Select 1.6 in the Compiler compliance level: combo box and press Apply. Make sure Java 1.6 appears as an installed JRE and that it is the default JRE for the project.ī) Use the Eclipse Menu: Window -> Preferences -> Java -> Compiler. Select the JDK and Set the Compiler Compliance #Eclipse maven the specified jre installation does not exist installIt is recommended that you install the JDK separately since you may wind up using several versions. ![]() You may install any package since you can add plug-ins later but it is convenient to install the "Eclipse IDE for Java EE Developers" since it already contains most of the plug-ins you may want to use. Install Eclipseĭownload and install Eclipse. So having a top-level Workspaces directory is helpful. #Eclipse maven the specified jre installation does not exist windowsAlso, very long directory structures may be found in Eclipse projects and generally don't cause problems with Eclipse, but may cause problems with other products in Windows XP. Eclipse and the Fedora command-line Maven-based build tools will work with proper set-up but you will have less trouble if you avoid directories with spaces in their names. It is also convenient for you install the JDK outside "Program Files" if you are developing in Microsoft Windows, using a directory with no spaces in the name. Note that a JDK is required for some operations of the M2Eclipse plug-in described below. It is not required that Eclipse be running in the same JDK/JRE version as is being used for development but it is convenient if you use the same JDK/JRE version on the command line as you are using for Eclipse. The Oracle/Sun JDK may be obtained from here for common platforms. Initially, we recommend installing the Sun JDK to get success and then you may explore other options. Eclipse has a very sophisticated structure which supports the installation and use of multiple Java compilers and run time environments. Use of Indigo has substantial advantages since Maven support through m2e plug-in (formerly called M2Eclipse) is fully integrated with Git support (through the EGit plug-in).įedora is only tested with the Sun JDK though others may work well or even be required for a particular operational environments such as specific application servers. Fedora has been built using the last three releases of Eclipse however this article uses Indigo, the latest release, as an example. It contains a significant amount of information about the Fedora Repository and building it from source which is not repeated here. It is important that you read the Installation and Configuration Guide first. This article uses the Fedora Repository service as an example. Like Eclipse, Maven is based on the idea of using "convention over configuration." While Maven is very flexible, it promotes good modularization practices which should make using Eclipse for Fedora easier.įedora development has now moved to Git and the sources are hosted on GitHub. You can build Fedora using Maven from the command line or within Eclipse. Maven helps manage dependencies and makes project information readily available. The current Fedora Repository trunk (Fedora 3.3 and greater) uses Apache Maven for building the source. The options are too numerous for one article so we will describe just a few popular configurations to get you started. You may build the Fedora Repository from the command line and just use Eclipse for editing and debugging. You do not need to build the Fedora Repository from source in Eclipse in order to build your own projects though it may be convenient. Further, Eclipse has now released Indigo that incorporates M2Eclipse with direct support of git.Įclipse is a popular integrated development environment (IDE) which is used by many developers for the Fedora Repository service, clients and other related services. However, a number of other Eclipse configuration instructions are not covered in that article. There is a separate article on Git integration including Maven. ![]() The Subversion-related content of this article is no longer valid.
