Edward Ciramella commented on MCHECKSTYLE-59:
---------------------------------------------
I'm running maven 2.2.1, Checkstyle plugin 2.5 and I'm running into this exact
same problem:
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error during page generation
Embedded error: Error rendering Maven report: Failed during checkstyle
configuration
Unable to instantiate GenericIllegalRegexpCheck
Our Module is configured as follows:
<module name="GenericIllegalRegexp">
<property name="format" value="System\.out\.print"/>
<property name="message" value="System.out.print not allowed"/>
</module>
This is just like the example checkstyle gives in their documentation.
Full output here:

[INFO] ------------------------------------------------------------------------
> Checkstyle Report fails if propertyExpansion contains backslash characters
> --------------------------------------------------------------------------
>
> Key: MCHECKSTYLE-59
> URL: http://jira.codehaus.org/browse/MCHECKSTYLE-59
> Project: Maven 2.x Checkstyle Plugin
> Issue Type: Bug
> Affects Versions: 2.1
> Environment: Windows XP, JDK 1.4, Maven 2.0.4
> Reporter: Carsten Karkola
> Assignee: Dennis Lundberg
> Fix For: 2.2
>
> Attachments: MCHECKSTYLE-59-PATCH.patch, MCHECKSTYLE-59-PATCH2.patch
>
>
> The chechkstyle plugin fails on windows plattforms, if the propertyExpansion
> element contains file names like
>
> mms.suppressions.file=${basedir}/../../project/resources/checkstyle/suppressions.xml
> The backslashes in ${basedir} (like D:\foo\bar) are missing (D:foobar) and
> checkstyle fails. It seems to be an issue with StringInputStream.
> I've replaced the following old code in CheckstyleReport.java
> {code}
> if ( StringUtils.isNotEmpty( propertyExpansion ) )
> {
> p.load( new StringInputStream( propertyExpansion ) );
> }
> {code}
> with the new Code
> {code}
> if ( StringUtils.isNotEmpty( propertyExpansion ) ) {
> BufferedReader reader = new BufferedReader(new
> StringReader(propertyExpansion));
> String line = reader.readLine();
> while (line != null) {
> int delimPosition = line.indexOf('=');
> if (delimPosition > -1) {
> String name = line.substring(0, delimPosition).trim();
> delimPosition++;
> if (delimPosition < line.length()) {
> String value = line.substring(delimPosition).trim();
> if (value.length() > 0) {
> p.put(name, value);
> getLog().info("Property: " + name + " = " +
> p.getProperty(name));
> }
> }
> }
> line = reader.readLine();
> }
> reader.close();
> }
> {code}
> and it works.
