Using org.lcsim with Eclipse

Instead of NetBeans, you can also use the Eclipse IDE to build org.lcsim and write your applications.

Download Eclipse: http://eclipse.org/downloads/index.php

Source Path

You may have to change the source path of the project, otherwise Java may be inclined to look for packages src.org.lcsim.* instead of org.lcsim.*. This can be done by right-clicking on the project and selecting Properties->Java Build Path. The src/ folder should be selected as the only source folder.

External Dependencies

When working with external libraries such as org.lcsim, you have to add those libraries to the build path. This can be done by right-clicking on the project and selecting "Properties->Java Build Path->External Libraries". Select add external jar and choose the Jars from your JAS3 installation path. They are in the subdirectories extensions and libs as well as in $HOME/.JAS3/extensions

LCSim with Europa

First, install org.lcsim using command-line Maven 2.

  1. Checkout GeomConverter and org.lcsim.
  2. Build GeomConverter, first, and then org.lcsim with the mvn command. (This ensures that all the lcsim dependencies are built/downloaded before we start messing with Eclipse.)
  3. If either build complains about missing lcsim-base, then checkout that project from SLAC CVS and build it, too.

Now, setup Eclipse with Maven 2.

  1. Get an appropriate Eclipse Europa build.
  2. Unpack and install the Eclipse build and open Eclipse by double-clicking on its icon. (In OSX, this is eclipse.app.)
  3. Go to Help -> Software Updates -> Look for new features to install. Click Next.
  4. Click New Remote Site.
  5. Put "q4e" in the name field and use this URL: 
    http://q4e.googlecode.com/svn/trunk/updatesite/
    .
  6. Click through the rest of the q4e install and agree with all the EULAs.

Finally, create a new project in Eclipse for org.lcsim.

  1. Select File -> New -> Java Project.
  2. Name the project "LCSim".
  3. Select create project from existing source and select your org.lcsim directory.
  4. Hit Next a and then Finish.
  5. I usually use command-line Maven 2 here: 
    mvn eclipse:eclipse
  6. You can also try right-clicking on the LCSim project and selecting Maven 2 -> Execute Goal. In the command box, put eclipse:eclipse and ok.
  7. Right-click on the LCSim project in the Project Explorer window and click Refresh.
  8. Select Maven 2 -> Reload Maven and let Eclipse think.
  9. Now select Maven 2 -> Enable Maven dependency management.

If the last step executes successfully, then all the nasty red errors should go away and command completion should work.

You can quickly build Maven 2 projects from within eclipse by executing the install goal with maven.test.skip set to true. This should rebuild the JAR files if you have made changes.
