Motivation
• A software system has many dependencies
– Programming language level
• Finding relevant dependencies
• Displaying dependencies in an understandable
form
• Usable
• Simple

Overview
• Class Dependency Analyzer (CDA)
– Find dependencies
– Visualize them
– Relatively Usable and Simple
• Granularity
– Package, class, jar, directory structure
Compiling OODT
•
•
•
•
You will need Apache Maven
Please refer to the Maven website about how to install Maven
Maven will need to download dependencies
Compiling all of OODT takes long
– If you want try compiling all of OODT, going to the top directory
containing all the source directories and a pom.xml file and type
• mvn install
• You can change to each source directory in the OODT tar.gz file that
has a pom.xml and use the following command to compile
– mvn install
• Compiling with Maven
– Go to the core directory of OODT and type “mvn install” without the
quotes
Installation of CDA
• Unzip the archive pf-cda-x.x.zip to any directory you
want.
• Then ensure that environment variable JAVA_HOME is
set to a Java Runtime Environment 1.5.0 or higher.
• Open a command shell in the directory to which you
unzipped the archive.
• Run the script sssgen.bat or sssgen.sh to generate a
start shell script that invokes the tool with absolute
classpath entries in order to allow to start it from
anywhere in the file system.
• Eventually a run.bat (or run.sh on Linux) must be
available in the directory
