Error Running PMD on Java 8

[Abhijith P]

Hi,

I am trying to use latest version of PMD 5.2.0 release on my Java project which used jdk 1.8. We are using Maven, hence I used maven-pmd-plugin:3.2 version to run pmd check.

PMD configuration is given below

                <plugin> 
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-pmd-plugin</artifactId>
                    <version>3.2</version>
                    <configuration>
                        <targetJdk>1.8</targetJdk>
                        <!-- Minimum Priority = 5 Maximum Priority = 0 -->
                        <failurePriority>2</failurePriority>
                        <verbose>true</verbose>
                        <rulesets>
                            <ruleset>custom.pmd.rulesets.xml</ruleset>
                        </rulesets>
                    </configuration>
                    <executions>
                        <execution>
                            <phase>verify</phase>
                            <goals>
                                <goal>check</goal>
                            </goals>
                        </execution>
                    </executions>
                    <dependencies>
                        <dependency>
                            <groupId>net.sourceforge.pmd</groupId>
                            <artifactId>pmd-core</artifactId>
                            <version>5.2.0</version>
                        </dependency>
                        <dependency>
                            <groupId>net.sourceforge.pmd</groupId>
                            <artifactId>pmd-java</artifactId>
                            <version>5.2.0</version>
                        </dependency>
                    </dependencies>
                </plugin>

I am getting below error during the build

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-pmd-plugin:3.2:pmd (pmd) on project copula-record: Execution pmd of goal org.apache.maven.plugins:maven-pmd-plugin:3.2:pmd failed: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-pmd-plugin:3.2:pmd: java.lang.NoSuchMethodError: net.sourceforge.pmd.lang.LanguageVersion.findByTerseName(Ljava/lang/String;)Lnet/sourceforge/pmd/lang/LanguageVersion;

Has anybody else encountered this and knows resolution? Thanks

Upgrading the maven-pmd-plugin to PMD 5.2.x is unfortunately not so easy - it needs additionally to the dependencies some code changes.
But it will happen hopefully soon.
