A semi automatic tool for finding Java key classes in open source systems
Steps to find key classes:
Setup Tools
1 - Execution trace: trace extractor is a tool based on AspectJ. Unzip TraceExtractor and configure trace extractor on Eclipse IDE. Convert your Java project in an AspectJ project and in sequence on the option Aspect Build -> Inpath add the trace extractor tool.
2- Trace compressor: Unzip TraceCompressor and in sequence configure on Eclipse IDE
3- Keecle: to find key classes, follow the steps:
3.1- Create Subtrees, from execution trace
3.2- Remove identical subtrees
3.3- Train & Test: creat files .arff wiht test and training data
3.4- Downloading and setup Weka software (https://www.cs.waikato.ac.nz/ml/weka/) to classify the trace subtrees
3.5- Key classes: from result of the classification of subtrees on Weka and in sequence are extracted the key classes.
