Eclipse PMD Cannot find basic.xml

Question

When I try to start pmd for a project in Eclipse / Juno, I get this error.

An internal error occurred during: "ReviewCode". Couldn't find the class Can't find resource rulesets/basic.xml. Make sure the resource is a valid file or URL or is on the CLASSPATH. Here the current classpath: C:\eclipsejuno\eclipse\\plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar 

Does anyone know how I can solve this problem?

Answer 1

I also saw this problem with the command line version. In the latest version, the path to the rulesets/java/basic.xml

They seem to have changed the default paths between versions. You either need to manually update your paths in the PMD configuration, or upgrade to the latest version.

Answer 2

If there is a ".pmd" file in your project and a referent with ruleset.xml, you can solve your problem by choosing between the above solutions.

• delete the .pmd file
• open your ruleset.xml file and your configuration according to this sample

 <rule ref="rulesets/basic.xml" /> 

TO

 <rule ref="rulesets/java/basic.xml" /> 

Answer 3

The rule change rule / java / tip helped me, but I also had to change one rule:

 <rule ref="rulesets/java/controversial.xml/UnusedModifier"> <priority>5</priority> </rule> 

to

 <rule ref="rulesets/java/unusedcode.xml/UnusedModifier"> <priority>5</priority> </rule> 

Here is my sonar PMD configuration file that works for me with PMD 4.0.2 plugin .:

Answer 4

I was getting this error when trying to update a Maven project in Eclipse. The problem for me was that I used two different PMDs, one of which was installed as an Eclipse plugin, and the other was loaded by Maven from the pom.xml file of the parent project. So I needed to do this to remove the Eclipse PMD plugin and after that no longer got the error.

Answer 5

In my case, I have my own pmdRuleSet.xml file and it looks like this:

 <rule ref="pmd-rulesets/java/codesize.xml/ExcessiveMethodLength"> <properties> <property name="minimum" value="10"/> </properties> 

And it throws an error if I change "pmd-rulesets" to "ruleset" and the path in pmdRuleSet.xml, obviously then everything is ok.

Answer 6

if you have to deal with complex project settings, you can use this line to convert each .pmd file

 find . -name .pmd -exec sed -i.bak 's/rulesets\/basic.xml/rulesets\/java\/basic.xml/g' {} \;
