How to include all src/test/resources/** AND src/main/java/**/*.html in the test sourceset in gradle?

Question

I have the following and thought it was 'adding' to my sourceSet but actually just modified it..

sourceSets {
    test {
        resources {
            srcDirs = ["src/main/java"]
            includes = ["**/*.html"]
        }
    }
}

What I really want is both src/test/resources/** and the above as well. I don't want to exclude any files from src/test/resources though and the above is only including html from any directories I put there.

thanks, Dean

Answer 1

The following will illustrate the technique using main (so it can be verified):

apply plugin: 'java'

sourceSets {
    myExtra {
        resources {
            srcDirs "src/main/java"
            includes = ["**/*.html"]
        }
    }
    main {
        resources {
            source myExtra.resources
        }
    }
}

Proof of concept via the command-line:

bash$ ls src/main/java
abc.html
xyz.txt

bash$ ls src/main/resources/
def.html
ijk.txt

bash$ gradle clean jar
bash$ jar tf build/libs/myexample.jar
META-INF/
META-INF/MANIFEST.MF
abc.html
def.html
ijk.txt

In your case, change main to test. This answer was discovered via the Gradle doc for SourceDirectorySet. Interestingly, for 3.0, it contains a TODO:

TODO - configure includes/excludes for individual source dirs

which implies that this work-around (via this method) is probably necessary.

Answer 2

I got your point. I tried this and it worked . Please take a look into it:

sourceSets {
    test {
        resources {
            srcDirs = ["src/main/java"]
            includes = ["**/*.html"]
        }
    }
}

sourceSets.test.resources.srcDir 'src/test/resources'

Add these in build.gradle.

Answer 3

I was thinking whether or not to post this answer. So that if you are not satisfied with the previous answer, try the following hacky way (probably it will work with eclipse command):

apply plugin: 'java'

ConfigurableFileTree.metaClass.getAsSource = {
  def fileTrees = delegate.asFileTrees
  fileTrees.metaClass.getSrcDirTrees = {
    return delegate as Set
  }
  fileTrees as SourceDirectorySet
}

sourceSets {
  main {
    resources {
      srcDirs = []  // cleanup first
      source fileTree('src/main/java').include('**/*.html').asSource
      source fileTree('src/main/resources').asSource
    }
  }
}
