Plugin not load ruleset and verify all rules at eclipse startup

[Tenebrosful]

Hi,

I don't know why but sometimes the PMD don't want to read the ruleset file and try to verify all rules.

The only way that i found to fix that is switching git branch to a branch with different .pmd and .ruleset.xml then come back to branch and it correcly read it again.

My ruleset.xml

<ruleset xmlns="http://pmd.sourceforge.net/ruleset/2.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	name="pmd-eclipse"

Thanks for the report. Would you mind to share your workspace log file (eclipse error log) the next time this happens?. The plugin has also a logging setting, you could also configure this in the preferences and share the log file of the plugin only.

[Tenebrosful]

Hummm, according to logs it looks like the problem is from the .ruleset.xml

After some tests, removing exclude-pattern remove 1 error, (what is strange because there are in the official documentation, i will looks for the others

[Tenebrosful]

Ok found it.

<rule ref="category/java/codestyle.xml/FieldNamingConventions">
  <properties>
	  <property name="finalPattern" value="[A-Z][A-Z0-9_]*" />
  </properties>
</rule>

was the probleme because property finalPattern is misspelled and so thats make all the file crashing. But i still have no idea about the <exclude-pattern>, if you can help me about that

[chovyy]

I have a similar error. Would be nice to receive a proper error message or warning in such cases.

[adangel]

was the probleme because property finalPattern is misspelled and so thats make all the file crashing

Yes, the property name is "finalFieldPattern" (https://docs.pmd-code.org/latest/pmd_rules_java_codestyle.html#fieldnamingconventions)

The exclude pattern in the ruleset xml file is supposed to be a valid java regular expression. I don't think, we are explicit about the syntax of these patterns in the doc (https://docs.pmd-code.org/latest/pmd_userdocs_making_rulesets.html#filtering-the-processed-files). I know, that the eclipse plugin internally used to use ant-like pattern - so converting between the two might also contain some bugs.

Looking at your pattern, I think, the following produces a syntax error:

<exclude-pattern>*.min.js</exclude-pattern>

It should be

<exclude-pattern>.*\.min\.js</exclude-pattern>

warning: I'm not sure about the escapes for ".". Remember, that a dot "." matches any character and not only a dot.

Your include pattern also don't look correct, so you probably don't pick up all files you want:

<include-pattern>./WEB-INF/src/*</include-pattern>

instead use

<include-pattern>/WEB-INF/src/.*</include-pattern>

[Tenebrosful]

About the exclude pattern, there are detected like not allowed
