	abstract = {Software systems are evolving continuously in order to fulfill the ever-changing business needs. This endless modification, however, decreases the internal quality of the system over time. This phenomena is called software erosion, which results in higher development, testing, and operational costs. The SourceAudit tool presented in this paper helps managing the technical risks of software deterioration by allowing imme-diate, automatic, and objective assessment of software quality. By monitoring the high-level technical quality of systems it is possible to immediately perform the necessary steps needed to reduce the effects of software erosion, thus reaching higher maintainability and lower costs in the mid and long-term. The tool measures source code maintainability according to the ISO/IEC 25010 based probabilistic software maintainability model called ColumbusQM. It gives a holistic view on software quality and warns on source code maintainability decline.},

The plug-in extends the built-in Java code analysis engine of Sonar Qube with Front End ART{\textquoteright}s high-end Java code analysis engine. Most of Sonar Qubes original analysis results are replaced (including the detected source code duplications), while the range of available analyses is extended with a number of additional metrics and issue detectors. Additionally, the plug-in offers new GUI features on the Sonar Qube dashboard and drilldown views, making the Sonar Qube user experience more comfortable and the work with the tool more productive.},

	abstract = {Measuring source code maintainability has always been a challenge for software engineers. To address this problem, a number of metrics-based quality models have been proposed by researchers. Besides expressing source code maintainability in terms of numerical values, these models are also expected to provide explicable results, i.e. to give a detailed list of source code fragments that should be improved in order to reach higher overall quality. In this paper, we propose a general method for drilling down to the root causes of a quality rating. According to our approach, a relative maintainability index can be calculated for each source code element for which metrics are calculated (e.g. methods, classes). The index value expresses the source code element{\textquoteright}s contribution to the overall quality rating. We empirically validated the method on the jEdit open source tool, by comparing the results with the opinions of software engineering students. The case study shows that there is a high, 0.68 Spearman{\textquoteright}s correlation, which suggests that relative maintainability indices assigned by our method express the subjective feelings of humans fairly well.},
