I had an issue where I needed to replace all backslashes in a Maven property with forward slashes. The build helper plugin did the trick.
org.codehaus.mojo build-helper-maven-plugin ${maven.build-helper.version} regex-property regex-property some.property.replaced ${some.property} \ / false
To validate that this all worked, the antrun plugin can echo out the new property:
org.apache.maven.plugins maven-antrun-plugin ${maven.antrun.version} echo-property run some.property.replaced=${some.property.replaced}
