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,
When people talk about the code rule engine. Everyone likes to stand on their own and say that they prefer tools, rather than other tools.
For instance, a PMD supporter cocould say:
"Checkstyle is a stupid tool consuming time to search for tab characters when PMD is a smart one that can do the job alone as a good soldier, findbugs is very good for resource consumption and Macer is... Uh, what is Macer? "

Java advanced (iii) ------ java programming specifications-Comparison of FindBugs, PMD, and CheckStyle code quality detection tools
In the previous article, we have learned how to automatically set the code format in myeclipse.
During the development process, we will find that we do not have much time to perform code check and review. However, we can use tools to automatically check the code to improve work efficiency. FindBugs,
Today again want to start Java Code Static Detection Tool utilization problem, mainly try to use PMD again, found a lot of code coding problems and good code recommendations, and learned a lot of their own prior to the Java convenient basic knowledge, feel very good, the relevant understanding of the good rules of the recollection summary, In the future coding process to be ready to use the Code static Check tool, with good code static check tool habi

PMD is an excellent tool for code checking of Java programs. It can check whether the Java code contains unused variables, whether they contain empty fetch blocks, whether they contain unnecessary objects, and so on.But in the course of use, you will find that there are a lot of error and warning in the PMD plugin, although PMD encourages programmers to improve t

In fact, a dependent detection, but now the project is using the SSH architecture, the existing dependency checking tool, the support for spring is not very good, and then give up.
For the choice of tools, tight is familiar with the choice of Checkstyle, FindBugs and PMD CPD tools.

It has been May, and it took more than ten days to study the results. Write a log to commemorate it.It is a three-dimensional model format and is mainly used in mikumikudance and pmdeditor. There are fewer descriptions about the format, so my research mainly involves the MMD library of itsuhane.The PMD format file is also a simple binary file, because the file form
The PMD plugin installation address is: Http://pmd.sourceforge.net/eclipse
After the PMD plug-in is installed, it consists of 2 parts: CPD and PMD.
CPD is used to check for repetitive code (for example, by copying and pasting the resulting code)
