Preparing a gitignore File

This page describes a feature that is currently available using Mule Studio (December 2013) or newer. Download and launch the latest version of Anypoint Studio to take advantage of this feature.

As a part of a team of developers, you may be using a source code management (SCM) tool such as git to keep track of changes in an application. Studio supports the use of git by presenting an option to prepare a standard ` gitignore ` file for a new Mule Project.

Prerequisites

This document assumes familiarity with git as a software version control system, and that you are using Anypoint Studio to build a new application that you intend to manage using git.

Configuring a gitignore File

A project’s ` gitignore ` file contains a list of files and folders that git should ignore when tracking a project. Because all Studio projects contain a set of files that git should not include in its version control, you can create a gitignore file when creating a new Mule Project in Studio.

  1. Create a new Mule Project (File > New > Mule Project).

  2. In the first pane of the New Mule Project wizard (see image below), check Create a default .gitignore file:

A dialog box with settings to create a Mule project, including the option to create a default gitignore file

  1. Click Finish to save and open your new project.

Studio stores the gitignore file as a hidden file in the project’s root directory. To view the contents of the file, change the settings of your operating system to display hidden files.

gitignore File Contents

A gitignore file generally includes several files and folders that are commonly part of Java and Eclipse projects. A gitignore file prepared in Studio contains a few more Studio-specific elements (see table below).

Studio-specific Ignored File or Folder Reason 
.studio/

A hidden folder, it contains information that is irrelevant for synchronizing such as cached metadata files that git does not need to track.

 
flows/

Including this folder in gitignore ensures that git does not track visual changes in the canvas which have do not affect the working of the flow.

 
target/

Including this folder in gitignore ensures that git does not track the elements Studio uses to construct the target folder upon build.
