EspaceString doesn't work

I also try with #%comment to espace:§@toto@ and I have the same problem.

IMHO this must be WON'T FIX
see http://maven.apache.org/plugins/maven-resources-plugin/examples/escape-filtering.html
escapeString is here to prevent escaping.
So in your line : #%comment to espace:§@toto
I don't see any filtering because the end token is missing.
Désolé

I agree with Olivier. This is working as it should. No change is needed.

By the way, your sample project has an invalid character as the escapeString. It just shows up as a question mark icon in my Java based IDE. That could explain why you are having problems.

As I said, I also try with #%comment to espace:§@toto@ and I have the same problem.
I don't think it is working as it should.
Isn't it the same to RESOURCES-110

Also, how to deal with this case?

question=@message@
mailbox =contact@toto.com

where I want to escape the @ of contact@toto.com

Dennis, In fact I wasn't in UTF-8 encoding but it does not change anything.

With the last 2.5-SNAPSHOT it's now working. I do not have to define an escapeString in my property file

#%comment:@toto
question=@message@
mailbox =contact@toto.com
other.question=@validation@

#%comment: @toto
question=A nice message...
mailbox =contact@toto.com
other.question=A validation message ?

But, strangely, I have to configure the maven resource plugin with escapeString otherwise it does not work.

Also, #%comment to espace:§@toto does not work but it don't need it now.

Your example

question=@message@
mailbox =contact@toto.com

works out of the box in 2.5-SNAPSHOT. You don't have to add any escapeString for it to work.

The escapeString parameter has no default value, which is why you have to configure it.

The escapeString parameter seems to have default value

Expression preceded with the String won't be interpolated \${foo} 
will be replaced with ${foo}.
Default value is: ${maven.resources.escapeString}.

Also I don't understand why I have to configure the plugin if I don't need any escapeString. If I remove this configuration, it does not work...

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-resources-plugin</artifactId>
   <version>2.5-SNAPSHOT</version>
   <configuration>
     <escapeString>§</escapeString>
   </configuration>  
 </plugin>

The escapeString does not have a default value. The text you are referring to is the "expression" for the parameter. This is a way to configure a value for through the command line. It would look like this:

mvn process-resources -Dmaven.resources.escapeString=§

By the way, where did you find that text? We should try to improve the documentation.

If you do not configure the escapeString no escaping should be done. So your example should work. Can you assemble a zip-file with the files you are using so that we can verify this?

documentation fixed in rev 1059420

@Dennis: The text was taken from the documentation (http://maven.apache.org/plugins/maven-resources-plugin/resources-mojo.html). Thanks @Olivier for the fixed.

You can try with the attached example maven-resources-plugin-EscapeString.zip
If I remove the resource plugin configuration, I have this result (even with the last 2.5-SNAPSHOT version)

#%comment: @toto
question=@message@
mailbox =contact@toto.com

#%comment
other.question=A validation message ?

Rémy,

Here's a sample project that looks like the one you are describing. This is working nicely for me. Can you please try it and see if it works for you?

Dennis,

It works well for both your sample project and mine too (today).
I don't know why yesterday mine didn't worked.

Anyway, I'm glad that it's working as expected.
Thanks.

Thanks for helping us verify that it is fixed.
