First, basic knowledge PMD is a tool for parsing Java code errors. Unlike other analysis tools, PMD learns code errors through static analysis. That is, you report an error without running the Java program. PMD comes with a number of rules that can be used directly, using these rules to identify many problems with Java source programs, such as unused variables, e

about PMD PMD is scanning Java source code and looking for potential problems: a null-and-void capture block (catch blocks) never used parameter NULL if declaration duplicate import declaration never used private method isolation Class short or long type variable and method name PMD has plug-ins with the following software: JEdit, JBuilder, Netbeans/sun one Studi

Here are a few examples of potential bugs: Synchronization on Boolean cocould lead to deadlock May expose internal representation by returning reference to mutable object Method uses the same code for two branches Bugs are like human relations, it is not always easy to understand the problem as there are too parameters to take into account. can be a good idea to som

Objective:PMD is a static code analysis tool that can automatically detect various potential defects as well as unsafe or non-optimized code.PMD is more focused on pre-detection flaws, and it provides a highly configurable rich set of rules that users can easily configure to treat specific projects using those rules.Installation and use:1.

PMD is a source code parser. It finds common programming flaws, such as unused variables, empty catch blocks, unnecessary object creation, and so on. It supports Java, JavaScript, Salesforce.com Apex, Plsql, Apache Velocity, XML, XSL, and more.In addition, it includes CPD (copy-paste-detector, copy-paste detector). CPD in Java, C, C + +, C #, Groovy, PHP, Ruby, Fortran, JavaScript, Plsql, Apache Velocity, Scala, Objective C, Matlab, Python, Go, Duplic

Label:FindBugs, Checkstyle, PMD installation and use of the eclipse plugin First, what is FindBugs, Checkstyle, PMD Findbugs, Checkstyle, and PMD can be plugged into eclipse as plug-ins, but there are also separate tools to implement their functions, such as the Findbugs tool that can be used without having to plug into eclipse. The functions of the three are sho

ArticleDirectory E: \ SRC \ confirmratelimitactivity I didn't know about PMD before. I recently heard about PC lint before I started to get in touch with it. If such a good tool is used, it can help me a lot better.CodeHabits and norms are of great help ~ Let's see how he works. Many companies use PC lint as a static code review tool for C/C ++. It is said that Microsoft regards PC lint review with no errors or warnings as the firs

To improve the quality of your code, in addition to improving logical control and understanding of business processes, there is room for improvement in the code itself, such as some potential problems that can be avoided early. Similar to the content of the coding code, if all rely on the coder to do their own checks, it will undoubtedly require a lot of work, if you can use the static inspection tools to check the code, then greatly improve the efficiency of coding. This article is the first of

Before formally entering the test, it is helpful to do some static code analysis and code review to improve the quality and the system, the above is the data proofPMD It is a Java source code parser based on a static rule set that identifies potential problems such as:– Possible bug--empty try/catch/finally/switch blocks.– Useless codes (Dead code): Useless local variables, method arguments, and private methods.– An empty If/while statement.– Overly complex expressions-unnecessary if statements,

1. Use of MVN Checkstyle plugin You can get Checkstyle reports on target/site/checkstyle.html and target/without any setup, directly running MVN checkstyle:checkstyle Checkstyle-result.xml. The check rule for the Checkstyle used is Sun_checks.xml-sun Microsystems Definition (default). If you want to use custom rules, the version above maven3.0 needs to be added under the Pom.xml And it should be The above is for a single module project. For pro

PMD 5.7.0 was released. PMD is a Java program code checker that is released using the BSD protocol. The tool can check whether the Java code contains unused variables, contains empty fetch blocks, contains unnecessary objects, and so on. The software is powerful and highly efficient, and is a good helper for Java programmer Debug. Notable changes are: the "fielddeclarationsshouldbeatstartofclass" rule in th
