In Git, every line of the file .gitignore is a regular expression that describes files that should be ignored. However, one can also add lines that state which files not to ignore.

Example:

The following example shows a configuration that ignores everything in a particular directory (./tmp) but explicitly states that PDF files in ./tmp should not be ignored:

# Ignore everything in ./tmp ...
/tmp/*

# ... but do not ignore PDF files in ./tmp
!/tmp/*.pdf

Maven-managed Eclipse projects generate appropriate project settings (classpath, build path, etc.) from the pom.xml. The following files need to be ignored in a Maven Eclipse project:

.settings
.project
.classpath
target/

As a shorthand, the following Bash command adds these lines to your .gitignore. It does not matter if your .gitignore is located in the project directory or in any parent of it.

echo “.settings
.project
.classpath
target/” >> .gitignore
