android - Gradle Dependency using Make -

i decided give gradle shot in latest project featuring graphics create using gimp.

i use git project , refuse commit exportet .png-graphics in repository. instead want save gimps .xcf files in order able edit graphics later on.

however android application need them .png files , there whole lot of them , trying automate build-process want gradle build .png-graphics .xcf files when executing gradle build.

there plugin featuring imagemagick gradle not work produces images transparency-issues. example:

this image created gradle:

and how should (exportet gimp):

there no hidden layers , not have opacity.

build.gradle:

buildscript {   repositories {     mavencentral()   }    dependencies {     classpath 'com.eowise:gradle-imagemagick:0.4.0'   } }  task build(type: com.eowise.imagemagick.tasks.magick) {     convert 'xcf/', { include '*.xcf' }     'png/'     actions {     -alpha('on')     -background('none')     inputfile()     -flatten()         outputfile { filename, extension -> "${filename}.png" }     } }  task clean() {     filetree tree = filetree (dir: "xcf/");     tree.each { file file ->         file pngfile = new file("png/" + file.name.replacefirst(~/\.[^\.]+$/, '') + ".png")         pngfile.delete()     } } 

the problems seem related imagemagick (source: google), having issues .xcf-files. (i run command on commandline , produces images same issues.)

xcftools

there toolbox called xcftools can export images correctly.

however provided git repository hosted on github , built using gnu build system. (./configure && make).

as assume no 1 building project has xcftools installed , not available distributions.

which why love have dependency leads me question:

how add git-repositories gradle dependency (or repository)?

how make gradle build compile time , use it?
