Introduction

This document is intended to set up the Maven committer environment.

Source File Encoding

When editing source files, make sure you use the right file encoding. For the Maven project, UTF-8 has been chosen as the default file encoding. UTF-8 is an encoding scheme for the Unicode character set and as such allows to encode all characters that Java can handle. The source files should not contain the byte order mark (BOM). There can be exceptions to this general rule, e.g. properties files are usually encoded using ISO-8859-1 as per the JRE API, so please keep this in mind, too.

Subversion Configuration

Before committing files in subversion repository, you need to read the Committer Subversion Access document and you must set your svn client with this properties file: svn-eol-style.txt

Maven Code Style

The following sections show how to set up the code style for Maven in IDEA and Eclipse. It is strongly preferred that patches use this style before they are supplied.

IntelliJ IDEA 4.5+

Download maven-idea-codestyle.xml and copy it to ~~/Library/Preferences/IntelliJIdeaxx/codestyles then restart IDEA (with xx your idea version). On Windows, try C:\Documents and Settings\<username>\.IntelliJIDEA\config\codestyles

After this, restart IDEA and open the settings to select the new code style.

Eclipse 3.2+

Download maven-eclipse-codestyle.xml.

After this, select Window > Preferences, and open up the configuration for Java > Code Style > Code Formatter. Click on the button labeled Import... and select the file you downloaded. Give the style a name, and click OK.

Useful software

The Maven Team uses several software. Here is a partial list:

  • Cygwin: collection of free software tools to allow various versions of Microsoft Windows to act somewhat like a Unix system
  • GnuPG: GNU Privacy Guard.
