问题 I am upgrading my existing SonarQube 3.7.4 installation to the new LTS release 4.5.4 . I'd like to reuse my ruleset and I am using the sonarqube ant task (as before) to analyze my projects. After upgrading the sonar installation and the ant task to 2.2 without changing anything else I'm getting a NoClassDefFoundError while executing the ant task: build.xml:1659: org.sonar.runner.impl.RunnerException: Unable to execute Sonar at org.sonar.runner.impl.BatchLauncher$1.delegateExecution

问题 I'm attempting to exclude a certain rule from pmd using the maven-pmd-plugin (in a multi-module maven project). Approach: Using the excludeFromFailureFile http://maven.apache.org/plugins/maven-pmd-plugin/examples/violation-exclusions.html Ideally, I want to exclude this rule for the entire product (based on a parent package), however,to being with I tested for a particular class - even that is not working. Environment Java 7, Maven 3.0.3 <plugin> <groupId>org.apache.maven.plugins</groupId>

@SuppressWarnings more than one rule not working

问题 PMD and SonarQube a nice tools but I have problems trying to suppress PMD warnings. We use Lombok a lot in our project, so many of the model classes have a: @SuppressWarnings("PMD.UnusedPrivateField") as an class-level annotations. This works fine. The problem is, that if I wan't to ignore one more rule, I would expect the following syntax: @SuppressWarnings(value = { "PMD.UnusedPrivateField", "PMD.SingularField" }) This looks like the correct syntax, also reading the implementation of the

问题 In our project for chained if/else/if we would like to have following formatting: if (flag1) { // Do something 1 } else if (flag2) { // Do something 2 } else if (flag3) { // Do something 3 } And forbid following one: if (flag1) { // Do something 1 } else { if (flag2) { // Do something 2 } else { if (flag3) { // Do something 3 } } } Is there some predefined rule in either of listed above static code analysis tools to force this code style? If no - I know there is an ability to write custom

Add an empty string vs toString - why is it bad?

阅读更多关于 Add an empty string vs toString - why is it bad?

问题 According to the tool PMD, the following is a bad practice: String s = "" + 123; // bad String t = Integer.toString(456); // ok This is an inefficient way to convert any type to a `String`. Why is it a bad thing to do? 回答1: String s = "" + 123; // bad String t = Integer.toString(456); Will be compiled to: String s = "123"; String t = Integer.toString(456); so: "" +123 is obvious slightly better! Checked with JAD public static void main(String args[]) { // 0 0:ldc1 #16 <String "123"> // 1 2

Which is the highest priority in PMD?

阅读更多关于 Which is the highest priority in PMD?

问题 Maybe it's just me, but I can't find information which is the highest priority in PMD: 1 or 5 ? Because of http://pmd.sourceforge.net/running.html and the mention of the command line parameter -minimumpriority I think 5 is the highest and 1 is the lowest value. Am I right? 回答1: Actually 1 is highest priority and 5 is lowest priority. You can check the exported rule set, where <rule ref="rulesets/imports.xml/ImportFromSamePackage"/>  <rule ref="rulesets/imports.xml

How to Add custom JAR to the “eclipse-pmd” plugin?

阅读更多关于 How to Add custom JAR to the “eclipse-pmd” plugin?

问题 Installed the Eclipse PMD plugin (written by Philip Graf ) from here. I tried to associate a custom PMD rule classes JAR but couldn't find a provision for it. This JAR contains custom rule classes (that extends AbstractJavaRule indirectly). So is there any way to configure eclipse-pmd plugin to accept this custom JAR? My custompmd.jar has this structure: custompmd.jar └─com/pmd/custom └─AvoidHardcodingRule.class └─AvoidCatchWithoutLogErrorRule.class └─etc... Simply putting it in plugins
