Converting .properties to UTF8
Upon the packaging of my war, I want to convert all .properties files to
utf8. Can I do this with straight maven or will I need to run an ant task OR
write my own plugin?
Thank you for your time,
Daniel.

Currently my native2ascii goal is configured:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>native2ascii-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>native2ascii</goal>
</goals>
<!-- specific configurations -->
<configuration>
<encoding>UTF8</encoding>
<src>${basedir}/resources</src>
<dest>target/classes</dest>
<includes>**/*.properties</includes>
</configuration>
</execution>
</executions>
</plugin>
Does this mean I need to break away from UTF8 and set the encoding value to
something else? Am I just missing the point?

With JDK 6 this has changed, you may also use different encodings. However,
keeping .property files in ISO-8859-1 is good practice and I am not
astonished, that some tools take this for granted.

If your .properties files should be read by the java.util.Properties class
please keep in mind that they HAVE to be encoded in "ISO 8859-1" a.k.a.
"latin1".
see http://java.sun.com/j2se/1.5.0/docs/api/java/util/Properties.html
"The load and store methods load and store properties in a simple line-
oriented format specified below. This format uses the ISO 8859-1 character
encoding. Characters that cannot be directly represented in this encoding can
be written using Unicode escapes ; only a single 'u' character is allowed in
an escape sequence. The native2ascii tool can be used to convert property files
to and from other character encodings."

If there is no maven plugin just use antrun
(http://maven.apache.org/plugins/maven-antrun-plugin/)
Just bind to the phase you want your ant task to run when specifying
the ant task in your pom.

We want to go from native to UTF-8. We can't develop in UTF-8 directly due
to various bugs we've run into with Eclipse (everyone uses it but me) and
some of our other tools. Before we were using some ant task. I'd like to
keep with pure maven, though.

what is your original encoding? why not use UTF-8 directly when editing
files?
We usually want exactly the opposite, i.e. write our .property files
using UTF-8 and in our native language, then use native2ascii executable
from the JDK (think there is a maven plugin for that and an ant task is
certainly available) to convert the files in ascii to ensure proper
interpretation of prop values.
