LDN - Luminis Developer Network

We use Eclipse for development and we use the compare functionality in Eclipse to process our Luminis customizations for upgrades. When comparing Jar files (like uPortal.jar) eclipse gives you a breakdown of what has changed in each of the files in the archive. This is a great feature, but it would not work for a car or war file. I did a bunch of searching and came up with the following change for comparing Car files structurally.

In the file org.eclipse.jdt.ui_3.2.1.r321_v20060907.jar (or what ever version of org.eclipse.jdt.ui you have) there is a plugin.xml file. In this file you need to add the “car” extension to line 1743 as follows:


<structureCreator
extensions="jar"
class="org.eclipse.jdt.internal.ui.compare.JarStructureCreator"
id="org.eclipse.jdt.internal.ui.compare.JarStructureCreator">


Becomes

<structureCreator
extensions="jar,car"
class="org.eclipse.jdt.internal.ui.compare.JarStructureCreator"
id="org.eclipse.jdt.internal.ui.compare.JarStructureCreator">


You can now compare car files structurally.
