Maven
These are useful links to get started with Maven.
Apache Maven Project http://mevenide.codehaus.org/m2-site/
Download & Install
Make sure you get Maven 2.x (not 1.x).
http://maven.apache.org/download.html
Installation instructions (from the site linked above):
Windows 2000/XP
Unzip maven-2.0.7-bin.zip to the directory you wish to install Maven 2.0.7. These instructions assume you chose C:\Program Files\Apache Software Foundation\maven-2.0.7 Add the bin directory to your path, by opening up the system properties (WinKey + Pause), selecting the "Advanced" tab, and the "Environment Variables" button, then editing the PATH variable in the user variables. eg. "C:\Program Files\Apache Software Foundation\maven-2.0.7\bin";%PATH% In the same dialog, make sure that JAVA_HOME is set to the location of your JDK, eg. C:\Program Files\Java\jdk1.5.0_02 Run mvn --version to verify that it is correctly installed.
Unix-based Operating Systems (Linux, Solaris and Mac OS X)
Extract the distribution archive to the directory you wish to install Maven 2.0.7. These instructions assume you chose /usr/local/maven-2.0.7 . The directory maven-2.0.7 will be created from the archive. Add the bin directory to your path, eg. export PATH=/usr/local/maven-2.0.7/bin:$PATH Make sure that JAVA_HOME is set to the location of your JDK, eg. export JAVA_HOME=/usr/java/jdk1.5.0_02 Run mvn --version to verify that it is correctly installed.
Quick Tutorial
Maven Plugins for IDE's
Eclipse
There are two plugins available, use either url for a "New Remote Site" in eclipse "Help->Software Updates": * http://m2eclipse.codehaus.org * http://m2eclipse.sonatype.org/update With a good [http://java.dzone.com/blogs/mrjohnsmart/2008/03/19/new-maveneclipse-integration-p article] on how to use it.
If your maven repository is not in your user home directory under .m2 you need to tell Eclipse where it is (and it's worth double checking it's set it up right either way. See [http://maven.apache.org/guides/mini/guide-ide-eclipse.html#Maven%202%20repository here]
for instructions
Right-click on your project, choose Maven2 and 'enable' to use the plugin on a per-project basis. This will set up your local Maven repository (under the /<users.home>/.m2 directory) as a library in Eclipse.
Note: If you have more than one pom file in a project you must have a parent pom in order for the maven plugin to recognize all of the poms. You can create a basic pom then add it as a parent to all of the other pom files (you do not have to add them as modules to your parent, it's just a little simpler sometimes).
- You can run maven commands by right-clicking on any pom file (assuming you've correctly parented them) and choosing the commands to run. Generally to run a full compile and all tests I run "clean package". If you run into problems running within Eclipse you can run the same commands from command line, often you will get easier to understand errors that way as well.
In your eclipse project you should see a library now called "Maven Dependencies" or something similar. If you expand it all of your libraries listed as dependencies in the pom files should be listed.
Cytoscape, Eclipse & Maven
Each time you update run "maven install" from your top level cytoscape directory. This installs the poms for the corelib modules and any other dependencies within the project to your local repository. If you don't do this Eclipse will continue to mark the parts of your code that it can't find with red and it will be unable to compile. This is temporary as various layers and modules are being added and moved around.
If you continue to have problems with updates not being recognized go to your .m2/repository directory. Delete the directory org/cytoscape and re-run "maven install". If version numbers are not updated in pom files or if versions are not marked as "SNAPSHOT" then the latest updates may not correctly install, removing this directory forces a fresh install regardless.
IntelliJ
The newest version of IDEA comes ready to use maven, but here are the plugins if you need to load them:
IntelliJ plugins:
This is easier to use than maven+eclipse but it also requires that if you have multiple poms a parent is set up.
