Body
I get the following error when executing the command <code>mvn checkstyle:checkstyle</code>: <pre><code>An error has occurred in Checkstyle report generation. ... Caused by: com.puppycrawl.tools.checkstyle.api.CheckstyleException: cannot initialize module TreeWalker - Unable to instantiate GenericIllegalRegexp at com.puppycrawl.tools.checkstyle.Checker.setupChild(Checker.java:178) at com.puppycrawl.tools.checkstyle.api.AutomaticBean.configure(AutomaticBean.java:184) at org.apache.maven.plugin.checkstyle.DefaultCheckstyleExecutor.executeCheckstyle(DefaultCheckstyleExecutor.java:170) at org.apache.maven.plugin.checkstyle.AbstractCheckstyleReport.executeReport(AbstractCheckstyleReport.java:259) ... 24 more Caused by: com.puppycrawl.tools.checkstyle.api.CheckstyleException: Unable to instantiate GenericIllegalRegexp at com.puppycrawl.tools.checkstyle.PackageObjectFactory.createModule(PackageObjectFactory.java:155) at com.puppycrawl.tools.checkstyle.TreeWalker.setupChild(TreeWalker.java:161) at com.puppycrawl.tools.checkstyle.api.AutomaticBean.configure(AutomaticBean.java:184) at com.puppycrawl.tools.checkstyle.Checker.setupChild(Checker.java:157) ... 27 more Caused by: com.puppycrawl.tools.checkstyle.api.CheckstyleException: Unable to instantiate GenericIllegalRegexpCheck at com.puppycrawl.tools.checkstyle.PackageObjectFactory.doMakeObject(PackageObjectFactory.java:98) at com.puppycrawl.tools.checkstyle.PackageObjectFactory.createModule(PackageObjectFactory.java:152) ... 30 more </code></pre> I guess the error has to do with the rules created with an older version of checkstyle. The checkstyle plugin configuration inside the pom.xml is: <pre><code>... <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-checkstyle-plugin</artifactId> <version>2.9.1</version> <configuration> <configLocation>checkstyle.xml</configLocation> <headerLocation>LICENSE.txt</headerLocation> </configuration> </plugin> ... </code></pre> Is there a way or tool to migrate the rules to make them checkstyle 5.5 compatible? (Other than overviewing rule per rule based on the checkstyle documentaion)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
