copied!<h3>Summary</h3> <p>There is also CloneDetective, Simian and Simscan. <a href="http://wwwbroy.in.tum.de/~juergens/publications/ICSE2009_FRD_0232_Juergens.pdf" rel="noreferrer">This paper from the International Conference on Software Engineering 2009</a> compares them, and PMD's CPD. </p> <h3>In detail</h3> <p>One tool that can handle several languages is <strong><a href="http://www.clonedetective.org/" rel="noreferrer">CloneDetective</a></strong> (based on ConQuat, Continuous Quality Assessment Toolkit): ABAP, ADA, Java, C#, C/C++, Visual Basic, Cobol, PL1.</p> <p>Another tool is <strong><a href="http://www.harukizaemon.com/simian/" rel="noreferrer">Simian, the Similarity Analyser</a></strong>, which identifies duplication in Java, C#, C, C++, COBOL, Ruby, JSP, ASP, HTML, XML, Visual Basic, Groovy source code and even plain text files. It runs on JVM and .NET. </p> <p>Actually, if you look at .NET, there are a lot of copy paste detection tools...</p> <p><strong><a href="http://blue-edge.bg/download.html" rel="noreferrer">SimScan, the SimilarityScanner</a></strong> is an Eclipse/IDEA/JBUILDER plugin that finds duplicated or similar fragments of code in large Java source code bases. I don't know it, and have no idea what "similar fragments" means. It sounds like it might also just look isolatedly in single projects, but the IntelliJ-Screenshots look nifty.</p> <p><a href="http://wwwbroy.in.tum.de/~juergens/publications/ICSE2009_FRD_0232_Juergens.pdf" rel="noreferrer">This paper from the International Conference on Software Engineering 2009</a> compares CloneDetective, PMD's CPD, Simian and Simscan.</p> <p>Just as PMD's copy & paste finder is actually called <strong>CPD</strong> for "copy paste detector", using that term as the terminus technicus for googling helps. Another term often used is "clone detection". </p>
