Re: [gradle-user] copy task and force overwrite?

Hi.

First off, thanks for a GREAT build tool.

In my multiproject build I have something like this:

subprojects {
   <snip stuff>
   task filterResources(dependsOn: updateBuildProperties)<<  {
     buildProps = new Properties()
     file("../build.properties").withInputStream {
       buildProps.load(it)
     }
   }
   processResources.dependsOn filterResources
   processTestResources.dependsOn filterResources
}

(Yes, I do know that build.properties is loaded for each subproject -
working on it :-) )
and then each project extends the filterResources task like so:

project(":some-jpa") {
   <snip stuff>
   filterResources.doLast {
     file("resources/META-INF/persistence.xml").delete()
     file("conf/hibernate.properties").delete()
     file("conf/hibernate.reveng.xml").delete()
     assert file('templates/persistence.xml').exists()
     assert file('templates/hibernate.properties').exists()
     assert file('templates/hibernate.reveng.xml').exists()
     copy {
       into 'resources/META-INF'

Should this be into 'src/main/resources/META-INF' ?

       from('templates')
       include 'persistence.xml'
       filter(ReplaceTokens, tokens: buildProps)
     }
     copy {
       into 'conf'
       from('templates') {
         include 'hibernate.reveng.xml'
         include 'hibernate.properties'
       }
       filter(ReplaceTokens, tokens: buildProps)
     }
   }
}

With this approach, I hoped that the processResources task from the
java plugin would pick up on changes to the resource files. But that
is not the case. If I change a property, and build with gradle, then
the filtered file contains the changes, but the procssesResources is
claimed to be up-to-date:

<snip from gradle build>
:updateBuildProperties
:some-jpa:filterResources
:some-jpa:processResources UP-TO-DATE

Is there someway to force processResources overwrite existing files? I
was thinking along the lines of a "force" attribute?

I track the git repository for, and I currently run gradle version
0.9-20100611103621+0200
