Replace a resource file in a WAR file in Gradle 3.5

I scanned the whole internet and found lots of answers, but neither worked for me properly.

I have the 2 files under

src/main/resources/
                  cluster.xml
                  a/
                    cluster.xml

In my war file I want to have the later.

So I tried:

war {
  from( 'src/main/resources' ){
    exclude 'cluster.xml'
    include 'a/cluster.xml'
    into 'WEB-INF/classes'
  }
}

and it put 2 copies of a/cluster.xml into WEB-INF/classes/a and a single cluster.xml into WEB-INF/classes.

I tried also using webInf{} with no success either.

UPDATE:

To make it a bit clear. I have a Grails 3.x / Springboot app. It has the default gradle task bootRun which runs the app in development mode w/o building the war-file. In this case the file resources/cluster.xml is picked from the classpath and the app works like charm.

For the war task I want to replace this single file, without breaking the bootRun task and keeping the whole config as simple as possible.

To only modify the WAR, you'll need to access the rootSpec and perform some logic against the cluster.xml files.

war {
    rootSpec.includeEmptyDirs = false
    rootSpec.filesMatching('**/cluster.xml') { details ->
       if (details.sourcePath == "cluster.xml") {
           details.exclude()
       }
       if (details.sourcePath == "a/cluster.xml") {
           details.path = "WEB-INF/classes/cluster.xml"
       }
    }
}

Rather than relying on exclude which can be confusing, have you considered combining multiple FileTrees together? I much prefer adding two roots together rather than hacking excludes and moves within a single root

eg

- src/main/resources - Common stuff goes here
- src/a/resources/cluster.xml - Version A of cluster.xml
- src/b/resources/cluster.xml - Version B of cluster.xml

Once you've separated into different directories, you can add together the FileTrees that you need in a given situation. IMHO this is much better than using an exclude

Try this :

sourceSets.main.resources.exclude '**/cluster.xml'

war {
  from( 'src/main/resources' ){
    exclude 'cluster.xml'
    include 'a/cluster.xml'
    into 'WEB-INF/classes'
  }
}
