I wanted to be able to do this in file names, so I came up with a hack for a camel case artifactId
property:
<requiredProperty key="artifactIdCamelCase">
<defaultValue>${artifactId.replaceAll("^a|-a", "A").replaceAll("^b|-b", "B").replaceAll("^c|-c", "C").replaceAll("^d|-d", "D").replaceAll("^e|-e", "E").replaceAll("^f|-f", "F").replaceAll("^g|-g", "G").replaceAll("^h|-h", "H").replaceAll("^i|-i", "I").replaceAll("^j|-j", "J").replaceAll("^k|-k", "K").replaceAll("^l|-l", "L").replaceAll("^m|-m", "M").replaceAll("^n|-n", "N").replaceAll("^o|-o", "O").replaceAll("^p|-p", "P").replaceAll("^q|-q", "Q").replaceAll("^r|-r", "R").replaceAll("^s|-s", "S").replaceAll("^t|-t", "T").replaceAll("^u|-u", "U").replaceAll("^v|-v", "V").replaceAll("^w|-w", "W").replaceAll("^x|-x", "X").replaceAll("^y|-y", "Y").replaceAll("^z|-z", "Z")}</defaultValue>
</requiredProperty>
That will convert any artifactId
that follows the naming convention of hyphenated, lower case a-z
to camel case. From some limited testing, the format is fragile so small edits such as line breaks and regex additions may stop Velocity from replacing the property.
Should work on Maven versions after 2.1 (when this bug was fixed). My version:
> mvn -v
Apache Maven 3.2.5 (12a6b3acb947671f09b81f49094c53f426d8cea1; 2014-12-14T11:29:23-06:00)
Also here is a sometimes-useful, unhyphenated version of artifactId
:
<requiredProperty key="artifactIdUnhyphenated">
<defaultValue>${artifactId.replace("-","")}</defaultValue>
</requiredProperty>
