Can't get PMD 5.2.1 to check JSP files?
http://maven.apache.org/plugins/maven-pmd-plugin/pmd-mojo.html#language There is no way currently to have it check for "jsp" as the source type without modifying the plugin. You might want to try maven-exec with direct command line options of PMD as short-cut. http://mojo.codehaus.org/exec-maven-plugin/ http:://pmd.sourceforge.net/pmd-5.2.1/usage/running.html...
Why shouldn't all function arguments be declared final?
I can think of only 2 reasons not to make a parameter final: to save the use of a local variable if you need to overwrite the parameter's value in some edge cases (this is the reason you pointed out) to save 6 characters per parameter (not a good enough...

PMD plugin fails after upgrading Sonarqube to 4.5.4
There seem to be two problems showing up. First, PMD doesn't handle the NoClassDefFoundError similar to ClassNotFoundException - I've created an issue for PMD here. Second, Sonar doesn't seem to provide the complete project classpath to PMD. In order for PMD to be able to take advantage of typeresolution, PMD...
PMD multiple rulesets pass build but single ruleset fails build
I found the issue. There was an issue with Maven Plugin version 3.3 . Now I am using version 3.1 and the exact same code is working as expected.
Maven PMD plug-in not generating a report with 'mvn site' command or 'pmd:pmd'
The maven-pmd-plugin by default skips nowadays empty reports (property skipEmptyReport). You'll need to set this to false, to get in your site always a PMD/CPD report: <reporting> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-pmd-plugin</artifactId> <version>3.4</version> <configuration> <skipEmptyReport>false</skipEmptyReport> </configuration> </plugin> </plugins> </reporting> This applies for both PMD and...

You still have to configure each project individually though (for now,...
How to exclude a file for checking in PMD maven pom.xml file?

With pmd rulesets in maven, how do you select an individual rule?
This is not directly possible with maven. I'd recommend creating a custom ruleset file and reference this single ruleset in pom.xml instead. Custom Ruleset File: http://pmd.sourceforge.net/pmd-5.2.3/customizing/howtomakearuleset.html Example (filename custom-ruleset.xml): <?xml version="1.0"?> <ruleset name="Custom ruleset" xmlns="http://pmd.sourceforge.net/ruleset/2.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://pmd.sourceforge.net/ruleset/2.0.0...

PMD rules needs to be applied Junit files also?
This question is more a definition of what the software architect / technical lead wants. We have a common rule, what the quality of the tests have to be in the same quality as the code for production. But why? Since the test code is ensuring the quality of the...

See also the answer on the bug report #1339 and the changelog for 5.3.1: Language Java, ruleset design.xml: The rule “UseSingleton” has been renamed to “UseUtilityClass”. See also bugs #1059 and #1339. This is fixed with PMD 5.3.1 and later. For the time being, you'll need to manually fix the...

You can define a config file which includes the rulesets you wish to run. You can give this file as a parameter after the -R argument on the command line.

Using character instead of String for single-character values in StringBuffer append
java,string,optimization,string-concatenation,pmd
Appending a character as a char will always be faster than appending it as a String. But does the performance difference matter? If you just do it once, it doesn't. If it is inside a cycle repeating its body a million times, then yes, it might matter. If you already...
How to avoid premature initialization if the variable is only used inside of a scope
Use a single LoC for this: return someCondition() ?

Why PMD suggests to declare the JSONArray as final
PMD has detected that jsarray_com is never reassigned, so it's suggesting to add final to the declaration to make this fact explicit. When you see final, you immediately know that jsarray_com will always reference the same object. It makes the code slightly easier to follow, but you are free to...
Adding a ruleset to PMD?
This turned out be because I was using an old version of the Maven PMD plugin. The Maven plugin pulls in PMD by itself, which is convenient, but doesn't give you any control over what version it pulls in. The version I was using, 2.7.1, pulled in PMD version 4.3,...
