns read from a .gitignore file in the same directory as the path, or in any parent directory…

So this should work for you.

That is a better answer than '*/target/*'. It does exclude a directory wherever it is located in the tree of directories. But it would not work for files (see http://stackoverflow.com/questions/971465/git-ignore-certain-files-contained-in-specific-folders ) – VonC Jun 15 '09 at 12:04

if you continue reading it says "These patterns match relative to the location of the .gitignore file." Your answear is wrong... – user1387219 Feb 26 '16 at 13:32

I use this approach and use "target/" to ignore all maven build folders, however be careful that you risk to ignore code that is located in packages containing a "target" folder in their path. (In a project with the following classes: `src/main/java/org/example/game/archery/bow/LongBow.java` and `src/main/java/org/example/game/archery/target/Target.java`, your would find nothing to hit with your LongBow with such .gitignore configuration :-) ) – Cristiano Costantini Jan 25 '17 at 15:17

It is possible to use patterns in a .gitignore file. See the gitignore man page. The pattern */target/* should ignore any directory named target and anything under it. Or you may try */target/** to ignore everything under target.

For multi-module projects you may want to use _**/target/_, but be careful not to exclude legitimate "target" directories in the sources – Bogdan Mar 20 '15 at 15:46

`/target/**` works in `\.git\info\exclude` file a well. – Abhijeet Dec 14 '15 at 03:38
Just tried to commit a java project with "target" subpackage in one of it's modules. :( – okutane Mar 14 '17 at 05:47

As already pointed out in comments by Abhijeet you can just add line like:

/target/**

to exclude file in \.git\info\ folder.

Then if you want to get rid of that target folder in your remote repo you will need to first manually delete this folder from your local repository, commit and then push it. Thats because git will show you content of a target folder as modified at first.
