jung2's Introduction
Quick intro to building Jung2 jars with maven2 Ensure that you have a JDK of at least version 1.5. Ensure that your JAVA_HOME variable is set to the location of the JDK. On a Windows platform, you may have a separate JRE (Java Runtime Environment) and JDK (Java Development Kit). The JRE has no capability to compile Java source files, so you must have a JDK installed. If your JAVA_HOME variable is set to the location of the JRE, and not the location of the JDK, you will be unable to compile. *********** Get Maven ************* Download and install maven2 from maven.apache.org http://maven.apache.org/download.html At time of writing, the latest version was maven-2.2.1 Install the downloaded maven2 (there are installation instructions here: http://maven.apache.org/download.html#Installation) Follow the installation instructions and confirm a successful installation by typing 'mvn --version' in a command terminal window. ********** Get Jung2 ******************* Get the jung2 code from CVS: if you are a developer, do this: export CVS_RSH=ssh cvs -z3 -d:ext:[email protected]:/cvsroot/jung co -P jung2 if you are a user, do this: cvs -z3 -d:pserver:[email protected]:/cvsroot/jung co -P jung2 (*** see separate instructions at the end of this file for those unable to use CVS from a command-line console **) ********** Build Jung2 ********************** cd jung2 mvn install This should build the sub-projects and run unit tests. During the build process, maven downloads code it needs from maven repositories. The code is cached in your local repository that maven creates in your home directory ($HOME/.m2/repository). If the download of something is interrupted, the build may fail. If so, just run it again (and again) and it should eventually succeed. Once all the files are cached in your local maven repository, the build process will be faster. *********** Prepare Jung2 for Eclipse ********************** To prepare jung2 for eclipse, run the following maven command: mvn eclipse:m2eclipse which will generate the .classpath and .project files for eclipse. To load jung2 in eclipse, use File -> Import -> General -> Maven Projects and set the Root Directory to your jung2 directory. You should be able to import all of the sub-projects, plus there sill be a jung2 project containing the root pom.xml file Because you previously ran mvn eclipse:m2eclipse at the jung2 directory level, then the projects will already reference the other projects they depend on (instead of the jar from those projects). ************* Run some Jung2 demos ******************************************* Once you have built everything (preceding instructions), here is a straightforward way to run some demos from the command line: (NOTE: you may need to change the version part of the jar names below. It could be jung-samples-2.0-alpha2-SHAPSHOT.jar for example. Look at the actual jar file names to see.) cd jung2/jung-samples/target tar xvf jung-samples-2.0-dependencies.tar java -cp jung-samples-2.0.jar samples.graph.VertexImageShaperDemo java -cp jung-samples-2.0.jar samples.graph.SatelliteViewDemo java -cp jung-samples-2.0.jar samples.graph.ShowLayouts The jung-samples-dependencies.tar file contains all of the jar dependencies for the jung-samples project. It was created as part of the maven build process. (*** Special cvs checkout instructions using eclipse ***) If you are unable to use cvs from the command prompt, you may check out jung2 using eclipse. Create a new workspace that you will be using only to check out the project. You will not be using this workspace to work on the project. Let's call the new workspace $HOME/checkout_base. From that workspace, use eclipse to check out jung2 from cvs. Next, open a command prompt console and change directory to the newly created $HOME/checkout_base/jung2. Execute this command: mvn eclipse:m2eclipse That will build the eclipse artifacts Next, change eclipse to point to a different workspace, one that you will actually be working in. Use the above instructions to import the jung2 subprojects from $HOME/checkout_base/jung2 into your real workspace. (*** end special eclipse cvs instructions ***)
