Patterns containing any of '^', '$', '<', '>' do not match

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Specify regex pattern containing any of '^', '$', '<', '>'

What is the expected output? What do you see instead?

Pattern "^.*$" should match every input line but matches no line.
Pattern "<build>" should match input "<build>" but matches nothing.

What version of the product are you using?

1.5.3

Please provide any additional information below.

There is no match regardless of whether the pattern is wrapped in a CDATA block 
or the '>' and '<' are written in escaped form.

OS: OSX
Java: 7 update 67
Maven: 3.2.1

Can you post all the configuration?

Also, make sure to use: <regex>true</regex> when using a token containing regex 
for matching.

I have downgraded to 1.5.2 and relative paths do work in that version.

The configuration I use is as follows. For testing I added the pattern "^.*$" 
with an empty string as replacement value, which I think should yield a file 
with empty lines. But it does not. The other patterns match, yielding some 
empty lines in the output file.

<plugin>
    <groupId>com.google.code.maven-replacer-plugin</groupId>

                <!-- For whatever reason, the plugin refuses to match '<', '>', '^', and '$'. CDATA section or not. -->

I have exactly the same problem.

I want to remove all spaces at each line before a tag with the following 
configuration:

            <plugin>
                <groupId>com.google.code.maven-replacer-plugin</groupId>
                <artifactId>replacer</artifactId>
                <version>1.5.3</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>replace</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <basedir>${project.build.directory}</basedir>
                    <filesToInclude>${project.build.finalName}/WEB-INF/views/**/*.jsp</filesToInclude>
                    <token>>\s*<</token>
                    <value>><</value>
                    <regex>true</regex>
                    <regexFlags>
                        <regexFlag>MULTILINE</regexFlag>
                    </regexFlags>
                </configuration>
            </plugin>

Doesn't work...so it's exactly the same...
