10 years ago PMD uses regular expressions to define the include and exclude pattern and (unfortunately) silently ignores an invalid pattern. In your case both the exclude and the includes pattern are invalid and that is why PMD analyses the SQL files in the first place. You might want to change your patterns to the following:
<exclude-pattern>.*</exclude-pattern>
<include-pattern>.*\.java$</include-pattern>I tried to reproduce the problem with my own SQL files but was unable to do so. My currently best guess for the reason why mvn pmd:pmd runs without issue and eclipse-pmd hangs is that mvn pmd:pmd does not actually analyse the SQL files. Please make sure that
- your maven configuration uses PMD 5.1.1. The maven-pmd-plugin currently uses PMD 5.0.5 and SQL support was only introduced with PMD 5.1.
- your maven configuration includes all files. The maven-pmd-plugin default include pattern is */.java which excludes your SQL files.
- you don't use any include/exclude patterns in your PMD rule set file.
Your maven configuration should look like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<version>3.1</version>
<configuration>
<targetJdk>1.7</targetJdk>
<rulesets>
<ruleset>${basedir}/pmd.xml</ruleset>
</rulesets>
<verbose>true</verbose>
<includes>
<include>**/*</include>
</includes>
</configuration>
<dependencies>
<dependency>
<groupId>net.sourceforge.pmd</groupId>
<artifactId>pmd</artifactId>
<version>5.1.1</version>
</dependency>
</dependencies>
</plugin>Please let me know if the above maven configuration also hangs when analysing your SQL files. This would help me find out if this is a problem with eclipse-pmd or PMD itself.

I'm trying to enable the PMD nature on a Maven module project that contains 540 .sql files and 290 .java files. When I do this Building workspace hangs at 43% on "Setting classpath containers: Invoking 'PMD Builder' on '/db'." The Eclipse process has the CPU pegged at 700+% (4 cores, hyperthreaded, so 800% is the max). After running for over an hour the build eventually fails having run out of "Java heap space" (-Xmx1536m -XX:MaxPermSize=512m). After the failure I can remove the PMD nature from the project in question and restart Eclipse.
I took occasional stack dumps while it was running, and a single ever-present stack for PLSQLParser stood out:
Assuming I've specified the patterns correctly my rule set excludes all but .java files, and I don't reference any of the "rulesets/plsql/*" rule sets:
When I run
mvn pmd:pmdon this project it completes without issue in a few seconds.
